Section II Operation
2.1 Mechanism
Motors
(1) Transport motor - The transport motor provides drive for the upper paper exit roller
and the reverse roller 1.
(2) Reverse motor - The reverse motor provides drive for the lower paper exit roller
and the reverse roller 2.
(3) Shift motor - The shift motor provides drive to shift the upper tray frontward and
backward.
2.2 Theory of operation
Normal paper exit (Face up exit)
When the start button is pressed, the transport motor is turned on, rotating the
reverse roller 1 and the upper paper exit roller. The copy exits the copier and is fed
into the inverting shift tray. The copy passes over the switching guide plate through
the upper paper exit sensor unit, and is transported to the upper tray by the upper
paper exit roller. The paper exit roller is slowed prior to the exit of the copy in order
to stack the copies neatly. When the copy cycle is completed, the transport motor is
turned off.
Operation
Upper inverse paper exit (Face down exit with printer function)
When the start button is pressed, the transport motor is turned on, rotating the
reverse roller 1 and the upper paper exit roller. The copy exits the copier and is fed
into the inverting shift tray. The reverse solenoid in the inverting shift tray is turned
on in order to open the switching guide (Section A Fig. 2-01). This process redirects
the copy to the reverse roller 1. The reverse roller 1 transports the copy to the
reverse roller 2, passing the copy through the reverse transport sensor unit. The
reverse roller 2, which is driven by the reverse motor, rotates in the normal direction
when the lead edge of the copy passes through the reverse transport sensor, and
rotates in the reverse direction after a lapse of predetermined time since the trail
edge of the copy passed through the reverse transport sensor in order to transport
the copy to the upper paper exit roller. This reverse rotation starts when the trail
edge of the copy is still within the limits of the switching guide 2 (Section B Fig.
2-01). The reverse motor is turned off after a lapse of predetermined time since the
2-1
reverse paper exit sensor detected the trail edge of the copy. The copy is then
transported to the upper tray via the upper paper exit roller unit. The upper paper
exit roller is slowed prior to the exit of the copy in order to stack the copies neatly.
When the copy cycle is completed, the transport motor is turned off.
Lower inverse paper exit (Face down exit with printer function)
When the start button is pressed, the transport motor is turned on, rotating the
reverse roller 1 and upper paper exit roller. The copy exits the copier and is fed into
the inverting shift tray. The reverse solenoid in the inverting shift tray is turned on in
order to open the switching guide (Section A Fig. 2-01). This process redirects the
copy to the reverse roller 1. The reverse roller 1 transports the copy to the reverse
roller 2, passing the copy through the reverse transport sensor unit. The reverse
roller 2, which is driven by the reverse motor, rotates in the normal direction when
the lead edge of the copy passes through the reverse transport sensor, and rotates
in the reverse direction after a lapse of predetermined time since the trail edge of
the copy passed through the reverse transport sensor in order to transport the copy
to the lower paper exit roller. This reverse rotation starts after the trail edge of the
copy passed through the switching guide 2 (Section B Fig. 2-01). The switching
guide 2 is mounted to be able to rotate freely. The copy passes, pushing the switching
guide 2 up, and is transported to the reverse roller 2. The switching guide 2 is
released from being pushed up by the copy after the trail edge of the copy passed
through, so that the copy is led to the lower paper exit roller when it exits in reverse,
or is transported to the lower tray via the lower paper exit roller. (In the lower side,
the roller is not slowed down.) The reverse motor is turned off after a lapse of
predetermined time since the copy passed through the lower paper exit sensor.
When the copy cycle is completed, the transport motor is turned off.
Shift operation (Upper tray only)
The shift operation is performed after the copy exited the inverting shift tray. When
the upper paper exit sensor in the inverting shift tray detects the copy passing
through, the shift motor shifts the tray slide plate. The shift motor shifts the tray
about 30 mm with a crank. It will remain there until the last copy of the current copy
set exits. The shift motor is then energized again to return the shift tray to the home
position, and is turned off when the shift home position sensor detects the return.
2-2
Decelerated paper exit operation
The paper exit roller is slowed after a lapse of predetermined time since the paper
exit sensor of the copier or the reverse paper exit sensor detected the trail edge of
the copy. Slowing of the paper exit roller is accomplished through use of the paper
exit deceleration clutch and speed reduction gears. The clutch is turned off after a
lapse of predetermined time since the upper paper exit sensor detected the trail
edge of the copy, returning the paper exit roller to normal speed.
