(3)Horizontal Registration Operation
The horizontal registration drive for the punch slide unit is provided by
the horizontal registration motor (FPSM). The home position of the
punch slide unit is detected by the horizontal registration home position
punch slide unit is detected by the horizontal registration home position
sensor (PSHPS). The punch slide unit detects the trailing edge of sheets
using the trailing edge sensor (LED5, PT5) and the horizontal
registration sensors (LED1 through 4, SREG1 through 4), and causes a
registration sensors (LED1 through 4, SREG1 through 4), and causes a
move to a specific position matching the trailing edge of each sheet
(in relation to the size of the sheet).
The horizontal registration operation takes place as follows:
The horizontal registration operation takes place as follows:
1) When the leading edge of a sheet from the host machine is detected
by the trailing edge sensor (LED5, PT5), the horizontal registration
motor (FPSM) starts to move the punch slide unit toward the front.

2) When the horizontal registration sensor (LED1 through 4, PT1
through) suited to the paper size signal from the host machine
detects the rear edge of the sheet, the horizontal registration motor
(FPSM) causes a farther move to a specific position, and stops the
punch slide unit.
punch slide unit.

3) When the trailing edge sensor (LED5, PT5) detects the trailing edge
of the sheet, the drive of the feed motor (FFM) is stopped, thereby
stopping the sheet. Then, the punch motor (FPNM) is driven to
stopping the sheet. Then, the punch motor (FPNM) is driven to
punch holes in the sheet.

4) When the punching operation ends, the feed motor (FFM) of the
fisher unit is driven and, at the same time, the horizontal 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 .

7. Detecting Jams
A.Outline
The microprocessor (CPU) on the finisher controller PCB is programmed
to check for jams in the finisher/saddle/puncher (option) at such times as
set in advance. It identifies a jam in reference to the presence/absence of
paper at a specific sensor. If a jam is found, the finisher controller PCB
paper at a specific sensor. If a jam is found, the finisher controller PCB
communicates the nature of the jam to the host machine in the form of a
code(which may be checked in service mode of the host machine).
