A566D001.wmf
A566D002.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 signal from the main machine, the
entrance motor and exit motor energize to rotate the all rollers in the sorter.
During copying, all rollers transport the paper at a speed which 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 shown 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].

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.
