MX-7000N  PAPER TRANSPORT SECTION  G – 6

Paper is fed from each paper feed section and transported to the
resist roller by the transport rollers.
ON/OFF of each transport roller is controlled of by the paper trans-
port clutch.
The resist roller controls the relative positions of transported paper
and the transfer image.
The resist roller is driven by the transport motor.
The relative positions of paper and the transfer image are deter-
mined by the ON timing of the transport motor.

1)

Romove the front cabinet, the right lower door, and the right
lower door cover. (Refer to the "[A] EXTERNAL OUTFIT".)

2)
