 The transfer timing sensor [A] detects the leading edge to start
sub scan registration.
 Based on the sensor detection timing, the speed of the transfer
timing motor [B] is increased or decreased to adjust the rotation
speed of the transfer timing rollers [C]. These rollers then feed
the paper to the PTR unit so that the image is positioned correctly
on the paper in the sub scan direction.
