Re-Pickup From The Duplexing Unit; Operations - Canon CLC 1120 Service Manual

CHAPTER 7 PICK-UP / FEEDING SYSTEM
E. Re-Pickup from the Duplexing Unit

1. Operations

When copying on the second side of a double-sided copy, pickup will be from the stack of copy
paper on the duplexing tray.
The duplexing feed roller is lowered to prevent skew movement during re-pickup in response to
a press on the Copy Start key or after copying on the first side, and the paper jogging guide plate is
moved to a point 0.5 mm from copy paper.
Then, the stopper plate solenoid (SL12) turns off, and the stopper plate shifts down. When the
duplexing paper feed clutch (CL14) and the re-pickup clutch (CL15) turn on, the duplexing paper
feed roller and the duplexing separation/feed roller start to rotate by the drive of the duplexing motor
(M14) and the re-pickup motor (PM13), respectively, to move the copy paper to the pickup vertical
path assembly.
After re-pickup, the duplexing paper feed roller solenoid (SL13) turns on, and the duplexing
paper feed roller moves away from the surface of the paper.
