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.
