C. Stapler unit drive system
(1) Outline
The stapler unit staples paper discharged into the bins.
The stapling is driven by the stapler motor (M5).
The stapler unit oscillation is performed by the stapler unit oscillation
motor (M4).
The stapler unit home position is detected by the stapler unit oscilla-
tion home position switch (MS4) and the stepping motor is driven by
the specified number of pulses to move the stapler unit to the oscilla-
tion position.
During oscillation, the stapler presses the paper holding lever to hold
paper during stapling.
