6 OPERATION OF EACH MECHANISM
6-1. Paper Transport Mechanism
(1) Paper Transport Path
A sheet of paper fed out of the copier by the Paper Exit Roller/Rolls of the copier is fed
through, and out of, this unit by the unit’s Paper Exit Roller onto the unit’s Exit Tray.
Since this unit is mounted directly on top of the copier, Section over the copier Exit Tray, it
serves as an upper exit tray. The tray into which paper is fed out is selected depending on
the copying mode.
Exit Path Switching Plate
(2) Paper Exit Roller Drive
The Paper Exit Roller is driven by Transport Motor.

(3) Control of Transport Motor
A two-phase stepping motor is used as Transport Motor. The motor is tur ned as the pulse
signals output from PJ8A-1 to 4 are applied to it. The direction of the motor rotation is
switched by changing the output sequence of these pulse signals.

Transport Motor is energized when the paper fed through the copier during a copy cycle
activates the Paper Exit Sensor of the copier if the Upper Exit Tray is selected as the exit
port.
It is deenergized if the Paper Exit Sensor of the copier is not activated even after the lapse
of 1 sec. after Upper Exit Sensor has been deactivated.

6-2. Full-of-Paper Detecting Mechanism
(1) Job Tray
•
Paper is fed into the Upper Exit Tray or Lower Exit Tray depending on the copy mode.
The paper being fed into the tray operates the actuator, which unblocks and blocks the
Upper or Lower Full Detecting Sensor to allow the system to detect a full-of-paper condi-
tion.
(Upper Exit Tray)
A full-of-paper condition is detected when the Upper Full Detecting Sensor remains
unblocked for a continuous, given period time.
Upper Full Detecting Sensor PC2

(Lower Exit Tray)
A full-of-paper condition is detected when the Lower Full Detecting Sensor remains
unblocked for a continuous, given period time.

(2) Shift Tray
In the Shift Tray, a photointerruptor (PWB-B2, -C2) is used. When light from the PWB-C2
LED is blocked by a sheet of paper being fed out onto the tray, a full-of-paper condition is
detected.

6-3. Exit Path Switching Mechanism
The paper path is selected by energizing or deenergizing Path Switching Solenoid SL1,
which results in the Exit Path Switching Plate being swung down or up.
(1) Job Tray
The paper exit tray (Upper or Lower Exit Tray) is selected according to the setting made on
the copier.
When the Lower Exit Tray is selected, the Path Switching Solenoid is deenergized a given
period of time after the Paper Exit Sensor of the copier has been blocked, thereby feeding
the paper into the Lower Exit Tray.
In the 2-sided copy mode, the paper fed into this unit is reversed (switchback) and fed back
towards the Duplex Unit. (The Path Switching Solenoid is deenergized if the Paper Exit
Sensor of the copier is not blocked within a given period of time after the switchback operation has been started.)
(2) Shift Tray
In the 2-sided copy mode, if the length of the paper being fed into this unit exceeds 150
mm, the Path Switching Solenoid is energized after a given period of time after the Paper
Exit Sensor of the copier has been blocked to reverse the paper under the Exit Tray and
feed it back into the Duplex Unit.
If the length of the paper being fed into the unit is 150 mm or less, the Path Switching Solenoid is deenergized after a given period of time after the Paper Exit Sensor of the copier
has been blocked to transport the paper into the Exit Tray.

6-4. Initial Operation
The Transport Motor is energized at the same time when predrive of the copier is started
(Job Tray/Shift Tray).
The unit carries out the Shift T ray home position detection sequence when the Power
Switch of the copier is turned ON or when the Paper Misf eed Remo val Door is opened and
closed after a paper misfeed has been cleared (Shift Tray only).
(1) Shift Tray Home Position Detection
The unit determines that the Shift Tray is at its home position when the Shift Home Sensor
is blocked by the light blocking plate.
(If the Shift Tray is at its home position)
The Shift Motor is energized (forward or backward rotation) so that the Shift Home Sensor
is unblocked, then blocked again.
(If the Shift Tray is out of its home position)
The Shift Motor is energized until the Shift Home Sensor is blocked.

6-5. Paper Misfeed Removal Door Set Detection
The Paper Misfeed Removal Door is detected at its closed position by the Paper Misfeed
Removal Door Set Sensor. The unit determines that the door is left open if the sensor
remains unblocked for a given period of time and that it is closed if the sensor remains
blocked for a given period of time.
If the sensor is unblocked, a closure failure warning is given on the copier control panel and
the copier inhibits the initiation of a new copy cycle.

DIS/REASSEMBLY,
ADJUSTMENT
Precautions for Disassembly, Reassembly, and Adjustment
•
Before attempting to disassemble the unit, alwa ys make sure that no power is being sup-
plied from the copier (by unplugging the power connector from the copier).
•
While power is being supplied to the unit, do not attempt to remove/install the print jacks
from/to the PWBs or unplug/plug in the connectors.
•
If the unit is run with its covers removed, use care not to allow your clothing to be caught
in revolving parts.
•
The basic rule is do not run the unit with any of its parts removed.
•
A toothed washer is used with the screw that secures the ground wire to ensure positive
conduction. Do not forget to include this washer at reassembly.
•
To reassemble the unit, reverse the order of disassembly unless otherwise specified.
•
Do not attempt to remove or loosen the screws to which red paint has been applied.
