Section II Operation

2.1 Mechanism

Motors

(1) Transport motor-The Transport motor provides drive for the paper exit and reverse

roller 1.

(2) Reverse motor-The Reverse motor provides drive for reverse roller 2 and for

forward and reverse operation of the transport section.

(3) Shift motor-The shift motor provides drive for the tray shifting mechanism. (Inverting

shift tray only)

2.2 Theory of operation

Normal paper exit

When the start button is pressed on the copier, the transport motor in the inverting
shift tray / inverting unit is turned on, rotating reverse roller 1 and the paper exit
rollers.
The copy exits the copier and is fed into the inverting shift tray / inverting unit.
The copy then passes over the copy switching guide, under the shift/reverse paper
exit sensor, to the paper exit rollers, and finally into the shift tray.
The exit rollers are slowed prior to the exiting of the copy in order to stack the
copies neatly in the tray. (Refer to the copy deceleration section for details.)
When the copier cycles down the transport motor, in the inverting shift tray / inverting
unit is turned off.

Operation

Inverse paper exit

When the start button is pressed on the copier, the transport motor in the inverting
shift tray / inverting unit is turned on, rotating reverse roller 1 and the paper exit
rollers. The copy exits the copier and is fed into the inverting shift tray / inverting
unit.
The inverting shift tray / inverting unit energizes the reverse solenoid to open the
switching guide. (Point A in diagram 2-01)
This process redirects the copy to the reverse roller 1. Reverse roller 1 transports
the copy past the shift/reverse transport sensor and to reverse roller 2.
Reverse roller 2 , (driven by the reverse motor) transports the lead edge of the copy
past the shift/reverse transport sensor until the trail edge of the copy is detected by
the shift/reverse transport sensor.

2-1

The reverse motor then changes direction and transports the copy towards the exit
rollers.
Copy direction (point B in diagram 2.1) is accomplished by utilizing the gap formed
by the guide plate and mylar on the transport guide.
The reverse motor is turned off pre-determined time after the shift/reverse sensor
detects the copy’s trail edge. (Formerly the lead edge of the copy before the reverse
operation.)
The copy is then fed to the paper exit rollers and finally into the shift tray.
The exit rollers are slowed prior to the exiting of the copy in order to stack the
copies neatly in the tray.
(Refer to the copy deceleration section for details). When the copier cycles down
the transport motor in the inverting shift tray / inverting unit is turned off.

Shift operation (Inverting shift tray only)

Movement of the shift tray to the offset position occurs after the last copy of a set
has exited the inverting shift tray. The shifting motor rotates the tray position occurs
after the last copy of a set has exited the inverting shift tray.
The shifting motor rotates the tray rotation plate eccentric cam for predetermined
time until the tray has shifted 30 mm. It will remain there until the last copy of the
current copy set has exited the inverting shift tray.
The shift motor is then energized again to return the shift tray to the home position
activating the shift home position sensor.

Copy deceleration

To allow the copies to be placed in the tray more uniformly, the exit rollers are
slowed down pre-determined time after the copier exit sensor detects the trail edge
of the copy. The slowing of the exit roller is accomplished through use of the speed
reduction gears of the paper deceleration clutch. The clutch is turned off pre­determined time after the shift/reverse exit sensor detects the trail edge of the copy,
returning the exit rollers to normal speed.
