Operation - Canon NP6330 Service Manual

2. Operation

1) When the Copy Start key is pressed for the first side of a two-sided copy (auto mode)
the horizontal registration solenoid (SL7) turns on, and the horizontal registration
motor (M5) rotates to move the horizontal registration paper edge sensor (PS16) to
suit the size of the copy paper used.
Reference:
The horizontal registration paper edge sensor (PS16) moves to the center of the
feeding path (i. e. the position that PS16 has detected the light-blocking plate.)
when the power switch is turned, and moves to suit the width of paper when two-
sided copying starts. It moves from its previous position if a different size paper is
used.

2) When the Copy Start key is pressed for the second side copy, the horizontal
registration motor (M5) starts to rotate to move the horizontal registration roller to
home position. (The home position of the horizontal registration roller is where the
actuator has moved past the horizontal registration roller home position sensor
PS15.)
