Section II Mechanism and
Operation
2.1 Outline of Operation
FA-F320 and host machine exchange signals through serial communication and carry
out the following 8 modes of operations.

2.2 Paper Transport Mechanism
2-2-1. Paper Transport Mechanism
When the punch registration sensor detects the paper, the transport motor
(M1) and belt motor (M3) are driven, driving gears and belts, which revolve
rollers.
(1) Face up paper Path (Discharged into upper bin)
The paper transport sensor detects the paper when transport motor (M1) is
driven and each roller is rotated. Then path select gate is switched to the
direction of A by gate solenoid, and the paper is discharged into upper bin by
exit roller.

and Operation
2-2-2. Paper Transport Mechanism (Interstage Stack)
(1) Face down (Discharged into lower bin)
The rollers are rotated by transport motor (M1). The paper passes through
the registration roller, path gate, paddle roller and is received by the stack.
After the paper is detected by the paper path sensor and jogged, the belt
motor is driven and the paper is discharged into the lower bin.

2.3 Punching Mechanism
A
B
2-3-1. Paper transport stop mechanism
Stop the paper momentarily at the punching position.
Process
The front end of the paper transported into FA-F320 passes through the paper
feed sensor.
• Punch registration clutch is turned ON.
When the normal close type CL1 is turned ON, the driving force to registration
roller is cut off, stopping the paper at registration roller.
• Papers are transported from the printer continuously. The lead edge of paper
is pressed against nip of the registration roller, which allows positioning of
each paper. The guide plate equipped with a spring moves downward to
compensate for the paper loop created during this process.
• The front end of the paper is punched by punch unit.
• CL1 is turned OFF, driving force is transmitted to the registration roller, and
the paper is transported.

Mechanism
and Operation
2-3-2. Punch Unit Drive Mechanism
Punch unit is composed of guide A, B, punch bar, cam, cam lifter, drive shaft,
and single punch clutch (CL2).
2-3-3. Punch Unit Drive
When transport motor is driven, the punch unit’s drive gear rotates punch
unit’s clutch gear.
But the driving force is not transmitted to drive shaft because the punch clutch
(CL2) is normally OFF and locked.
When CL2 is turned ON and the lock is released, the clutch gear’s rotation is
transmitted to the drive and the drive shaft is rotated.
(CL2 is turned ON momentarily, and is locked after one rotation, stopping the
movement of the shaft)
A rotation of the drive shaft causes a single vertical movement of punch bar
which is supported by the cam, punching the paper.

Pinion Gear
<Jogging Operation>
• Jogging bar moves the papers stacked in interstage stack to reference plate,
and jogs the papers toward STS. The papers are detected by sheet detecting
sensor when they are in the position where stapling is possible.
This procedure ensures stapling of the arranged papers.
Reference plate also ensures discharge into a fixed position.
<Shift Operation>
• Papers jogged to the direction of STS go through shift operation. Therefore,
single paper shifts by the shift bar are sorted when discharged.
(There is no shift operation for the stapled paper.)
<Jogging/Shift Mechanism>
• Jogging and shift operation is carried out by the jogging bar and shift bar
which are moved by pinion, which is driven by the A and B movement of
jogging motor (M2) gear.
• Holding spring pushes rack toward pinion to ensure proper engagement of
the rack and pinion. The jogging bar’s range of movement differs depending
on the size of paper (A4, LTR only).
Shift Bar (Rack A)

2-7
Mechanism
and Operation
<Detecting of Home Position>
• The jogging bar’s home position is decided by the light blocking plate integrated
into pinion and home position sensor.
• The jogging bar’s home position is the point where the sensor’s light starts to
be blocked by the blocking plate.
• The jogging bar and shift bar’s range of movement, which differs depending
on paper size, is calculated based on this position.

2-6-1. Control of Lower Bin Up/Down Movement
1 • The lower bin is elevated by the elevating motor (M4) to the point where
elevation ceiling or paper upper surface detecting sensor is activated.
• If paper is not in the bin, the elevation is stopped when elevation ceiling sensor
is activated.
• If paper is in the bin, elevation is stopped when the paper upper surface
detecting sensor is activated.
• When the elevation ceiling sensor is activated, A signal to indicate that the
bin is empty is transmitted to the host.
2 When the paper full sensor is activated after papers are discharged, the lower
bin moves until paper full sensor is deactivated.
3 When the lower bin is loaded fully and both elevation bottom sensor and
paper full detecting sensor are activated, the printer stops discharging papers.
4 When papers are removed from the lower bin and the paper upper surface
detecting sensor is deactivated, the lower bin is elevated.

Preventive
Maintenance
Section III Preventive
Maintenance
3.1 General
1. A Preventive maintenance inspection should be performed on the finisher at a
regular basis. If the preventive maintenance inspection is correctly performed, the
finisher can be maintained for a long period of time, machine down time and the
number of service calls can be minimized.
2. Refer to the attached chart for the schedule of replacements.
3. A high voltage hazard remains even when the machine is not operating.
Always disconnect the copier system from its power source (wall outlet) before
servicing or disassembly.
3.2 Recommended tools
1. The following items are necessary to perform an effective, time efficient P.M.
a) Vacuum cleaner
b) Blower brush
c) Isopropyl alcohol
d) Cleaning cotton
e) Lint free wiper (Kim wipes)
f) Cotton swabs
3.3 Cleaning recommendations
1. Refer to the appropriate PM cycle on the maintenance chart, where the cleaning
cycles is broken down by finisher.
Note: Use of IPA is strongly suggested, and only to be used when dry cleaning is
ineffective. Excessive use of IPA can decrease the operating life of rubber
components.
2. IPA should be used to clean the transport roller (only when required).
