Stapler
The stapler consists of the staple cartridge and the stapler assembly. The staple cartridge holds up to 5,000
staples. The staple presence sensor detects the presence of staple. The staple ready sensor detects whether
the stapler is in the correct position to staple. The staple assembly is equipped with the stapler motor. When
the stapler/stacker controller rotates the stapler motor, the staple arm lowers and staple operation begins.
The stapler sensor detects the position of the staple arm.

Stapler/Stacker controller
The stapler/stacker controller determines a stapler motor failure and notifies the formatter through the DC
controller when it does not detect the stapler sensor for a specified period after the stapler motor starts
rotating. The stapler/stacker controller determines a stapler jam and notifies the formatter through the DC
controller if it senses the stapler sensor after a specified period of time from when the stapler motor starts
rotating and then if the stapler sensor recovers within a specified period of time from when the stapler motor
is reversed.
