Shifting the Stapler Unit

The stapler unit is moved by the stapler shift motor (M4). Its home position is detected by the
stapler shift home position sensor (PI7). When the start signal arrives from the host machine, the
stapler moves to the center of its movement range. This movement occurs regardless of the selected
mode of delivery, as no specific mode is recognized at this point in time. When the command for
stapling arrives from the host machine after the first sheet has reached the host machine pre-regis-
tration sensor, the stapler moves to the staple wait position to suit the appropriate stapling position
and paper size.
See Figures 2-235 and later for an idea of the waiting position according to the stapling mode.
