STAPLING
B602 54 SM
3.5.3 POSITIONING
Action and Drive
There is one stapler [A] in the finisher. The stapler is on six rails [C][D][E][I]. The
rail [C], rail [D], rail [I], and rail [J] transmit the drive power:
• The rail [C] and rail [I] transmit the drive power of the stapler/folder motor.
The stapler uses this power to staple the paper (
!
3.5.2).
• The rails [D] and [J] transmit the drive power of the staple slide motor [H].
This drive power moves the stapler to the front or rear.
In the diagram above, [B] is the paper stack on the stack tray.
Home Position and Ready Position
The home position sensor [G] is at the bottom of the stapler; the sensor blade [F] is
on the frame of the unit. The controller references the home position sensor to set
the stapler in its ready position. Note that the stapler is not in the home position
when it is ready. The controller sets the stapler in the ready position as follows:
1. You turn the main switch on (or you close the front door of the finisher).
2. The slide motor drives the stapler from the rear side to the front side.
3. The home position sensor detects the sensor blade. The slide motor stops.
4. The slide motor starts in reverse to drive the stapler to the rear side. The
controller starts to count the pulses of the motor.
5. When the pulse count reaches a predefined number (not adjustable), the
controller stops the slide motor. The stapler is in its ready position.
