562 TSM Océ 3121 Functional description of the sorter
■
Advance rotation of the cam
In sort mode, the lead cam rotates in advance.
To ensure that the bins are in position before the copy arrives, the lead cam is
first rotated the equivalent distance to the width of the flat section. The move-
ment commences when PI3 detects the leading edge of the sheet. The bin will
not move.
When the sheet leaves PI3, the rotation of the cam will continue for the length
of the slope until the flat section is reached. The bin will be moved.

Slope section
1) An output arrives from the copier, and its leading edge
reaches the delivery roller.
(The bin unit delivery sensor turns on.)
2) The lead cam rotates over the distance of its level sec-
tion and stops (advance rotation).
(The bin position remains the same.)
3) The trailing edge of the output moves past the delivery
roller.
(The delivery sensor turns off.)
4) The lead cam rotates for the distance of its slope sec-
tion. (The bin shifts.)
1) An output exits the copier and its leading
edge reaches the delivery roller. (the bin
unit delivery sensor switches on)
2) The lead cam rotates over the distance of
its level section and stops (advance rota-
tion). The bin position remains the same.
3) The trailing edge of the output moves
past the delivery roller. (the delivery
roller switches off).
4) The lead cam rotates for the distance
of its slope section. (the bin shifts).
