When the paper length exceeds 216mm, the sheets are dis-
charges at the same speed as the process speed.

B. Paper scrape and alignment
1)
For the first sheet of a bundle, the paper pass detector
(FPPD1) is turned ON and the delivery roller lift motor
(FDRLM) is driven to lower the bundle exit roller. The paper
delivery motor (FPDM) is driven at the paper exit speed of the
main unit to drive the bundle exit roller.
In addition, the paper alignment motor F (FPAM_F) and the
paper alignment motor R (FPAM_R) are driven by turning ON
the paper pass detector (FPPD1) to shift the alignment plate to
15mm outside the paper, and enter the standby state. After
transport of a certain amount, the delivery roller lift motor
(FDRLM) is driven to lift the bundle exit roller, stopping the
paper delivery motor (FPDM).
