MX-FN17  OPERATIONAL DESCRIPTIONS  6 – 12

When the operation mode command is received from the copier,
the finisher makes the finisher operation status command the JOB
and starts the transport operation.

1)

The paper transport motor (FPTM) is driven at the machine
paper discharge speed to receive paper discharged from the
machine. 
When the paper length is 216mm or less, the second and later
sheets in the same bundle are discharged from the machine at
the high speed. 
When the paper length exceeds 216mm, the sheets are dis-
charges at the same speed as the process speed.

1)

For the first sheet of a bundle, after turning on the paper pass
detector (FPPD1), 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. By turning on the paper pass detec-
tor (FPPD1), the paper alignment motor F (FPAM_F) and the
paper alignment motor R (FPAM_R) are driven to shift the
alignment plate to 15mm outside the paper and to put it under
the standby state. After transport of a certain amount, the
delivery roller lift motor (FDRLM) is driven to lift the bundle exit
roller to terminate the paper delivery motor (FPDM).

2)

For the second and later sheets, after transporting paper from
the paper pass detector (FPPD1) by a certain amount, the
paper alignment motor F (FPAM_F) and the paper alignment
motor R (FPAM_R) are driven to shift the alignment plate to
15mm outside the paper and to put it under the standby state.

3)

For the last sheet of a bundle, the paper pass detector
(FPPD1) is turned ON to drive the stapler shift motor (FSSM)
to shift the stapler to the binding position.

4)

After the paper rear edge passed the paper exit roller of the
main unit, the paper transport motor (FPTM) is accelerated to
480mm/sec.

5)

In the punch mode, punching is performed as described in "7.
Punching process."

6)

When the paper rear edge passes the paper pass detector
(FPPD1) and paper is transported by a certain amount, the
delivery roller lift motor (FDRLM) is driven to lower the bundle
roller and the paper delivery motor (FPDM) is driven in the
scrape direction at the paper exit speed of the main unit by a
certain amount to scrape paper to the process tray. In addition,
the paper alignment solenoid (FPAS) is turned ON to lower the
scrape belt.

7)

After completion of scrape, the delivery roller lift motor
(FDRLM) is driven to lift the bundle exit roller. The paper align-
ment motor F (FPAM_F) and the paper alignment motor R
(FPAM_R) are driven by a certain amount to align paper in the
process tray. If there are two or more sheets to be aligned, the
operation is repeated from "A-1)."

8)

After completion of alignment of a specified number of sheets,
the stapler motor (FSM) is started to staple at the specified
position.

1)

After completion of stapling, the paper alignment solenoid
(FPAS) is turned ON to lift the scrape belt. The paper align-
ment motor F (FPAM_F) and the paper alignment motor R
(FPAM_R) are driven to shift the alignment plate by 1mm from
paper. Then the delivery roller lift motor (FDRLM) is driven to
lower the bundle exit roller to press, and the paper delivery
motor (FPDM) is started at 450mm/sec to discharge paper
from the process tray.
