MX-FN11  OPERATIONAL DESCRIPTION  4 – 14

3) When the trailing edge sensor (LED5, PT5) detects the trailing

edge of the sheet, the drive of the punch feed motor (FSIFM) is
stopped, thereby stopping the sheet. Then, the punch motor
(FPNM) is driven to punch holes in the sheet.

4) When the punching operation ends, the punch feed motor

(FSIFM) of the finisher is driven and, at the same time, the hor-
izontal registration motor (FPSM) is rotated in reverse to return
the punch slide unit to its home position.

5) For each sheet that arrives in succession, the punch slide unit

is returned to its home position, and is caused to repeat steps
1 through 4.
