(3) Horizontal Registration Operation
The horizontal registration drive for the punch slide unit is provided
by the punch horizontal registration motor (FPSM). The home posi-
tion of the punch slide unit is detected by the punch horizontal reg-
istration home position sensor (FPSHPD). The punch slide unit
detects the trailing edge of sheets using the trailing edge sensor
(FPTD) and the horizontal registration sensors (FPSD1 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:
1)
When the leading edge of a sheet from the host machine is
detected by the trailing edge sensor (FPTD), the punch hori-
zontal registration motor (FPSM) starts to move the punch
slide unit toward the front.

2)
When the horizontal registration sensor (FPSD1 through 4)
suited to the paper size signal from the host machine detects
the rear edge of the sheet, the punch horizontal registration
motor (FPSM) causes a farther move to a specific position,
and stops the punch slide unit.

3)
When the trailing edge sensor (FPTD) 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 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 punch hori-
zontal 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.

G. Detecting Jams
(1) Outline
The microprocessor (CPU) on the finisher controller PCB is pro-
grammed 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 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).
