Jam Code 13-01 is a Tray 3 paper feed misfeed on Konica Minolta bizhub machines equipped with an optional third paper tray. It fires when the machine commands Tray 3 to feed a sheet, but the Tray 3 detection sensor does not confirm the arrival of the paper leading edge within the allowed time window after the feed cycle begins.
Tray 3 is always an optional paper cabinet (PC-110, PC-116, PC-210, PC-216, PC-410, PC-416, PC-113, PC-213, or equivalent depending on the model family). Because it sits below Tray 2, the paper it feeds must travel the longest internal path of any standard tray — through its own feed assembly, up a dedicated vertical transport section inside the paper cabinet, across a bridge section, through the Tray 2 vertical transport zone, and finally into the main machine body for registration. This extended, multi-stage path introduces more potential failure points than Tray 1 or Tray 2, and the diagnosis follows that path from the bottom up: identify where the paper stopped first, then work upward through the feed clutch, vertical transport motor, transport sensor, and inter-cabinet harness connections before considering any board replacement.
| Field | Details |
|---|---|
| Jam Code | 13-01 |
| Description | Misfeed at Tray 3 paper feed section — the Tray 3 detection sensor (feed sensor or vertical transport sensor) is not activated within the allowed time after Tray 3 begins feeding paper |
| Jam Location | Tray 3 paper feed section — from the Tray 3 pickup roller through the feed/separation roller pair, up the Tray 3 vertical transport section to the first detection sensor inside the paper cabinet |
| Detection Logic — MFPB / PFTDB models (758/808/958/C759/C759 etc.): | The leading edge of the paper does not turn ON (block) the Tray 3 paper feed sensor (PS21) even after the lapse of a given period of time after Tray 3 starts to feed paper |
| Detection Logic — BASEB / i-series models (C250i/C300i/C360i/250i/300i/360i with PC-116/PC-216): | After Tray 3 starts to feed paper, the Tray 3 vertical transport sensor (PS113) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the Tray 3 paper feed sensor (PS112) |
| Detection Logic — C4050i with PF-P20/PF-P21: | The leading edge of the paper does not turn ON (unblock) the Tray 3 transport sensor (PS6/3) even after the lapse of a given period of time after Tray 3 starts to feed paper |
| Tray 3 Source | Optional paper cabinet — always an add-on unit. Machine must have a compatible paper cabinet installed for Jam Code 13-01 to be possible |

All Affected Models, Optional Cabinets, and Exact Component References
Because Tray 3 is always an optional paper cabinet, the component references for 13-01 depend on both the base machine model and the specific cabinet model installed. The architecture, motor designations, sensor names, clutch references, connector paths, and control boards are completely different between the two major platform families. Identify your base machine and the installed paper cabinet before running any service mode checks.
Platform Group A: MFPB / PFTDB Machines with CL5 / M25 Architecture
These are typically the high-volume or older A3 bizhub models where Tray 3 is the LCC (Large Capacity Cabinet) fed by a single dedicated paper feed clutch (CL5) and an LCC transport motor (M25). The Tray 3 feed sensor is PS21 and the entire Tray 3 path is monitored by this single sensor. All connector paths run through the Paper Feed/Transport Drive Board (PFTDB).

Platform Group B: PRCB / MFPB Machines with PC-110 / PC-210 / PC-410 Architecture
These are the mid-range A3 bizhub models (C224e, C284e, C364e, C224, C284, C364, C258, C308, C368, C458, C558, C658, 368e, 308e, 458e, 558e, 658e, 227, 287, 367). Tray 3 is always a separately installed paper cabinet (PC-110 for 500-sheet, PC-210 for 1000-sheet, PC-410 for 2500-sheet LCC). The cabinet has its own PC control board (PCCB) and, depending on the cabinet type, either a dedicated paper feed motor (M111 / M131) and vertical transport motor (M112 / M132), or a feed clutch arrangement. Both sensors — the Tray 3 feed sensor (PS112) and the Tray 3 vertical transport sensor (PS113) — are inside the paper cabinet.

Platform Group C: BASEB Machines with PC-116 / PC-216 / PC-416 Architecture
These are the latest-generation i-series and compact i-series bizhub models (C250i, C300i, C360i, 250i, 300i, 360i). They use the same paper cabinets as Group B but route sensor and motor signals differently — through the PCCB and then to the BASEB. For 13-01, two sensors are checked: the Tray 3 feed sensor (PS112) inside the cabinet and the Tray 3 vertical transport sensor (PS113), also inside the cabinet. The Tray 3 vertical transport motor (M112 or M132) is the dedicated drive for the transport section in the cabinet.

Platform Group D: BASEB + PCCB/3 Machines (C4050i with PF-P20 / PF-P21)
On the bizhub C4050i, Tray 3 is available only when the PF-P20 or PF-P21 paper feed unit is installed. Each tray in this architecture has its own drive motor (M1/3), feed clutch (CL1/3), and transport clutch (CL2/3), and its own PC control board (PCCB/3). The transport sensor is PS6/3.

ℹ️ Critical first step before any service mode work: Identify your base machine model AND the paper cabinet model installed (check the nameplate on the side of the cabinet), then locate the correct platform group above. The motor designations (M111 vs M131 vs M25), sensor references (PS112 vs PS21 vs PS6/3), and board paths (PCCB → MFPB vs PCCB → BASEB vs PFTDB → MFPB) are completely different across platform groups. Checking the wrong connector pins or running the wrong motor check code produces misleading results.
What Does Jam Code 13-01 Mean?
Tray 3 sits at the bottom of the paper feed stack in the optional paper cabinet positioned below the base machine. Because it is the lowest standard paper source, the sheet it feeds must travel the longest internal path before it reaches the registration roller and imaging section. On most bizhub configurations, this path involves:
- The Tray 3 lift mechanism raising the paper stack to contact the Tray 3 pickup roller
- The Tray 3 paper feed motor (M111 / M131) or feed clutch (CL5) engaging to drive the pickup and feed rollers inside the Tray 3 paper feed unit
- The Tray 3 feed roller driving the sheet forward while the Tray 3 separation roller prevents double-feeding
- The paper leading edge triggering the Tray 3 paper feed sensor (PS112 / PS21) — confirming the sheet has left the feed nip point
- The Tray 3 vertical transport motor (M112 / M132 / M25) driving the sheet upward through the cabinet’s internal vertical transport section
- The paper leading edge triggering the Tray 3 vertical transport sensor (PS113 / PS133) — confirming the sheet has cleared the cabinet’s vertical section
- The sheet then continues upward through the Tray 2 vertical transport section (controlled by CL2 in the base machine) and into the main paper path
- Jam Code 13-01 fires if the detection sensor does not activate within the allowed time at the appropriate point in this sequence
There are five primary failure scenarios for 13-01, each with a distinct diagnostic signature:
- Scenario A — Tray 3 roller wear or one-way clutch slipping: The Tray 3 pickup roller, feed roller, or separation roller is glazed, worn, or the one-way clutch bearing that transfers drive from the shaft to the roller has slipped on a polished shaft. Paper does not leave the Tray 3 feed assembly, or barely moves before stalling. This is the most common cause on machines with high Tray 3 usage
- Scenario B — Tray 3 paper feed motor (M111 / M131) or feed clutch (CL5) failure: The motor that drives the Tray 3 feed rollers (in platform groups B and C) or the feed clutch CL5 (in platform group A) is not engaging. With no drive reaching the feed assembly, no paper movement occurs from the moment the feed cycle is commanded
- Scenario C — Tray 3 vertical transport motor (M112 / M132 / M25) failure: The feed rollers pick up and move the paper, but the motor that drives the vertical transport section inside the cabinet is not turning. Paper exits the feed nip but stalls in the cabinet’s vertical transport zone before triggering the feed sensor or vertical transport sensor
- Scenario D — Cabinet inter-unit harness or PCCB communication fault: The paper cabinet has its own PC control board (PCCB) that communicates with the base machine’s main board (MFPB / BASEB) through a harness that runs between the cabinet and the machine. A loose, damaged, or disconnected inter-unit harness produces a total loss of Tray 3 function — no drive is sent, no sensor data is received, and 13-01 fires on every print from Tray 3. This is particularly common after the machine has been moved, after a PM visit where the cabinet was opened, or if the machine has experienced a collision or rough handling
- Scenario E — Tray 3 detection sensor failure or obstructed actuator: Paper is feeding and transporting correctly but the Tray 3 feed sensor (PS112 / PS21) or vertical transport sensor (PS113 / PS133) has failed, its connector is loose, or the sensor actuator flag is bent, broken, or obstructed. The machine never receives confirmation of paper arrival and fires 13-01 on a timeout
Step 1 — Clear the Paper and Identify the Stopped Position
Because the Tray 3 path is long and multi-stage, identifying exactly where the paper stopped is even more important for 13-01 than for 11-01 or 12-01. Each stopping location maps to a specific failure component.
- Open the paper cabinet right-side door or access cover as directed by the panel to expose the Tray 3 paper path. Also open the base machine right-side cover — paper from Tray 3 that passed through the cabinet may have stalled in the base machine’s vertical transport zone
- Remove any jammed paper carefully — always pull in the direction of paper travel. In the vertical transport section, paper should be pulled upward, not downward
- Pull out Tray 3 and check inside the tray cavity and behind the feed assembly for paper fragments
- Note exactly where the paper stopped:
- Paper did not move from Tray 3 at all: Scenario B (Tray 3 feed motor M111/M131 or clutch CL5 not engaging) or Scenario A (one-way clutch slipping with no paper movement generated). Proceed to Step 5
- Paper moved slightly but stopped within the Tray 3 feed assembly area: Scenario A (one-way clutch slipping on feed roller shaft) or Scenario B (partial motor engagement). Proceed to Step 3 for roller and clutch inspection
- Paper exited the feed nip but stopped in the cabinet’s vertical transport section (between the feed rollers and the cabinet top): Scenario C (Tray 3 vertical transport motor M112/M132/M25 not running) or the vertical transport roller inside the cabinet is glazed. Proceed to Step 6
- Paper exited the cabinet but stopped in the base machine’s Tray 2 vertical transport zone: The Tray 3 feed and transport motors worked correctly, but the Tray 2 vertical transport clutch (CL2) in the base machine did not engage to carry the paper further. This is a 20-21 companion fault, not a pure 13-01 cause — proceed to Step 7 to check CL2
- No paper found anywhere in the path, but 13-01 fired: Scenario D (PCCB communication fault or inter-unit harness disconnected — no drive commands reached the cabinet at all) or Scenario E (sensor fault). Proceed to Step 4 to check the inter-unit harness first
- Inspect the stopped paper for damage patterns:
- Leading edge crumpled in cabinet feed area: Pickup roller pushed paper, feed roller did not turn — one-way clutch on feed roller shaft slipping
- Paper stopped cleanly in vertical transport with no crumpling: Feed rollers worked, vertical transport motor M112/M132/M25 not running or transport roller glazed
- Multiple sheets feeding simultaneously from Tray 3: Separation roller torque limiter failed — retard function lost
Step 2 — Check Paper Loading and Tray 3 Condition
Paper condition issues in the paper cabinet are common in office environments and are the fastest non-technical fix when they are the root cause.
- Pull Tray 3 completely out of the paper cabinet
- Remove all paper and fan the stack thoroughly. Paper that has been sitting in a low-use cabinet for extended periods can absorb moisture and cause sheets to stick together. This is particularly common in Tray 3, which is often used as overflow capacity and sees less daily cycling than Trays 1 and 2
- Confirm the paper is within specification: correct weight (typically 60–90 g/m² for standard operation), correct size for the tray size guides, and not exceeding the maximum fill line marked in the cabinet
- Check that the side guides and end guide are correctly adjusted — lightly contacting the paper stack edges without squeezing. Over-tight guides resist feeding; loose guides cause skewing and dog-ear misfeeds
- Confirm Tray 3 is fully and correctly inserted into the cabinet — push firmly until it clicks into the fully seated position. A tray that appears closed but is not fully engaged may prevent the Tray 3 lift mechanism from raising the stack to the correct pickup height
- Reload fresh paper from a sealed ream and attempt a 10-page test print from Tray 3. If 13-01 does not recur, the cause was paper condition or loading
Step 3 — Inspect the Tray 3 Pickup, Feed, and Separation Rollers
Tray 3 roller wear is a common cause of 13-01 on machines where Tray 3 handles significant volume. Inspection takes only a few minutes with the cabinet access door open.
- Pull Tray 3 out of the cabinet and look up into the tray cavity to inspect the pickup roller — it should have a textured rubber surface. A shiny, flat, or cracked surface indicates a roller that needs replacement
- Access the Tray 3 paper feed unit (the slide-out or hinged unit inside the cabinet containing the feed and separation rollers). The exact access procedure varies by cabinet model — refer to the specific paper cabinet service manual section for the model installed
- Inspect:
- Feed roller: Same surface inspection as the pickup roller — should be textured, not glazed
- Separation roller: Check for glazing, cracking, or wear. Manually rotate the separation roller: it should turn in the feed direction with light resistance and resist turning against it. A separation roller that spins freely in both directions means the torque limiter has failed — replace the separation roller assembly
- Pickup roller bracket spring: Check that the spring applying downward pressure to the pickup roller bracket is intact and in position. A missing or broken spring reduces pickup pressure and causes intermittent no-feed
- Clean all roller surfaces with a damp lint-free cloth — never use IPA or chemical solvents on rubber feed rollers
- If any roller is glazed, cracked, or flat-spotted, replace the complete Tray 3 roller set as a unit
⚠️ Critical — Replace Tray 3 one-way clutch bearings with every roller PM: The one-way clutch bearings on the Tray 3 pickup and feed roller shafts wear at the same rate as the rollers and are not included in most standard roller PM kits. Installing new rollers on worn one-way clutches that are slipping on a polished shaft reproduces 13-01 within days of the PM. This is the single most common cause of Tray 3 callback calls following roller replacement. Always order and replace the one-way clutches as part of any Tray 3 roller service.
Step 4 — Inspect and Reseat the Inter-Unit Harness Between the Paper Cabinet and the Base Machine
This step is unique to Tray 3 (and lower trays) and has no equivalent in Tray 1 or Tray 2 troubleshooting. The paper cabinet communicates with the base machine through a multi-pin harness connector that bridges the two units. This harness carries the drive signals to the cabinet motors and clutches, and the sensor feedback signals back to the main control board. A loose, partially disconnected, or damaged inter-unit harness produces a total or intermittent loss of Tray 3 function and is one of the most common causes of 13-01 after a machine has been moved or serviced.
- Power OFF and unplug the machine
- Locate the inter-unit harness connector between the paper cabinet and the base machine body — on most bizhub models with PC-110/PC-210/PC-116/PC-216/PC-410/PC-416, this is a multi-pin connector at the rear of the cabinet-to-machine junction, typically accessible after removing the rear cover of the base machine or the rear cover of the cabinet. On LCC-equipped models (758/808/958/C759), the cabinet harness connects through a similar rear connection point
- Disconnect the inter-unit harness connector from both ends and inspect the pins closely:
- Bent or pushed-back pins are a common damage pattern when the cabinet has been removed and reinstalled without fully aligning the connector
- Corrosion or toner contamination on the connector pins disrupts signal continuity intermittently
- A connector housing that appears seated but has not fully latched — check that the latch clip is fully engaged on both ends
- Also check the PCCB (PC control board inside the paper cabinet) connector. On PC-110/PC-210/PC-116/PC-216 cabinets, the PCCB is mounted on the rear wall of the cabinet. Reseat all connectors on the PCCB — these can work loose from vibration over time
- Reconnect everything firmly, power on, and attempt a 10-page test print from Tray 3. If 13-01 clears, the harness connection was the cause. Monitor for recurrence — if the error returns within a few cycles, the connector housing or pin contact is degraded and should be replaced
ℹ️ Field tip — 13-01 appearing suddenly after a PM or machine move: When 13-01 appears for the first time immediately after a PM visit, machine relocation, or any service that involved separating or opening the paper cabinet, the inter-unit harness connector is the first thing to check — before entering service mode. A connector that was not fully reseated after the cabinet was opened or moved reproduces 13-01 on every print from Tray 3 and clears immediately when the connector is properly seated. This is a zero-cost fix that takes two minutes.
Step 5 — Check the Tray 3 Paper Feed Motor (M111 / M131) or Feed Clutch (CL5) in Service Mode
If rollers and one-way clutches are confirmed good, the inter-unit harness is firmly connected, but 13-01 persists with no observable paper movement from Tray 3, check whether drive is reaching the Tray 3 feed assembly.
For Platform Group A (PFTDB models — 758/808/958/C759/C659 with CL5 / M25):
- Enter Service Mode
- Navigate to the load / clutch operation check section
- Command CL5 (Tray 3 paper feed clutch) to engage: Signal: PFTDB CN16-5 (REM), Check code: 20, Multi code: 3, Location: 5-X
- Listen for CL5 clicking and engaging. With Tray 3 removed, manually rotate the pickup roller shaft — it should lock when CL5 is energized and spin freely when de-energized
- If CL5 does not engage, check the connector and test coil continuity. Open circuit confirms a failed CL5 coil — replace CL5
- Then check the PFTDB board fuses (F12 or F15) for continuity — a blown fuse removes power from the CL5 drive circuit. If the fuse has blown, confirm CL5 is not seized before fitting a replacement fuse or board
For Platform Groups B and C (PCCB models — PC-110/PC-116/PC-210/PC-216 with M111 / M112):
- Enter Service Mode
- Navigate to the motor load check section
- Command M111 (Tray 3 paper feed motor) to run: Signal: PCCB CN5-5 (CW/CCW), Location: PC-110/PC-210 4-C (or PC-116/PC-216 equivalent)
- Listen for M111 running and observe whether the Tray 3 feed rollers turn when the motor runs. If M111 runs but rollers do not turn, the drive coupling between M111 and the feed roller shaft has failed — inspect the gear train inside the cabinet
- If M111 does not run:
- Check the connector between M111 and PCCB CN5 for proper seating
- Check the PCCB connector to the base machine MFPB/BASEB harness — if PCCB is not receiving power or communication signals from the base machine, no motor commands are executed
- Test M111 coil resistance with a multimeter: confirm the motor windings are intact before concluding a board fault
- Replace M111 if the coil is open-circuit or the motor turns with abnormal resistance
For Platform Group D (C4050i with PF-P20/PF-P21 — CL1/3 and M1/3):
- Enter Service Mode
- Command CL1/3 (Tray 3 feed clutch) to engage: Check code: 20, Multi code: 3, Signal: PCCB/3 CN5-3 (ON), Location: 16-P
- If CL1/3 engages correctly, command M1/3 (Tray 3 drive motor) to run: Check code: 28, Multi code: 3 or 4, Signal: PCCB/3 CN4-1 to 7, Location: 18-P
- Check the PCCB/3 connector to BASEB for proper seating if either the clutch or motor fails to respond
Step 6 — Check the Tray 3 Vertical Transport Motor in Service Mode
If the feed motor (M111/M131) or clutch (CL5) is confirmed working and paper exits the Tray 3 feed rollers but stops in the cabinet’s vertical transport section, the Tray 3 vertical transport motor (M112 / M132 / M25) is the next component to check. This is the motor that carries the sheet upward through the cabinet once it leaves the feed rollers — without it running, paper always stops in the cabinet’s vertical transport zone.
For Platform Group A (M25 — LCC transport motor on 758/808/958/C759/C659):
- In Service Mode, navigate to the motor load check section
- Command M25 (LCC transport motor) to run: Signal: PFTDB CN13-1 to 7, Location: 11-X
- Listen for M25 running. If M25 does not run, check the connector between M25 and PFTDB CN13. Test M25 winding continuity. Check PFTDB F12 or F15 fuse continuity before replacing the motor or board
For Platform Groups B and C (M112 / M132 — Tray 3 vertical transport motor on PC-110/PC-116/PC-210/PC-216/PC-410/PC-416):
- In Service Mode, navigate to the motor load check section
- For PC-110 / PC-116 / PC-210 / PC-216: Command M112 to run: Check code: 28, Multi code: 21, 24, 25, Signal: PCCB CN5-9 to 16, Location: PC-116/PC-216 3 to 4-C (or PC-110/PC-210 equivalent)
- For PC-410 / PC-415 / PC-416: Command M132 to run: Check code: 28, Multi code: 6, 9, 10, Signal: PCCB CN5-9 to 16, Location: PC-416 4-J (or PC-410/PC-415 equivalent)
- Confirm the vertical transport roller inside the cabinet turns when the motor runs — with the cabinet access door open, visually observe the transport roller for rotation
- If M112 / M132 runs but the transport roller does not turn, inspect the drive coupling between the motor and the roller shaft — a stripped gear tooth or failed coupling is the cause
- If M112 / M132 does not run, check:
- The connector between M112/M132 and PCCB CN5
- The inter-unit harness between PCCB and the base machine board (MFPB / BASEB) — an open circuit in the harness prevents check code commands from reaching the PCCB
- PCCB power supply — if the PCCB is not receiving the 24V drive voltage from the base machine, no motor will run regardless of the service mode command
For Platform Group D (C4050i — CL2/3 transport clutch and M1/3 drive motor):
- Command CL2/3 (Tray 3 transport clutch) to engage: Check code: 21, Signal: PCCB/3 CN5-1 (ON), Location: 15-P
- Confirm the transport roller receives drive when CL2/3 is engaged during an M1/3 motor run check
Step 7 — Check the Tray 2 Vertical Transport Clutch (CL2) in Service Mode
After paper exits the Tray 3 cabinet successfully, it must pass through the Tray 2 vertical transport section inside the base machine before reaching the registration area. The Tray 2 vertical transport clutch (CL2) in the base machine controls this section. A failure of CL2 causes Tray 3 paper to stall above the cabinet but below the base machine registration area — this is the 20-21 companion failure to 13-01 and is often misdiagnosed as a Tray 3 cabinet fault when the actual problem is in the base machine.
- In Service Mode, navigate to the load / clutch check section
- Command CL2 (Tray 2 vertical transport clutch in the base machine) to engage using the model-specific check signal:
- C250i / C300i / C360i / 250i / 300i / 360i: Check code: 21, Multi code: 1, Signal: BASEB CN23E-19 (ON), Location: 17-K
- C224e / C284e / C364e / C258 / C308 / C368 / C458 / C558 / C658 and related: Refer to model-specific service manual for CL2 check signal on MFPB or PRCB
- If CL2 does not engage, the fault is in the base machine — the Tray 3 cabinet is functioning correctly but the base machine is not collecting the paper from the top of the cabinet. Check CL2 connector seating, test CL2 coil continuity, and replace CL2 if the coil is open-circuit
- If CL2 engages correctly, the fault is upstream — inside the paper cabinet. Continue with Steps 5 and 6
Step 8 — Check the Tray 3 Detection Sensors in Service Mode
If the feed motor, vertical transport motor, and CL2 are all confirmed working, but 13-01 still fires, the Tray 3 feed sensor (PS112 / PS21) or vertical transport sensor (PS113 / PS133) may have failed or its actuator flag may be obstructed.
- Enter Service Mode and navigate to the sensor I/O check section
- Monitor the Tray 3 feed sensor at the connector pin shown in the model reference table above (e.g., PCCB CN4-14 for PC-116/PC-216 on C250i/C360i, or PFTDB CN17-9 for PS21 on 758/808/958)
- With no paper in the Tray 3 path: the sensor should read OFF (unblocked)
- Manually slide a sheet of paper into the Tray 3 feed section so the leading edge passes the sensor position — the sensor should switch to ON (blocked) as the paper crosses the beam, and return to OFF when the paper is removed
- Also check the Tray 3 vertical transport sensor (PS113 / PS133) using the same procedure — manually feed paper upward through the cabinet until it crosses the vertical transport sensor position
- Interpret:
- Both sensors switch correctly during manual paper positioning: Sensors are functional. The fault is in the powered drive path — motors, clutches, or one-way clutches are not delivering paper to the sensor positions during a print cycle
- A sensor reads ON permanently with no paper present: Sensor failed in the blocked state, or a paper fragment is lodged in the sensor beam slot. Open the cabinet access door and inspect the sensor slot for debris — a torn paper fragment is a very common cause of a falsely triggered sensor in the cabinet’s vertical section. If the slot is clear, replace the sensor
- A sensor does not switch ON when paper is manually positioned across the beam: Inspect the sensor actuator flag — the small plastic tab that enters the sensor beam. If the flag is bent, broken, or missing, replace it before replacing the sensor. If the flag is intact and the sensor still does not respond, the sensor has failed — replace it
Step 9 — Inspect the Tray 3 Vertical Transport Roller Inside the Cabinet
On machines where the vertical transport motor (M112 / M132 / M25) runs correctly but paper still stalls in the cabinet’s vertical transport section, the vertical transport drive roller inside the cabinet may be glazed or contaminated — exactly the same failure mode as in the base machine’s Tray 2 vertical transport section.
- Open the paper cabinet access door or right-side door to expose the vertical transport roller inside the cabinet
- Locate the vertical transport drive roller — on most paper cabinets this is a rubber-covered roller mounted in the upper section of the cabinet body, forming a nip with a spring-loaded idle roller. It carries paper from the feed assembly level upward to the cabinet exit point
- Inspect the drive roller surface — it should be textured rubber. A glazed or contaminated surface provides insufficient grip to carry paper upward against gravity, particularly on heavier stock weights
- Clean the roller surface with a damp lint-free cloth. Also clean the idle rollers that press against it
- Check the spring tension behind the idle rollers — weakened springs reduce nip pressure on the paper, allowing it to slip through the transport zone without being reliably driven upward. This is the same spring fatigue mechanism documented on the bizhub 4-series base machine vertical transport, and can occur in the paper cabinets of those models as well
- If the drive roller is glazed beyond what cleaning can restore, replace it with the correct roller for the installed cabinet model
Step 10 — Check the One-Way Clutch Bearings on the Tray 3 Feed Assembly
When roller inspection confirms the rubber surfaces appear adequate but 13-01 continues intermittently — particularly on machines with high Tray 3 usage — the one-way clutch bearings on the pickup roller and feed roller shafts are the likely cause. The failure mechanism is identical to Trays 1 and 2: the shaft surface becomes mirror-polished from wear, and the one-way clutch bearing can no longer grip the shaft in the drive direction.
- Remove the Tray 3 paper feed assembly from the cabinet per the cabinet-specific service manual procedure
- Remove the pickup roller and feed roller from their shafts by releasing the C-clips or E-rings
- Remove the one-way clutch bearings from the shafts and inspect the shaft surface:
- If mirror-polished or showing circular wear grooves felt with a fingernail, replace the shaft along with the bearing
- If smooth but not grooved, lightly texture the shaft with a fine Scotch-Brite pad moving along (not around) the shaft axis, then wipe clean
- Install new one-way clutch bearings — confirm the orientation before pressing them on. The roller should lock when turned in the feed direction and spin freely when turned against it
- Reinstall the assembly, insert Tray 3, and run a 20-page test print from Tray 3 to confirm stable operation
Step 11 — Replace the PCCB (Paper Cabinet PC Control Board)
If all motors and clutches operate correctly when commanded in service mode, sensors switch reliably, the inter-unit harness is confirmed good, rollers and one-way clutches are new, and 13-01 still fires consistently from Tray 3, the PCCB inside the paper cabinet is the most likely remaining fault — particularly if the fault appeared suddenly without any mechanical change.
- Power OFF and unplug the machine and the paper cabinet
- Access the PCCB inside the paper cabinet — on most bizhub cabinets the PCCB is mounted on the rear wall of the cabinet, accessible after removing the rear cover
- Before removing the PCCB, note or photograph all connector positions — some models have multiple similar-looking connectors that are easy to swap accidentally during reassembly
- Reseat all connectors on the current PCCB and power on to rule out a loose board connector before committing to board replacement
- If reseating does not resolve the issue, replace the PCCB with the correct part number for the specific cabinet model (PC-110, PC-116, PC-210, PC-216, PC-410, PC-416, or equivalent)
- After fitting the replacement PCCB, reconnect all harnesses carefully, power on, and run a 20-page Tray 3 print test before fully reassembling the cabinet
ℹ️ Field tip — Multiple feeds with 13-01 on 654e / 754e / C754e with LCC (Tray 3): A documented and difficult-to-diagnose 13-01 variant on the bizhub 654e, 754e, and C754e involves multiple sheets being fed simultaneously from the LCC tray (Tray 3) — three sheets appear in different sections of the paper path simultaneously on a single-page job. This is caused by a clutch in the Tray 1 or Tray 2 feed section firing at the wrong time (a ghost energization), which pulls paper from Tray 3 prematurely and produces a multi-sheet path blockage that reads as 13-01. The diagnostic technique for this is to pull all trays out of the machine and push them in one at a time, using differently colored paper in each tray to track which tray’s paper appears where. Replacing the suspect clutch (often CL1 or CL2 in the adjacent feed section) resolves this variant — not replacing the Tray 3 feed assembly or PCCB.
Step 12 — Replace the Base Machine Control Board (Last Resort)
If the PCCB has been replaced, all Tray 3 motors and clutches are confirmed good, sensors are confirmed switching, the inter-unit harness is verified intact, and 13-01 persists, the fault is in the base machine control board’s ability to communicate with or power the paper cabinet PCCB.
- Replace MFPB — bizhub C258/C308/C368, C224e/C284e/C364e, C458/C558/C658, 458e/558e/658e, 368e/308e, 227/287/367
- Replace BASEB — bizhub C250i/C300i/C360i, 250i/300i/360i
- Replace PCCB/3, then BASEB — bizhub C4050i (try PCCB/3 before BASEB for isolated Tray 3 codes)
- Replace PFTDB, then MFPB — bizhub 758/808/958/654e/754e/C759/C659 (try PFTDB before MFPB for isolated Tray 3 codes)
- Replace PRCB or MFPB — bizhub C224/C284/C364, 223/283/363/423 (refer to SM for specific board order)
Quick Reference — Troubleshooting by Symptom
| Symptom | Most Likely Cause | First Action |
|---|---|---|
| 13-01 appears suddenly after a PM visit, machine move, or paper cabinet removal/reinstall | Inter-unit harness between paper cabinet and base machine not fully reconnected | Power OFF; locate and reseat the inter-unit harness connector at both ends; check PCCB connectors inside cabinet |
| 13-01 on every print from Tray 3 — paper does not move at all | Tray 3 feed motor (M111/M131) not running, or feed clutch (CL5) not engaging, or inter-unit harness disconnected | Reseat inter-unit harness first; then command M111/M131 or CL5 in service mode; if no response, check PCCB power and harness continuity |
| 13-01 intermittently — Tray 3 works most of the time but misfeeds 1 in every 20–50 pages | One-way clutch bearing slipping on polished feed roller shaft | Remove Tray 3 feed assembly, inspect shaft surface under one-way clutch, replace one-way clutches and lightly texture shaft |
| Paper exits Tray 3 feed rollers and stops in the cabinet’s vertical transport section | Tray 3 vertical transport motor (M112/M132/M25) not running, or vertical transport drive roller glazed | Command M112/M132/M25 in service mode; if motor runs, inspect cabinet vertical transport roller surface and idle roller spring pressure |
| Paper exits the cabinet completely but stops in the base machine vertical transport zone | Tray 2 vertical transport clutch (CL2) in the base machine not engaging — Tray 3 cabinet is working correctly | Command CL2 in service mode on the base machine; if CL2 does not engage, check connector and coil continuity; replace CL2 |
| 13-01 from Tray 3 only — Trays 1 and 2 feed perfectly | Tray 3 feed motor (M111/M131/CL5), one-way clutch, roller wear, or PCCB cabinet board fault | Work through Steps 3–6 in order; check M111/M131 or CL5 in service mode |

Understanding the 13-xx Tray 3 Jam Code Family
Jam Code 13-01 belongs to a sub-family of Tray 3 feed section codes. Understanding the complete family allows correct interpretation when multiple codes appear together or when a sub-code other than 13-01 is displayed:
- 13-01 — Tray 3 misfeed — paper leading edge did not trigger the Tray 3 detection sensor within the allowed time. Primary Tray 3 no-feed code. This article
- 13-05 — On models with two Tray 3 sensors (PS112 and PS113): the Tray 3 feed sensor (PS112) was never activated — paper did not even leave the feed nip point. This is earlier in the path than 13-01. If 13-05 fires, the fault is definitively in the Tray 3 feed assembly or M111/M131 motor — the paper never moved at all. 13-01 may also fire alongside 13-05 when the primary sensor was not triggered
- 13-40 — Tray 3 image write signal timeout — the image write start signal permit remained disabled for longer than allowed after the expected output timing. More often board-timing-related than mechanically caused, and less common than 13-01 in the field
- 20-21 — Paper from Tray 3 successfully activated the Tray 3 vertical transport sensor (PS113) but then did not reach the Tray 2 vertical transport sensor (PS19) in the base machine within the allowed time. This is a cross-boundary jam — the cabinet did its job, but the base machine’s CL2 clutch did not collect the paper at the top of the cabinet. When 13-01 and 20-21 appear together, the Tray 3 cabinet feed path is confirmed good and CL2 in the base machine is the fault
- 20-22 — Paper from Tray 4 successfully activated the Tray 4 vertical transport sensor but did not reach the Tray 3 vertical transport sensor (PS113) within the allowed time. This is a Tray 4 → Tray 3 inter-cabinet transport failure that appears alongside 14-01
- C0106 — Tray 3 / LCT paper feed motor (M111 / M131) turning at abnormal timing — the motor lock signal behaves unexpectedly while the motor is commanded to run. This is an error code (not a jam code) that fires when M111 / M131 runs but at the wrong speed or stalls. When C0106 accompanies 13-01, the motor is present but mechanically overloaded or has a failing winding
- C0107 — Tray 3 / LCT vertical transport motor (M112 / M132) turning at abnormal timing — same detection logic as C0106 but for the vertical transport motor. When C0107 accompanies 13-01, M112 / M132 is present but running abnormally — inspect the motor, its connector, and the PCCB
Preventing Jam Code 13-01 From Recurring
- Always replace Tray 3 one-way clutch bearings with every roller PM — exactly as for Tray 1 and Tray 2. One-way clutches are the dominant Tray 3 roller callback cause and are not included in most PM kits. Order them separately and treat them as a mandatory PM item on every Tray 3 roller service
- Lightly texture Tray 3 roller shafts at every roller PM — use a fine Scotch-Brite pad along (not around) the shaft to restore grip texture where the one-way clutch rides. Wipe clean before fitting the new bearing. Never use coarse abrasive or create circular grooves
- Inspect and firmly reseat the inter-unit harness at every PM that involves the paper cabinet — any time the paper cabinet is opened, detached, or repositioned, the inter-unit harness connector should be inspected for bent pins and reseated as a standard PM step. This 60-second check prevents the most common cause of post-PM 13-01 callback calls
- Check the PCCB connectors inside the cabinet at every PM — vibration from normal machine operation gradually loosens the PCCB board connectors over time. Reseating them during PM prevents intermittent 13-01 that appears between PM intervals
- Inspect the Tray 3 cabinet vertical transport roller and idle roller spring pressure at every PM — particularly on high-volume Tray 3 installations. A glazed vertical transport roller or weakened idle spring is a predictable wear item that can be caught and corrected during PM before it causes a service call
- Run a 20-page feed test from Tray 3 after every PM — marginal one-way clutch grip that slips on the 12th sheet but not the first three will not be detected by a short functional test. A 20-page run catches borderline issues before the customer notices them. This is especially important for Tray 3 because its lower usage rate means a PM-related issue may not show up for days after the PM visit if only a brief test is run
- Check paper storage condition in the paper cabinet at every PM — Tray 3 is often the lowest-volume tray and paper can remain in it for weeks or months. Damp or compressed paper causes intermittent misfeed that appears mechanical. Advise customers to store paper in a cool, dry location, and check the paper condition in Tray 3 specifically during each PM visit
Professional Technician Summary
Jam Code 13-01 on Konica Minolta bizhub machines is a Tray 3 paper feed misfeed from an optional paper cabinet, and it is the most complex tray misfeed to diagnose because the paper path spans two independent units — the paper cabinet and the base machine — each with its own motors, clutches, sensors, and control board.
The most important first step is to identify the exact paper stopping position before entering service mode. Paper stopped inside the cabinet’s feed zone points to rollers, one-way clutches, or the Tray 3 feed motor (M111/M131/CL5). Paper stopped in the cabinet’s vertical transport zone points to the Tray 3 vertical transport motor (M112/M132/M25). Paper stopped above the cabinet in the base machine zone points to CL2 in the base machine — a 13-01 companion fault that is actually a base machine failure, not a cabinet failure.
The second most important step — often skipped in the field — is to check the inter-unit harness connector between the paper cabinet and the base machine. A connector that was not fully reseated after a PM visit or machine move is the cause of a significant number of 13-01 first-occurrence calls and takes two minutes to inspect and resolve. This check should always precede any service mode work.
When all mechanical, harness, and clutch checks are clean but 13-01 persists, the PCCB inside the paper cabinet is the correct replacement before the base machine control board. The PCCB is the command and feedback hub for all Tray 3 functions and is far more likely to have failed in isolation than the base machine board on a call where all other trays are feeding normally. On PFTDB-equipped models (758/808/958/654e/754e), replace the PFTDB before the MFPB for isolated Tray 3 codes. On i-series machines (C250i/C360i), replace the PCCB cabinet board before the BASEB.
Finally, on the bizhub 654e/754e/C754e, be alert for the documented ghost-clutch multi-sheet 13-01 variant. When three sheets appear simultaneously in different sections of the paper path on a single-page job from Tray 3, the root cause is a clutch in a neighboring tray’s feed section firing at the wrong time — replace the ghost-firing clutch rather than working through the Tray 3 cabinet components.
