Also check the wiring at sensor PI39. ◦ Replace the operation-tray assembly (processing tray). See Positioning plate unit (inner sideplate assembly) (booklet maker only) on page 791. ◦ 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. 66.12.14 Finisher stapling and offsetting front-aligningplate motor failure In order to neatly align the paper stack for either stapling or offsetting to take place, the front and rear aligning plates move to align each sheet when it enters the processing tray. The error occurs when the aligning plate either does not leave or when it does not return to the aligning-plate front-homeposition sensor (PI36) when the frontaligning-plate motor (M33) has been driven for 4 seconds.
