CHAPTER 2 FINISHER UNIT BASIC OPERATION
3. Second and Subsequent Sheets
The finisher controller PCB turns on the belt escape solenoid (SL7) before the trailing edge of
the second and subsequent sheets have moved past the feed roller 2 to make the knurled belt escape.
This operation is performed to reduce the time it takes for the trailing edge of the paper to fall on the
stapling tray, and to improve the product duty. The finisher controller PCB turns on the paddle
solenoid (SL5) as soon as the trailing edge of the second and subsequent sheets have moved past the
feed roller 2, causing the drive of the second feed motor (M8) to rotate the paddle. The sheets are
pushed by the paddle and moved to the stapling tray. Almost simultaneously with the trailing edge
of the sheet falling into the stapling tray, the belt escape solenoid turns off to return the knurled belts
that were in the escape position to its original position, and feed the sheet onto the stapling tray.
When the sheet has been output onto the stapling tray, the finisher controller PCB rotates the align-
ment motor (M3) to put the sheets in order.
