CHAPTER 2 FINISHER UNIT BASIC OPERATION
2. First Sheet
The finisher controller PCB stops the delivery motor (M2) as soon as the trailing edge of the
first sheet has moved past the delivery roller. Then, it rotates the delivery motor clockwise to switch
the gear drive to the swing guide mechanism, causing the swing guide to move up. When the swing
guide open sensor (PI18) finds the swing guide in up position, the delivery motor stops, thereby
maintaining the swing guide in up position.
When the swing guide has moved up, the feed belts of the feed roller 2 move the sheet to the
stapling tray. The presence of paper on the stapling tray is detected by the stapling tray paper sensor
(PI4).
The finisher controller PCB drives the alignment plate shift motor (M3) when the stapling tray
paper sensor has detected paper to put sheets in order. The alignment plate is kept in wait in advance
at a point 10 mm behind the trailing edge of the paper.
The swing guide is kept in wait in up position until the last sheet is deposited on the stapling
tray.
