The stapler unit of this machine is of the fixed type and it staples sheets of paper when the Staple mode is selected on the operationpanel on the main body. Since

this stapler unit is of the fixed type, it can staple sheets at one front position.This machine puts in staples from the bottom of paper.The following table lists the

components of the stapler.

A rough diagram of the staple motor (M5) drive circuit is shown below.

The staple motor is a DC motor.

The motor rotation direction can be changed by the combination of motor drive signals sent from the CPU (on the finisher controller PCB) to the motor drive circuit.

This machine has a 1-stage stack tray to which the paper aligned/offset/stapled in the process tray is ejected. When the first stack of paper is fed to the stack tray,

the stack tray paper presence sensor (PI8) is turned on.
