• Sensor (punch waste box set)
– A photo-interrupter sensor that detects whether the waste box is properly set.
– When the punch waste box is properly set, the actuator of the box blocks the light transmission of the
sensor, which turns the sensor to high (+5 V dc).
• Sensor (punch waste box full)
A photo-interrupter sensor that detects whether the punch waste box is filled with punch waste.
Compiler unit assembly
This section describes the operation of the compiler unit assembly which aligns the media edge transferred from
the punch unit.
Outline of operation
When media is fed onto the compiler unit assembly, tamping is performed to align the media edge in the media
width direction.
When ejecting stapled sets of media to the stacker media bin, if they are stacked in the stacker media bin with
the same staple position, the height of the stapled portion will increase. This will cause improper compiling of
media due to butting of the following media. To prevent such improper compiling, offsetting is required by
shifting the staple position between sets of media.
