In any mode other than the front staple mode, the stapler moves to the specified position, and then performs
stapling.
Stapler unit assembly
The stapling operation is executed by closing the stapler unit assembly.
The stapler unit assembly, containing the staple motor, the sensor (staple home), the sensor (self priming), and
the sensor (low staple), is activated by the staple motor.
Forward (clockwise) rotation of the motor drives the stapler to staple a set of sheets, and returns the stapling unit
to the home position.
If stapling fails, the motor rotates reversely (counterclockwise) to return the stapler unit assembly to the home
position.
When staples become low, the low staple sensor detects it, and stapling stops automatically, displaying an
alarm message. The message is also displayed when the staple cartridge is not installed.
