Description:
Finisher stay jam at either PI33 or PI34 when engine powered on. When the engine is powered on, the finisher's upper-feed-path-entry sensor (PI33) or the upper-feed-path-exit sensor (PI34) is activated suggesting that there is paper in the upper paper path of the finisher at sensors PI33 or PI34.
Remedy:
Signal generated from PI33 (upper-feedpath- entry sensor) and PI34 (upper-feedpath- exit sensor) 1. Open the top door and remove any media in the paper path (media detected at PI33). 2. Raise the upper paper path (exit) delivery rollers and remove any media in the paper path (media detected at PI34). 3. Check these sensors for obstructions. Verify that the sensor flags are not damaged, move freely, and are correctly aligned with the sensor body and properly mounted. Also check wiring and connectors for damage or loose connections. 4. Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. 5. Verify that the sensor connectors (J708 and J707) are fully seated on the stacker controller PCA. 6. Replace sensor PI33 and PI34. 7. Only if the error persists, replace the stacker controller PCA.

Description:
Finisher delay jam at PI33. The engine signals the finisher that paper is about to enter the finisher from the IPTU. The finisher's upper-feed-path-entry sensor (PI33), which detects paper entering the finisher, does not detect the paper within the expected time period triggering the error.
Remedy:
Open the IPTU and the finisher top door and check the following items: • If media is found in the IPTU but has not reached the finisher, 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 exit point of the IPTU (prior to entering 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 control-panel 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. Replace the stacker controller PCA. • If media is found in the finisher-covering sensor PI33 (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 connector J1007 and connector J708 on the stacker controller PCA are fully seated. Replace the sensor if necessary. • Only if the error persists, replace the stacker controller PCA.
