Page 498 4.Troubleshooting: Post-Processing Option Cause When binding with staples, to save time in adjusting the bundle of paper in the staple tray, the paper is held temporarily (pre-stack) prior to release to the staple tray. For that reason, paper is stacked on top of each other at the paper exit to the staple tray, and due to the structure of the pre-stack, the leading edge of paper is misaligned from the sheet transported before it by about 5mm when it is discharged to the staple tray.

Trailing Edge of Stapled Sheets Close to the Paper Exit Cause If the stapled sheets are curled strongly or become limp after delivery, the trailing edge of the sheets may be too close to the paper exit when the paper is stacked.
Page 500 4.Troubleshooting: Post-Processing Option Leading edge 4mm pitch edges getting dirty Cause When the back curl correction (straightening paper which is curled face down) is enabled, nip the paper with sponge roller (upper) [A] and metal roller (lower) [B].

Page 505 4.Troubleshooting: Post-Processing Option Cause During binding processes (edge stapling, saddle stitching), paper is transported to and assembled in a staple tray and then it is discharged by a release claw. When discharging thin, coated paper, if the paper is weak-bodied, short-grained paper, as the mechanism tries to push and lift up the trailing edge of the paper, it makes it buckle, resulting in scratches on the paper and/or jams due to failure to release.

Page 515 4.Troubleshooting: Post-Processing Option Folds Soiled by Multi-Sheet Folding Cause If multi-sheet folding is performed after a large number of Z-folds have been performed, the tip of the blade used for the multi-sheet folding may be soiled [A], resulting in soiled paper. This will produce paper soil of 1-3 cm (0.4-1.2 inches) in width (equal to the width of the blade) in the fold in the center of paper.
