Mechanical System; Adjusting The Inserter Pickup Tray Horizontal Registration - Canon SADDLE FINISHER K3 Service Manual

1.2 Mechanical System

1.2.1 Adjusting the Inserter Pickup Tray Horizontal Registration

If the pickup tray on the inserter is displaced appreciably to the front or the rear, the
saddle stitcher assembly can fail to align sheets from the inserter. As a result, the sheet will
be stitched, folded, and delivered without alignment in relation to its host stack. This is es-
pecially true of the following:
• The inserter sheet is thick.
• The inserter sheet is not a copy.
• The stack consists of 15 sheets or so.
a. Symptom
a-1 If the inserter pickup tray is displaced to the front (misalignment 1),
1) The inserter sheet arrives at the saddle unit toward the front in relation to the existing
stack.
2) Of the two aligning plates of the saddle stitcher, the one at the front comes into contact
with the inserter sheet. The inserter sheet is held down by the feed path and is turned.
3) The inserter sheet and its host stack are stitched and folded white remaining out of
alignment (referred to as misalignment 1).
The inner pickup tray is
toward the front.
