Table 7-4 Control-panel messages (continued) Control panel message Description Recommended action controller PCA. See Stacker controller PCA on page 737. ● If media is found in the finisher but has not reached sensor PI33, 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 not blocking the paper path. ● 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 and the previous steps fail to correct the problem, replace the stacker controller PCA. See Stacker controller PCA on page 737. 13.12.13 Finisher stay jam at PI33. Control panel diagnostics: none 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 636. 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. 360 Chapter 7 Solve problems ENWW
