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 sole-
noid (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 alignment motor
(M3) to put the sheets in order.

Last Sheet
When the last sheet has been put in order, the finisher controller PCB turns on the alignment
motor (M3) to move the alignment plate to the alignment position (to butt the plate against the stack).
Then, the finisher controller PCB rotates the swing motor (M7) counterclockwise to move down the
swing guide.
Then, the finisher controller PCB rotates the swing motor (M7) counterclockwise to move down the
swing guide.
The finisher controller PCB moves the stapler according to the staple mode for stapling.
From then on, it rotates the delivery motor (M2) clockwise to deliver the stack to the tray.
