Horizontal Registration Detection

1) About 150 msec after the lead edge of paper has moved past the inlet sensor (PS3), the
finisher controller PCB causes the horizontal registration detection unit shift motor (M6)
to rotate clockwise so that the horizontal registration sensor (UN12) moves to its standby
position (paper edge) from home position.

2) The finisher controller PCB causes M6 to rotate clockwise so that UN12 moves to
horizontal registration detection position (11 mm toward the inside from standby position),
during which UN12 detects the edge of paper to be moved. The finisher controller PCB
uses the results of the detection to compute the horizontal registration value.
