Table 7-4 Control-panel messages (continued) Control panel message Description Recommended action the front frame of the finisher, above the main stapler unit. 1. Remove any media in the upper paper path that might be activating sensor PI34. 2. Carefully clean the sensor body, by gently blowing clean air across the sensor to remove dust and debris. 3. Verify that the sensor flag is not damaged, moves freely, and is correctly aligned with the sensor body. 4. Lift-swing-guide assembly at the paper exit area to output bins and inspect for jammed paper, obstructions, or damage. 5. Run a diagnostic through the engine control panel and turn on M31 (entrance motor) to observe gear rotations on the upper-rear frame of the finisher. Ensure that the first delivery rollers and buffer rollers that pass paper to and from PI34 are rotating. 6. Test SL32 (buffer-roller solenoid) and SL33 (output-roller solenoid) using the control-panel diagnostics. 7. Check wiring from sensor PI34 to stacker-control-board connector J707 for damage. 8. 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. 13.12.16 Finisher jam - door opened during Staple/ Stacking operation Control-panel diagnostics: PI31 (top-door sensor), PI32 (front-door sensor) While the machine is printing, the upper-door (open/close) sensor (PI31) or front-door (open/close) sensor (PI32) or the front-door (open/close) switch (MSW31) has signaled that one of the doors has been opened, suggesting that there may now be paper found in the upper paper path. Booklet maker only: check PI3 (bookletdoor-1 sensor) (booklet-delivery door) 1. Make sure that the doors 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. 2. Verify that the sensor-activation arms on the doors are not damaged. 3. Make sure that the front-door sensor PI32 and switch MSW31 and top-door sensor PI31 are not obstructed. 446 Chapter 7 Solve problems ENWW
