Table 7-4 Control-panel messages (continued) Control panel message Description Recommended action Finisher's upper-feed-path-entry sensor (PI33) is remaining activated longer than expected, suggesting that paper has jammed at the sensor. To locate this sensor, see Detect jams in the stacker unit on page 726. 1. Remove any media in the upper paper path that might be activating sensor PI33. 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. 13.12.14 Finisher delay jam at PI34. 4. Verify that the wiring at the sensor is not damaged and that the connector J708 on the stacker controller PCA is fully seated. Control-panel diagnostics: none Upper-paper-path-entry sensor (PI33) has signaled that paper has passed but upperpaper-path-exit sensor PI34 does not actuate within the expected time, suggesting that the paper has jammed between PI33 and PI34 in the upper paper path. To locate these sensors, see Detect jams in the stacker unit on page 726. 1. Remove any media jammed in the upper paper path between sensor PI33 and sensor PI34. 2. Check the paper path between sensor PI33 and sensor PI34 for obstructions that may be preventing the media from reaching PI34. 3. Verify that the PI34 sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. 4. Make sure that sensor PI34 is securely fastened to the chassis and wiring is properly connected to sensor. NOTE: Sensor PI34 is located on the front frame of the finisher, directly over the primary stapler. 5. Verify that the wiring at the sensor is not damaged and that the connector J707 on the stacker controller PCA is fully seated. 6. Only if the error persists and none of the previous steps correct the problem, replace the stacker controller PCA. See Stacker controller PCA on page 828. 13.12.15 Finisher stay jam at PI34 Finisher's upper-paper-path-exit sensor (PI34) remains activated longer than expected suggesting that paper has jammed at the sensor. Control-panel diagnostics: M31 (entrance motor), SL32 (buffer-roller solenoid), and SL33 (output-roller solenoid) To locate this sensor, see Detect jams in the stacker unit on page 726. PI34 is located on ENWW Control-panel messages 445
