Konica Minolta bizhub — Error Code C0206: Tray 3 Lift-Up Failure

Error Code C0206 is a Rank B paper feed fault generated when the bizhub detects that the Tray 3 paper stack has failed to reach the upper feed position within the allowed time after the lift-up operation was initiated. Unlike the motor-timing faults in the C0106–C0109 family, which detect abnormal motor lock signals, C0206 is a position feedback failure — the lift mechanism was commanded to raise the paper stack, but the tray 3 upper limit sensor (PS116) never confirmed that the stack reached the correct height for feeding to begin.

C0206 therefore has a broader root cause profile than a pure motor fault. It can result from anything that prevents PS116 from seeing the tray platform reach its upper limit: a failed lift-up motor, a broken drive coupling, a paper overload in the tray, a jammed lift mechanism, a faulty or misaligned sensor, a broken sensor harness, or a failed PCCB or MFPB that cannot drive the motor or read the sensor correctly. Identifying which of these is responsible requires a structured approach — starting always with the simplest mechanical checks before moving to electrical component replacement.

C0206 applies exclusively to machines fitted with an optional paper feed cabinet that provides Tray 3 lift functionality. It is not generated by a base-configuration machine without such a cabinet installed.

ℹ️ Note: The bizhub C654/C754 platform uses a different paper feed tower architecture with a dedicated PFTDB (Paper Feed Tower Drive Board). On these models, C0206 is described as a Tray 3 feeder up/down abnormality and involves motor M23, the PFTDB connector CN18, and sensor PS22 connected through a multi-relay path to PFTDB CN20. The component designations, connector paths, and board architecture differ significantly from those of the cabinet-based models covered in the main article — refer to the bizhub C654/C754 service manual in full for this platform.

What Does Error Code C0206 Mean?

Every bizhub tray uses a lift-up mechanism to raise the paper stack so that the topmost sheet reaches the pick-up roller height required for reliable paper separation and feeding. For Tray 3 in the paper feed cabinet, this lift is performed by the Tray 3 lift-up motor (M113), which drives a gear train connected to a platform mechanism beneath the paper stack. When the tray is pushed in after paper loading, the PCCB commands M113 to begin raising the platform. Simultaneously, the PCCB begins monitoring the Tray 3 upper limit sensor (PS116) — a photo-interrupter or actuator-based sensor positioned at the height the paper stack must reach for the pick-up roller to engage the top sheet correctly.

If PS116 does not signal that the paper stack has reached the upper position within the machine’s predetermined timeout period after M113 was commanded to run, the PCCB halts the machine and logs C0206. This timeout-based detection means C0206 can be triggered by any failure that prevents the platform from reaching the correct height — whether the motor never ran at all, the motor ran but stalled before reaching height, the platform reached height but PS116 could not report it, or the motor ran and PS116 reported correctly but the signal never reached the PCCB.

This detection logic is fundamentally different from the C0106–C0109 motor lock signal family. Those codes detect instantaneous motor electrical faults. C0206 detects a position outcome failure: the end result — paper stack at correct height — was not achieved within the allowed time, for whatever reason.

ℹ️ Key point: Because C0206 is a position outcome fault rather than an instantaneous motor fault, the list of possible root causes is broader than for C0106–C0109. A mechanical overload, paper jam beneath the platform, overfilled tray, broken lift coupling, faulty sensor, open harness, or failed board can all produce exactly the same C0206 code. Always begin with the simplest and most accessible mechanical checks before proceeding to electrical diagnosis.

How the Tray 3 Lift Mechanism Works

Understanding the physical sequence of the Tray 3 lift cycle helps direct the inspection correctly:

The technician or user loads paper into Tray 3 and pushes the tray fully into the cabinet.
As the tray reaches the fully seated position, the PCCB detects tray insertion and commands M113 to begin running in the lift-up direction.
M113 drives a gear reduction train that rotates a cam or lead-screw mechanism beneath the tray platform, causing the platform and paper stack to rise.
As the platform rises, the top sheet of the paper stack approaches the pick-up roller level. A flag or reflector mounted on the platform, or on the top sheet itself depending on the model, moves into the detection field of PS116.
When PS116 is blocked (actuated) by the rising platform flag, it sends an ON signal to the PCCB via the relay connector CN24 and PCCB CN4 pin 3.
The PCCB reads PS116 ON and stops M113. The tray is now in the ready-to-feed state and the machine proceeds to the print-ready condition.

C0206 fires when step 5 does not complete within the allowed timeout after step 2 began. Any failure anywhere in this sequence — mechanical, electrical, or sensor-related — results in the same code.

Common Causes of C0206

Paper overloaded in Tray 3 beyond the maximum fill line — the most common and most easily overlooked cause. Overfilling increases the weight and friction the lift mechanism must overcome. M113 may stall before the stack reaches PS116, or the lift may reach height but with the paper stack packed so high that PS116 is triggered prematurely then released. Always check the paper fill level first before any electrical diagnosis.
Paper left beneath the tray platform after a previous jam — a torn sheet or fragment wedged beneath the platform physically prevents the platform from rising to the required height. The platform may lift partially but jam against the debris before PS116 is reached. This is common after a Tray 3 misfeed that was cleared without fully inspecting beneath the platform.
Tray 3 not fully seated in the cabinet — if the tray is not pushed fully to the rear stop, the lift mechanism may not engage correctly or the tray detection switch may not signal the PCCB to initiate the lift-up sequence. Always confirm the tray is fully closed before diagnosing any electrical component.
Loose or disconnected connector at M113 (PCCB CN6 or CN6C) — an open circuit on the M113 drive line means the PCCB attempts to run the motor but no drive signal reaches M113. The platform never moves and PS116 never actuates. This is often caused by vibration working the CN6 connector block loose over time.
Loose or disconnected connector on the PS116 signal path (PS116 → relay CN24 → PCCB CN4) — an open circuit on the sensor signal path means M113 may raise the platform correctly, PS116 may actuate physically, but the ON signal never reaches PCCB CN4-3. The PCCB times out waiting for confirmation and logs C0206. This is a common cause of intermittent C0206 on machines where the tray is frequently pulled in and out, working the relay connector CN24 progressively loose.
M113 lift-up motor drive coupling failure — if the coupling between M113 and the lift gear train has cracked, slipped, or seized, M113 may run electrically but fail to transmit torque to the lifting mechanism. The platform remains stationary and PS116 is never actuated.
Worn or damaged M113 lift gear train — the gear reduction train that converts M113’s rotation into platform lift movement can suffer worn teeth, cracked gear bodies, or foreign material ingestion that prevents or limits platform travel.
PS116 sensor contaminated, misaligned, or failed — the PS116 photo-interrupter can accumulate paper dust or toner on its emitter/receiver faces, preventing the optical beam from being interrupted even when the actuator flag enters the detection zone. The sensor can also be physically misaligned from the tray being repeatedly slammed in, or the sensor itself can fail electrically. A failed PS116 that is permanently in the OFF (unblocked) state will cause C0206 on every lift attempt even if the platform reaches the correct height.
Faulty PCCB — if the PCCB’s M113 drive output circuit or its PS116 input reading circuit has failed, either the motor will not run or the sensor signal will not be read correctly. PCCB failure is the least common cause of C0206 and should only be considered after all mechanical, connector, sensor, and motor causes have been eliminated.
Faulty MFPB — on some model families the MFPB provides a supply voltage or fuse protection circuit (e.g. MFPB F4E on PC-113/PC-213 models; MFPB F1E on PC-115/PC-215 models) that the PCCB depends on to power M113 or PS116. A blown fuse on the MFPB or a failed MFPB power output will deprive the cabinet of the supply needed for the lift motor, producing C0206 without any fault in M113, PS116, or the PCCB itself.

Step-by-Step Diagnostic and Repair Procedure

⚠️ Warning: Switch the machine OFF at the main power switch and disconnect the power cord before performing any connector checks, mechanical inspections, or component replacements inside the paper feed cabinet. The lift mechanism contains a motorized gear train that can cause injury if it starts unexpectedly. Do not place fingers under the tray platform when the machine is powered on. When performing sensor I/O checks or motor operation checks through service mode, ensure hands and tools are clear of all moving parts before initiating any load check.

Step 1 — Perform Initial Mechanical Checks Before Any Electrical Diagnosis

Pull Tray 3 fully out of the cabinet.
Check the paper fill level against the maximum fill indicator marked on the tray walls. If the stack exceeds this line, remove paper until the stack is at or below the maximum mark. Overfilling is the single most common cause of C0206 in office environments.
With the tray removed, visually inspect beneath the tray platform and within the tray housing for any torn paper fragments, staples, paper clips, or other debris that could obstruct the platform’s upward travel. Remove any debris found. Use a flashlight to inspect the full extent of the platform’s travel path — do not rely on a superficial visual check from above.
Inspect the paper itself. Damp, curled, or heavily recycled paper may fan out at the edges and catch on the tray walls during lift, stalling the platform before it reaches PS116. If the paper appears suspect, remove it and test with a fresh ream of standard-specification paper.
Push Tray 3 back into the cabinet firmly until it reaches the rear stop and the front face is flush with the cabinet panel. A tray that is not fully seated will either not trigger the lift sequence or will trigger it from a misaligned position that prevents PS116 actuation.
Reconnect power and observe whether the lift mechanism initiates and whether C0206 recurs. If the error clears, document the mechanical root cause (overfill, debris, or seating) and close.

Step 2 — Inspect and Reseat All Connectors in the M113 and PS116 Signal Paths

Power the machine OFF and disconnect the power cord.
Access the PCCB inside the paper feed cabinet per the cover removal procedure in the service manual for your specific cabinet model.
Locate the M113 motor connector at the PCCB:
- PC-110 / PC-210 / PC-113 / PC-213 models: PCCB CN6, pins 8 to 9 (M113 drive signal). Control signal location: wiring diagram 2-C for the applicable cabinet.
- PC-114 / PC-214 / PC-115 / PC-215 models: PCCB CN6C, pins 8 to 9. Control signal location: wiring diagram 2-C for the applicable cabinet.
Press the connector locking tab, fully withdraw the connector, and firmly reseat it until the locking tab clicks. Perform the same procedure at the motor-side connector on M113 itself.
Locate the PS116 sensor signal path connectors:
- The PS116 signal travels from the sensor body through an intermediate relay connector CN24 before reaching the PCCB at CN4 pin 3 (ON signal).
- Reseat the connector at PS116 (at the sensor body), at relay CN24, and at PCCB CN4. All three connection points must be secure for PS116’s signal to reach the PCCB reliably.
Inspect all connector pins in both signal paths for bent contacts, pushed-back pins, toner contamination, or corrosion. Clean with isopropyl alcohol and a soft brush if contamination is found. Do not use compressed air directly into connectors.
Reconnect power and insert Tray 3 with a correctly filled stack. Observe whether the lift-up sequence completes and C0206 clears. If resolved, document and close.

Step 3 — Inspect the M113 Drive Coupling and Lift Gear Train

Power the machine OFF and disconnect the power cord.
Remove Tray 3 from the cabinet.
Locate M113 and the drive coupling between the motor shaft and the lift gear train. Refer to the service manual for your cabinet model for the M113 location within the cabinet.
Inspect the drive coupling for cracks, deformation, or disengagement from either the motor shaft or the gear train input shaft. A plastic coupling that appears intact at rest may flex or skip under load — attempt to apply gentle torque by hand to confirm the coupling transfers force correctly in both directions.
Manually attempt to rotate the lift gear train — the mechanism that raises the platform — by hand through its full travel range. It should move with moderate resistance, smoothly, with no binding points or sudden seizure. Note any position in the gear rotation where resistance increases significantly, which may indicate a worn tooth, debris ingestion, or a bent component in the gear train.
Manually raise the Tray 3 platform by hand (with the tray removed from the cabinet) through its full travel range. The platform should move freely without catching. Confirm the platform can reach the full upper position without obstruction.
If a damaged coupling or a jammed gear train is found, refer to the service manual for the replacement part number and replacement procedure. Do not attempt to repair cracked plastic gears or couplings with adhesive — replace them.
After correcting any mechanical fault, reinstall the tray, reconnect power, and test. If C0206 clears, document and close.

Step 4 — Inspect and Test PS116 (Tray 3 Upper Limit Sensor)

Power the machine OFF and disconnect the power cord.
Locate PS116 within the cabinet. Refer to the service manual wiring diagram for your cabinet — PS116 is typically positioned at the height corresponding to the top-sheet feed position in the Tray 3 column, visible once the cabinet side panel is removed.
Inspect the PS116 sensor emitter and receiver faces for paper dust, toner buildup, or other contamination that could prevent the optical beam from being interrupted by the platform actuator flag. Clean the sensor faces with a dry lint-free cloth or a cotton swab. Do not use solvents on the sensor body.
Inspect the PS116 actuator flag (the physical flag or tab on the tray platform that enters the sensor beam when the platform reaches the upper limit position). Confirm the flag is:
- Present and not broken or bent.
- Aligned to enter the PS116 beam path correctly when the platform is at the upper limit position.
- Free to move through the beam path without catching on adjacent components.
With the connectors reseated from Step 2, reconnect power and perform the PS116 I/O check in service mode:
- Navigate to the I/O check function in Service Mode. Refer to the service manual for your model’s service mode navigation path.
- Monitor the PS116 signal at PCCB CN4-3 (ON). The signal should be OFF when the platform is in the lowered position (flag clear of the sensor beam) and should switch to ON when the platform actuator flag manually enters the sensor beam (simulate by slowly raising the platform by hand or by temporarily inserting a slip of paper into the sensor beam path).
- If the signal does not change state when the beam is interrupted, PS116 is either failed, contaminated, misaligned, or its harness to CN24 is open. Confirm the harness connections at PS116 → relay CN24 → PCCB CN4 are all seated before condemning the sensor.
If PS116 is confirmed faulty after harness verification, replace PS116. Refer to the service manual for the correct sensor part number for your cabinet model. After replacement, confirm the new sensor actuates correctly via the I/O check before closing the cabinet.

Step 5 — Perform the M113 Motor Operation Check via Service Mode

With all connectors confirmed seated and mechanical issues resolved, reconnect power and enter Service Mode.
Navigate to the motor operation check or load check function.
Execute the M113 check using the following parameters by cabinet generation:
- PC-115 / PC-215 (bizhub 458e/558e/658e, 308e/368e, C458/C558/C658): Check code: 23, Multi code: 6, Control signal: PCCB CN6C-8 to 9, Wiring diagram location: PC-115/PC-215 2-C.
- PC-113 / PC-213 (bizhub 227/287/367): M113 operation check, Control signal: PCCB CN6-8 to 9, Wiring diagram location: PC-113/PC-213 2-C. Refer to service manual for check code and multi code.
- PC-110 / PC-210 (bizhub C224/C284/C364 series and related): M113 operation check, Control signal: PCCB CN6-8 to 9, Wiring diagram location: PC-110/PC-210 2-C. Refer to service manual for check code and multi code.
- PC-114 / PC-214 (bizhub C227/C287/C367): Control signal: PCCB CN6C-8 to 9. Refer to service manual for check code, multi code, and wiring diagram reference.
During the operation check, observe and listen to M113. The motor should run smoothly and the platform should visibly begin to rise. An M113 that does not run at all, runs erratically, or stalls immediately under minimal load has a confirmed internal failure — proceed to Step 6.
If M113 runs correctly during the operation check but C0206 still appeared in normal operation, the fault is most likely a PS116 sensor or signal path issue — return to Step 4 and complete the PS116 I/O check if not already done.

Step 6 — Check MFPB Fuse Conduction

On several model families the MFPB provides a fuse-protected power supply that the PCCB depends on to drive M113 or power PS116. A blown fuse on the MFPB will prevent M113 from running regardless of the PCCB’s command, producing C0206 without any fault in M113 or PS116 themselves. Always check the MFPB fuse before replacing the PCCB or M113.

Power the machine OFF and disconnect the power cord.
Access the MFPB in the base machine. Refer to the service manual for your model’s MFPB location and access procedure.
Locate and test the relevant fuse:
- PC-113 / PC-213 models (bizhub 227/287/367 and related): Check MFPB F4E conduction. A blown F4E will prevent M113 from receiving its power supply from the MFPB.
- PC-115 / PC-215 models (bizhub 458e/558e/658e, 308e/368e and related): Check MFPB ICP1E conduction (bizhub 368e/308e) or MFPB F1E conduction (bizhub 658e/558e/458e).
- PC-110 / PC-210 models: Refer to service manual for the applicable MFPB fuse designation.
Test fuse conduction with a multimeter in continuity mode. A blown fuse will show open circuit (no continuity). If the fuse is blown, replace it with an identical rated fuse — do not substitute with a higher-rated fuse. After fuse replacement, investigate what caused the fuse to blow before returning the machine to service; a blown fuse is typically a symptom of a wiring short or a motor with shorted windings.
After confirming or restoring fuse integrity, retest the lift-up sequence from Tray 3 before proceeding to board replacement.

Step 7 — Replace M113 (Tray 3 Lift-Up Motor)

Power the machine OFF and disconnect the power cord.
Remove M113 from the cabinet per the motor removal procedure in the service manual. Note the motor mounting orientation, bracket configuration, and harness routing before removal.
Install the replacement M113, confirming:
- The motor shaft coupling engages correctly with the lift gear train input.
- All mounting screws are fitted and tightened.
- The motor harness is routed as in the original installation without pinch points.
Reconnect the M113 harness to PCCB CN6 or CN6C as applicable, confirming the connector is fully locked.
Reconnect power and perform the M113 operation check from Step 5 with the replacement motor before inserting the tray, to confirm electrical operation before any mechanical load is applied.
Insert Tray 3 with a correctly filled paper stack and confirm the lift-up sequence completes successfully with C0206 absent. Print a test page from Tray 3 to confirm end-to-end paper feed operation.

Step 8 — Replace the PCCB and/or MFPB

If a confirmed-good M113, a confirmed-good PS116, intact MFPB fuse conduction, and fully seated connectors throughout the signal paths all fail to resolve C0206, the fault is isolated to a board-level failure in the PCCB or MFPB. This is an uncommon scenario but does occur on machines with accumulated electrical stress or physical board damage.

Replace the PCCB first, as it directly drives M113 and reads PS116. Refer to the service manual for the board removal and installation procedure for your cabinet model. Photograph all connector positions before removal to ensure correct reinstallation on the replacement board.
After PCCB replacement, perform the M113 operation check and the PS116 I/O check to confirm the replacement board drives and reads both components correctly before inserting the tray for a test lift.
If replacing the PCCB does not resolve C0206, and the MFPB fuse conduction check from Step 6 showed a non-blown fuse but the MFPB supply output to the PCCB is suspect, replace the MFPB as a final step. Refer to the service manual for the MFPB removal procedure.
After any board replacement, perform a full Tray 3 test sequence — insert the tray, confirm lift-up, print a minimum of 20 continuous sheets from Tray 3 — before returning the machine to service.

Understanding the Tray Lift Error Family — C020x

C0206 belongs to the tray lift-up error group. Understanding the full family prevents confusion when multiple codes appear together or when the wrong tray’s code is reported:

C0202 — Tray 1 feeder up/down abnormality — Tray 1 upper limit sensor not actuated within timeout. Tray 1 is part of the base machine, not the optional cabinet; the lift motor and sensor are controlled by the PRCB (not the PCCB). Components: M12 (Tray 1 lift motor), PS22/PS25 depending on model (Tray 1 upper limit sensor), PRCB.
C0204 — Tray 2 feeder up/down abnormality — same logic as C0202 but for Tray 2. Tray 2 is also a base machine tray controlled by the PRCB. Components: M13 (Tray 2 lift motor), PS22/PS25, PRCB.
C0206 — Tray 3 lift-up failure — this article. Tray 3 is in the optional cabinet; controlled by PCCB. Components: M113, PS116, PCCB, MFPB.
C0208 — Tray 4 lift-up failure — same detection logic as C0206 but for Tray 4. Components: M123 (Tray 4 lift motor), PS126 (Tray 4 upper limit sensor), connected via relay CN47 to PCCB CN7, controlled by PCCB.

C0206 and C0208 appearing simultaneously suggests either a shared PCCB power supply fault, a PCCB failure affecting both lift circuits, or coincidental overloading of both trays — which is unusual. If both appear together, check the PCCB and MFPB supply circuits before investigating either tray’s lift mechanism individually.

C0206 appearing alongside C0106 (Tray 3 paper feed motor) or C0107 (Tray 3 vertical transport motor) suggests a PCCB connector block issue affecting multiple Tray 3 circuits simultaneously. Reseat all PCCB connectors before investigating individual motors or sensors.

Rank B Reset Procedure

C0206 is classified as Rank B. The machine halts and will not resume printing from Tray 3 until the fault is resolved. A main power off/on cycle may temporarily clear the error display if the lift mechanism successfully completes the lift-up sequence on the next attempt (for example, after paper was removed from beneath the platform), but C0206 will return immediately if the root cause remains present.

After completing the repair, power the machine OFF at the main power switch.
Wait at least 10 seconds for all internal circuits to discharge and the lift mechanism to fully reset to the lowered position.
Reload Tray 3 with a correctly filled paper stack — at or below the maximum fill line — using standard-specification, flat, undamaged paper.
Power the machine ON and observe the control panel. Listen for the sound of M113 initiating the lift-up sequence as the machine completes its startup routine.
Confirm that C0206 does not appear during startup or after the first Tray 3 feed attempt.
Print a minimum of 20 continuous sheets from Tray 3 at normal speed to validate stable lift operation and consistent paper feeding before returning the machine to service. An intermittent fault caused by a marginal connector contact or a borderline mechanical condition may only manifest after several feed cycles once the machine reaches operating temperature.

Preventive Maintenance Recommendations

Educate users on Tray 3 maximum fill capacity — overfilling is the most common cause of C0206 in office environments and is entirely preventable. The maximum fill line is marked on the tray walls. Remind users that the fill limit applies to all paper types and that heavier paper stocks (90 gsm and above) should be loaded to a lower level than standard 80 gsm copy paper, as the added weight increases lift load on M113.
Clean PS116 at every PM visit — paper dust and toner accumulate on PS116’s emitter and receiver faces progressively with every lift cycle. A sensor that is 70% contaminated may still function under good conditions but fail under thermal expansion or after cleaning fluid is introduced. A brief sensor face clean at every PM eliminates this gradual degradation.
Reseat PCCB CN6/CN6C and CN4 connectors at every PM on high-volume cabinets — on machines where Tray 3 is used as a primary paper source, M113 runs at every single print cycle. The cumulative vibration gradually loosens the CN6 motor connector and the CN4 sensor connector block. A 30-second connector reseat during PM is inexpensive insurance against an intermittent C0206 call between visits.
Inspect beneath the Tray 3 platform during every jam clearance visit — whenever a Tray 3 misfeed or jam is cleared, remove the tray and inspect beneath the platform before reloading. A paper fragment left beneath the platform during jam clearance is a very common trigger for C0206 on the next print job.
Inspect the M113 drive coupling and lift gear train during major PM — on machines where Tray 3 has accumulated high page counts, include a visual inspection of the M113 coupling and the lift gear train during major PM intervals. Catching a fatigued coupling or a worn gear tooth before full failure prevents an unplanned service call for C0206.
Check the MFPB fuse conduction during board-level PM — on models where the MFPB fuse (F4E, F1E, or ICP1E depending on model) protects the M113 supply, include a fuse conduction check during any PM that involves accessing the MFPB. A fuse that is at the edge of conduction may not be blown yet but can open under thermal load during high-volume printing.

Professional Technician Summary

Error Code C0206 on Konica Minolta bizhub machines fitted with a Tray 3 paper feed cabinet is a position-feedback fault, not a simple motor failure. The PCCB detected that PS116 — the Tray 3 upper limit sensor — did not confirm the paper stack reached the correct feed height within the allowed time after M113 was commanded to lift. This single code can be produced by mechanical overloading, debris obstruction, a loose connector, a contaminated sensor, a failed motor, a blown MFPB fuse, or a faulty PCCB — which is why the diagnostic sequence must be followed in order from the simplest mechanical checks outward to board replacement.

In the majority of field cases, C0206 is resolved without replacing any components: removing paper debris from beneath the platform, correcting an overfilled tray, reseating the M113 motor connector at PCCB CN6/CN6C, or cleaning PS116 accounts for most calls. When component replacement is required, M113 motor failure is more common than sensor failure, and PCCB or MFPB board failure is the least common outcome — reached only after all mechanical and connector causes have been definitively eliminated.

Always resolve the root cause rather than relying on power-cycle resets. A C0206 that clears on power cycle but recurs after a few print jobs invariably has an intermittent connector or marginally contaminated sensor that will become a hard fault within a short time if not properly addressed at first call.
