CHAPTER 2 OPERATIONS
2. Discharging Three Sheets
If three sheets have moved past the sort delivery roller from the buffer roller, the stack delivery
roller will rotate in reverse to send the stack of three sheets in the direction of the processing tray.
If the knurled belt moved the stack of three sheets, the force of feeding would be too strong that
the stack would bend against the stopper. To avoid such a problem, the knurled belt is released and
the stack delivery roller and the paddle operate to move the 3-sheet stacks to the processing tray.
1. The stack moves past the sort delivery roller. At the same time, the knurled belt solenoid turns on
to release the knurled belt.
