diagram (on waterproof paper).

Symbol Index No. Description Note
Motors

M1 13 Entrance Drives the feed roller and the entry roller.
M2 14 Exit Drives the inverter roller and the exit rollers.
M3 18 Tray Shift Moves the 1st bin from side to side.
M4 16 Tray Lift Moves the 1st bin up or down.

Solenoids

SOL1 4 2nd Bin Gate Opens and closes the 2nd bin gate to direct

the copies into either the 2nd bin or 1st bin.

SOL2 5 3rd Bin Gate Opens and closes the 3rd bin gate to direct

the copies into either the 3rd bin or the other
bins.

SOL3 6 Junction Gate Opens and closes the junction gate to direct

copies into either the inverter area or other
exits.

SOL4 7 Pinch Roller In face down mode, contacts the return

pinch roller with the copy to deliver the copy
to bin 1, 2, or 3.

3.1.1 FACE-UP MODE

[D]

[A]

[B]

A849D001.WMF

A849D002.WMF

Copies exiting the copier pass through the entrance guide plate [A]. The entry roller
will send copies either to the inverter bin or to each bin, depending on the selected
mode.

When the sorter receives the feed-out s ignal from the main machine, th e entrance
motor and exit motor energize to rotate all the rollers in the sorter. During copying,
all rollers transport the paper at a speed that depends on the copier. When the
leading edge of the copy passes the entry sensor [B], the speed of the rollers
changes to 550 mm/s.

- 1st, 2nd and 3rd bins -

When the junction gate [C] is closed as sh own above, the copies pass through the
upper part of the junction gate. For 1st bin output mode, the copy goes straight up
from the junction gate directly to the bin. For the 2nd and 3rd bins, the copies from
the junction gate are delivered to these bins, as directed by the 2nd bin gate [D]
and 3rd bin gate [E].

A849D004.WMF

When the junction gate [A ] is opened, the copy goes to the inverter bin [B] through
the lower part of the junction. When the trailing edge of the copy passes through
the inverter sensor [C], the return pinch rollers [D] lower to contact the copy, then
the copy is fed back in by the rollers. The copy is fed out to any output bin and it
arrives face down.
