2) Details of operation
1
The alignment plate and the rear edge plate detect the home
positions, and moves to the paper size position. (ADU motor 1, 2,
ON)
2
Paper exit, reverse unit operation (ADU gate solenoid ON)
3
Rollers in the ADU rotate in the direction of paper entry. (ADU
drive motor ON)
4
ADU paper entry detection (ADU paper entry/exit sensors 1, 2
ON)
5
ADU paper presence detection (ADU paper sensors 1, 2 ON)
(
5
-1 is used only in the AB series.)
6
Rollers in the ADU rotate in the direction of paper exit. (ADU drive
motor ON)
7
Holding plate operation (Take-up clutch ON)
8
Take-up roller. paper feed roller rotation (Paper feed clutch ON)
9
ADU paper feed detection (ADU paper entry, exit sensor ON)
F
ADU paper transport detection (ADU transport sensor ON)
