• Description: Finisher delay jam at booklet-making paperentry sensor (PI22) Occurs when booklet making function is selected and after the engine signals the finisher that it is delivering paper to the finisher. The booklet-making-paper entry sensor (PI22) is not activated within the expected time period after receiving the engine's delivery signal, suggesting that a paper jam has occurred somewhere between the output accessory bridge (IPTU) and sensor PI22.
• Remedy: Control panel diagnostics: M9 (inlet motor), SL5 (inlet-switch solenoid) Signal generated from: PI22 (bookletmaking- paper entry sensor) Open the IPTU and the finisher top door and locate the media jam. Check the following items: • If media is found in the IPTU but has not reached the finisher entrance point, perform the following steps: • Remove and then reinstall the IPTU. Make sure that the connector is fully seated and that the IPTU is securely fastened. • If the error persists, replace the IPTU. • If media is jammed at the entrance point of the finisher, perform the following steps: • Verify that the finisher is securely fastened to the engine. • Make sure that the finisher and IPTU are correctly aligned. Adjust the finisher castors to obtain a uniform gap between the finisher and the engine• The engine-tofinisher gap must be the same at the bottom and the top so that the finisher is parallel to the engine. With the engine-to-finisher gap correct, make sure that the finisher paper path entry point is aligned with the IPTU exit point. • Check the finisher entry point guides for damage. • Verify that the finisher rollers are turning before the media leaves the IPTU. If the rollers are not turning, test motor M9 by using the finisher component test from the controlpanel display. If the motor does not activate during the test, check the connectors for motor M9 (inlet motor). Make sure that connector J705 is fully seated on the stacker controller PCA. If the error persists, replace motor M9 or the saddle paper-feeder assembly for the type finisher you are working on. Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA. • If media is found in the finisher but has not reached sensor PI22, perform the following steps: • Check the upper and lower guides and rollers in the paper path for damage. • Make sure that the media diverter gate (saddle-stitch flapper) is functioning properly. • Test solenoid SL5 (inlet-switch solenoid) by using the finisher component test from the controlpanel display. SL5 should be opening and closing the media diverter gate (saddle stitch flapper) • If media is found in the finisher cover sensor PI22 (the sensor is not detecting the media), perform the following steps: • Check the sensor for obstructions. Verify that the sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. Make sure that the lower end of the flag is not damaged and is correctly positioned to activate the sensor. • Make sure that the sensor is securely fastened to the chassis. • Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. • Verify that the wiring at the sensor is not damaged and that the intermediate connectors between the sensor and connector J21 on the saddle-stitcher controller PCA are fully seated. Replace the sensor if necessary. If PI22 is determined to be the failure point, replace the saddle paper-feeder assembly, which includes PI22. • Only if the error persists and the previous steps fail to correct the problem, replace the saddlestitcher controller PCA.

• Description: Finisher stay jam at booklet-making paper entry sensor (PI22) Occurs when the booklet-making paper entry sensor (PI22) remains activated longer than expected, suggesting that there is a paper jam at the sensor.
• Remedy: Control panel diagnostics: none 1. Remove any media in the upper paper path that might be activating sensor PI22. 2. Verify that the sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. 3. Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. 4. Verify that the wiring at the sensor is not damaged. Check the intermediate connectors between sensor PI22 and connector J21 on saddle-stitcher controller PCA for damage and proper connections. Replace the sensor if necessary.

• Description: Finisher delay jam at booklet making first paper sensor (PI18) Occurs when the first-paper sensor (PI18) is not activated within the expected time following the activation of the bookletmaking- paper entry sensor (PI22), suggesting that there is a paper jam in the area between PI22 and PI18.
• Remedy: Control panel diagnostics: M1 (Delivery Motor) Open the IPTU and the finisher top door and locate the media jam. Check the following items: • If media is found at sensor PI18, perform the following steps: • Check the sensor PI18 for damage. Replace the sensor if necessary. • Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. • Verify that the wiring from sensor PI18 to connector J10 on the saddle-stitcher controller PCA is undamaged and the connectors are fully seated. • If media is found at the roller prior to sensor PI18 in the paper path, perform the following steps: • Test motor M1 (delivery motor) by using the finisher component test from the control-panel display. • Remove the finisher rear cover. Activate motor M1 and verify that the drive gears and belts are moving. • If motor M1 does not rotate, verify that connector J5 on the saddlestitcher controller PCA is fully seated. If the error persists, replace motor M1. If motor M1 still does not rotate, replace the saddle-stitcher controller PCA. • If motor M1 does rotate but the gears and belts connected to motor M1 do not move, check for damaged components. Replace damaged components as necessary.

• Description: Finisher stay jam at booklet making first paper sensor (PI18), flapper-1 paper sensor (PI19) or flapper-2 paper sensor (PI20) Occurs when PI18, PI19 or PI20 remain activated longer than expected, suggesting that there is a paper jam in the flapper 1 and 2 area of the booklet-maker section of the finisher.
• Remedy: Control-panel diagnostics: PI19 (flapper 1), PI20 (flapper 2), M1 (delivery motor), SL1 (flapper 1 solenoid), SL2 (flapper 2 solenoid) 1. Remove any media in the area around flapper 1 and flapper 2. 2. Check the flappers for damage. 3. Test sensor PI19 and sensor PI20 by using the finisher component test from the control-panel display. • If the sensors are faulty, perform the following steps: • Verify that the sensor flags are not damaged, move freely, and are correctly aligned with the sensor bodies. • Verify that the wiring at the sensors is not damaged and that the connector J10 on the saddle-stitcher controller PCA is fully seated. • If the error persist, replace the paper sensor PCA (which contains PI118, PI119, and PI20). 4. Test flapper 1 and flapper 2 by using the finisher component test from the controlpanel display. NOTE: To verify the proper movement of the flappers, activate SL1 and SL2 in the finisher component test.

• Description: Finisher jam: door was opened during booklet-making operation. Occurs while the machine is booklet making and the booklet delivery door sensor (PI3) or the booklet paper path open/close sensor (PI3) detects that the door or paper path has been opened. Also occurs when the finisher's front-door sensor (PI32) has been opened with paper remaining in the processing tray of the main stapler while the finisher is not operating.
• Remedy: Control-panel diagnostics: PI31 (top-door sensor), PI32 (front-door sensor), PI3 (booklet door 1 sensor) (booklet-delivery door) 1. Test sensor PI31, sensor PI32, and sensor PI3 by using the finisher component test from the control-panel display. 2. Make sure that the front door, top door, and booklet-delivery door properly open and close and stay in the fully closed position. If the front door is not closing tightly at the top, it will not activate the door switch. If necessary, adjust the alignment of the front door by opening the door and carefully twisting it into proper alignment. 3. Verify that the sensor-activation arms on the doors are not damaged. 4. Make sure that the sensors and frontdoor switch MSW31 are not obstructed. 5. Make sure that the arm on switch MSW31 is not bent or damaged. 6. Make sure that sensors PI31, PI32, PI9, and switch MSW31 are securely fastened to the chassis. 7. Only if the error persists and the previous steps fail to correct the problem, replace the stacker controller PCA.
