CHAPTER 2 FINISHER UNIT BASIC OPERATION
3.

2nd 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 feed roller 2 to make the feed 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
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 is turned off to return the feed
belts that were in the escape position to their 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
alignment motor (M3) to put the sheets in order.
