Number Of Sheets For An Offset Job - Canon SADDLE FINISHER K3 Service Manual

2.3.3 Number of sheets for an offset job

A stack is discharged when it has collected five sheets or three sheets (large-size). If the
number of sheets for a specific offset job cannot be divided by 5, the last stack falling short
of the full count will be discharged. However, the final stack must not contain 1 sheet (e.g.,
if 5n+1, the last stack will contain one sheet.) In such a case, the second stack from the last
will be discharged containing four sheets to avoid discharging a single sheet. In the example,
the above stack will consist of two sheets.
E.g.
1. For eight small-size sheets, the combination will be a 5-sheet stack and a 3-sheet stack.
2. For ten small-size sheets, the combination will be a 5-sheet stack and a 5-sheet stack.
3. For 16 small-size sheets, the combination will be a 5-sheet stack, 5-sheet stack, 4-sheet
stack, and a 2-sheet stack.
Why Avoid a Single-Sheet Stack?
A single sheet of paper will not follow a fixed trajectory from the stack de-
livery slot to the top of the existing stacks in the sort tray, resulting in cases
Memo
where the stack jogging is disrupted. In order to prevent this from happen-
ing, stacks contain two or more sheets to stabilize the drop trajectory.
Large size sheets are delivered in stacks of three. If the last stack consists of 1 sheet, it
will be combined with the previous stack, thus forming a 4-sheet stack.
