• Description: Finisher-to-engine communication error The communication between the print engine and the finisher has been interrupted or lost.
• Remedy: Control panel diagnostics: none 1. Verify that the latest firmware updates are installed for the engine and finisher. 2. Make sure that the finisher is properly grounded. • Ensure that the finisher is latched and locked to the engine by tightening the thumbscrew inside the front door. • Ensure that the grounding-frame assembly (the bar with the wheel located between the engine and the finisher) is in the down position with the wheel touching the floor and that the grounding plate is not damaged. NOTE: The grounding-frame assembly is in the up position when the finisher is shipped. It must be lowered when the finisher is installed. 3. Make sure that the communication cable from the engine to the finisher is correctly installed. 4. Verify that connectors J701 and J726 on the stacker controller PCA are fully seated and not damaged. 5. Remove and inspect the electrical connections for damage and then reinstall the IPTU. Make sure that the connector is fully seated and that the IPTU is securely fastened. 6. If the error persists, replace the IPTU. 7. Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA.

• Description: Finisher error: swing motor (M36) and the swing-guide home-position sensor (PI35) Occurs when the swing guide does not leave its home position (swing-guide home-position sensor: PI35) after the swing motor (M36) is activated for 3 seconds. Also occurs when the swing guide does not return to its home position (swing-guide home-position sensor: PI35) after the swing motor (M36) is activated for 3 seconds.
• Remedy: Control panel diagnostics: M36 (Swing Motor) and PI35 (Swing Guide Home Position Sensor) 1. Test the swing motor M36 by using the finisher component test from the controlpanel display. NOTE: When activated during the component test, the motor should rotate for about five seconds. While the motor is rotating, make sure that the swing guide is moving up or down at the exit area for stapling and stacking. • If the swing guide freely moves up and down, proceed to the next step (testing the swing-guide sensor PI35). • If the swing guide does not freely move up and down, remove the finisher rear cover and use your hand to turn the gear located to the right of motor M36 clockwise. • If the swing guide moves upward, the gears are properly working. Replace motor M36. If after replacing the motor the motor still does not turn on, replace the stacker controller PCA. • If the swing guide does not move, inspect the gears and replace damaged components as necessary. 2. Test the swing-guide sensor PI35 by using the finisher component test from the control-panel display. NOTE: Manually lift the swing guide to the highest position, and then look at the control-panel display and verify a change in state for the sensor. • If the sensor state does not change, perform the following steps: • Verify that the connector J707 on the stacker controller PCA is fully seated and not damaged. • Manually activate the sensor PI35 at the sensor body. If the control panel does not indicate a change of state, replace the sensor. • If raising the swing guide does not activate the sensor but it can be manually activated at the sensor body, replace the swing-guide assembly. • If the PI35 sensor state does change, check the drive gears for damage or obstructions. Replace components as necessary.

• Description: Finisher error - shutter movement malfunction Normal operation: When the shutter clutch (CL31) and stack ejection lower roller clutch (CL32) are on, the shutter moves up (closed) when the stack ejection motor (M32) turns forward and moves down (open, delivery enabled) when the motor turns backwards. Error occurs when the shutter home position sensor (PI45) indicates no change when the stack ejection motor (M32) is activated for 3 seconds, indicating that the shutter is not moving.
• Remedy: Control panel diagnostics: none 1. Inspect the shutter for damage. If the shutter cannot freely move, replace the shutter assembly. 2. Remove the lower guide (grate-shaped) and check sensor PI45 for damage. Make sure that the sensor is securely fastened to the chassis. 3. Check for proper alignment of the shutter mounted on the back of the grate-shaped lower guide and the lift mechanism on the finisher chassis. 4. Verify that connector J721 on the stacker controller PCA is fully seated and not damaged. 5. Check CL31 during operation, and verify that it is correctly functioning by activating prior to the error. Replace CL31 if necessary. 6. Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA.

• Description: Finisher error - stack trailing-edge motor (M39) In order to improve stacking performance when ejecting copies, a trailing edge assist guide is used in addition to the stack ejection roller to support the rear end of the stack during stack ejection. Error occurs when the stacker trailing-edge guide does not leave its home position (PI39) after the stack trailing-edge motor (M39) has been turned on for 3 seconds.
• Remedy: Control panel diagnostics: M39 process motor (stack trailing-edge assist motor) Test the swing motor M39 by using the finisher component test from the controlpanel display. • If the trailing-edge assist guide does not move, perform the following steps: • Verify that connector J722 on the stacker controller PCA is fully seated and not damaged. Also check the wiring at motor M39 and sensor PI39. • Replace the operation-tray assembly (processing tray). • Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA. • If the trailing-edge assist guide does move, perform the following steps: • Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. • Verify that the sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. • Verify that connector J722 on the stacker controller PCA is fully seated and not damaged. Also check the wiring at sensor PI39. • Replace the operation-tray assembly (processing tray).

• Description: Finisher stapling and offsetting front-aligningplate motor failure In order to neatly align the paper stack for either stapling or offsetting to take place, the front and rear-aligning plates move to align each sheet when it enters the processing tray. The error occurs when the aligning plate either does not leave or when it does not return to the aligning-plate front-homeposition sensor (PI36) when the frontaligning- plate motor (M33) has been driven for 4 seconds.
• Remedy: Control panel diagnostics: none 1. Verify that Offsetting is turned On in the Device Behavior menu. 2. Verify that connector J722 on the stacker controller PCA is fully seated and not damaged. Also check the wiring at sensor PI39 and motor M33. 3. Replace the operation-tray assembly (processing tray). 4. Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA.
