2.8 STAPLER UNIT MOVEMENT
The machine has only one stapler [A]. It does stapling for booklets and for corner stapling.
The stapler unit motor [B] moves the stapler from side to side. The stapler unit HP sensor
[C] detects when the stapler unit is at home position.
In corner staple mode, at the start of the job, the stapler moves to the position where the
stapler will be inserted.
In booklet mode, at the start of a job, the stapler moves to a starting position that depends
on the paper size, as follows:
8.5 x 14 inches or shorter: Rear side staple position
Longer than 8.5 x 14 inches: Center position. When the stapler is at the center
position, bracket [E] releases ‘stopper L’, which catches the bottom edge of the
paper for booklet stapling with longer paper sizes. This will be described in a later
section.
If the stapler safety sensor [D] detects the stapler unit at its initialization, the stapler unit
stops moving until the stack feed out belt pawl and stopper S are at home position. If the
stapler unit does not stop, it could collide with the pawl and/or the stopper.
