Table 7-4 Control-panel messages (continued) Control panel message Description Recommended action finisher), associated gears, and the paper-pushing plate for proper motion. ◦ If motor M8 does not rotate, replace the motor-mount assembly. NOTE: The motor-mount assembly includes the paperpushing-plate motor M8. ◦ If motor M8 does rotate but the paper-pushing plate does not move or moves erratically, check the drive gears and paper-pushing plate for wear or damage. Replace components as necessary. ◦ If motor M8 does rotate and the paper-pushing plate moves properly, the plate movement sensors might have failed. ● Inspect the paper-pushingplate home-position sensor PI14, pushing-plate leadingedge-position sensor PI15, and paper-pushing-motor clock sensor PI1. Make sure that the sensors are securely fastened to the chassis. Check sensor PI4, sensor PI15, and sensor PI1 for damage. ● Verify that connectors J6, J9, and J23 on the saddlestitcher controller PCA are fully seated and not damaged. Check the wiring at the sensors. ● Only if the error persists and none of the previous steps correct the problem, replace the saddle-stitcher controller PCA. See Saddle-stitcher controller PCA (booklet maker only) on page 827. ENWW Control-panel messages 491
