Reversing And Duplex Pick-Up Operation - Canon CLBR 460ps Service Manual

B. Reversing and Duplex Pick-up Operation
1. Outline
The print paper is guided to the duplexing unit with a face-up deflector. The deflector is oper-
ated with the face-up tray. When the face-up tray is closed, the deflector is operated by the
delivery deflector solenoid (SL3102).
The paper fed into the duplexing unit is reversed by changing the feed direction with the
reversing roller. Then, the paper is fed into the printer by the the duplexing unit feed roller after
the side registration (refer to Page 2-104) is adjusted by the side registration guide.
The reversing roller is rotated clockwise or counter clockwise by the reversing motor (M3102).
The duplexing feed motor (M3101) drives the duplexing unit feed roller. The side registration
motor (M3103) moves the side registration guide to the position corresponding the size of paper
which is fed into the duplexing unit. These motors are stepping motors and the rotations are
controlled by the duplex driver PCB.
