The paper transport motor (FPTM) is driven at the speed same
as the paper delivery speed of the main unit, and paper dis-
charged from the main unit is received.

When the paper rear edge passes the delivery roller of the
main unit, the paper transport motor (FPTM) is accelerated to
500mm/sec. At the same time, the paper alignment motor F
(FPAM-F) and the paper alignment motor R (FPAM-R) are
driven to put the paper alignment plate in the standby mode
outside of the paper width. In addition, the rear edge take-up
roller solenoid (FARLS) is turned OFF to lower the rear edge
