AR-F13 OPERATIONAL DESCRIPTION 4-16

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

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

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 (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.

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
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 .

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

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).

The inlet sensor does not detect paper approximately 1.5 sec after the host machine generates the delivery signal.

The paper does not leave the inlet sensor approximately 2 sec after the inlet sensor has detected its leading edge.

In bind mode, the folding position sensor does not detect paper 1200 msec after the intermediate processing tray starts to send paper to the stapling

position.

In bind mode, paper does not leave the holding position sensor approximately 10.5 sec after the staple/fold motor is driven.

Paper is detected inside the finisher at power-on or when the door is closed.

The finisher is disconnected from its host machine or the front door, or the upper cover is opened while the system is in operation (paper on the move).

The staple home position sensor (STHPS) does not go OFF 600 msec after the stapler is driven. Or, it does not return to its home position (where the

sensor goes ON).

AR-F13 OPERATIONAL DESCRIPTION 4-18

When the host machine is turned on, it supplies the finisher controller PCB with two channels of 24 VDC; one is for the motors and clutches, and the

other is turned into 5 VDC by the regulator IC (IC1) of the finisher controller PCB for use by the sensors and ICs on PCBs.
If a punch unit (option) is installed, power is also supplied to the punch controller PCB.

Some of 24 VDC used to drive motors is cut off when the joint switch (JS), front door switch (FDSW), or stapler safety switch (SSS) is open.

A circuit breaker (CB1) is monitored to protect the 24 VDC system sued to drive the motors against overcurrent. The 24-V system used to drive the

feed motor (FFM), paddle motor (FPM), and delivery motor (FAM) is equipped with a fuse which melts in the presence of overcurrent.

When the host machine is turned on, the puncher unit is supplied by the finisher controller PCB with 24-V and 5-V power.

The 24-V power is used to drive the motors, while the 5-V power is used by sensors and the ICs on the punch controller PCB.

The 24-V power to the motors will be cut off when the joint switch (MS2) or the front door switch (MS1) of the finisher unit is open.
