When bundle to be bound is poorly aligned
If there is a lot of friction between sheets of paper, as happens with coated paper, during pre-stacking, the alignment of leading edge stopper fails to correct the misalignment of paper, so it is not stapled neatly.
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.
Solution
Select “Adjustment Settings for Skilled Operators” of 0606: [Number of Sheet Align for Stapling]( SP6-225-001 to 014), and set the value lower than current value.
Productivity may suffer from reducing the number of sheets in the pre-stack.
