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.
The paper is discharged to the staple tray and its leading edge is pressed against the leading edge
stopper, the paper is then aligned by the base fence pressing against the trailing edge; however, when
there is a great deal of friction between sheets, as happens with coated paper, the aligning effect of the
leading edge stopper fails to correct the misalignment.
Furthermore, when the paper is thin and weak-bodied, even the aligning effect of the leading edge
stopper may cause the paper to buckle and prevent correction.
This is likely to occur if:
When stapling paper with a great deal of friction between sheets, such as coated paper.
When stapling paper weak-bodied paper, such as thin paper.
