11. STAPLER UNIT
11.1 STAPLER UNIT DRIVE MECHANISM
The stapler unit moves from the home position (top slant position) towards
the rear of the machine in order to change the stapling position. The stapler
unit HP sensor [A] activates when the stapler unit is in the home position.
In Top Slant mode, the stapler stays at the home position.
In "Top" ("Bottom") single staple mode, the stapler unit moves to the front
(rear) single staple position and stays there until all stapling is completed. It
then returns to the home position.
In "2 Staples" mode or "Bottom" single staple mode, the stapling positions
depend on the paper size. The stapler unit drive motor [B] is a stepper motor,
and the stapling position is reached by counting the steps from the home
position. During stapling in the "2 Staples" mode, the stapler unit goes back
and forth to staple the two positions.
Horizontal stapling positions can be adjusted by changing the number of
stepper motor pulses from the home position (see the SP mode table,
SP6-105-002).
