4) Bin shift motor rotation control
The bin shift motor that drives the lead cam is controlled depending
on the copy speed data sent from the copier.
The microcomputer on the sorter controller PWB controls the bin shift
motor as follows:
•
Paper exit: The bin roller is moved to the parallel section of the
lead cam and stopped there.
•
Transport: The bin is shifted by one.
The microcomputer on the sorter controller PWB controls the rpm of
the bin shift motor so that the bin is shifted by one during the
transport interval of copy paper.

(3) Guide bar control
1) Outline
The guide bar is in the bin unit. It oscillates as shown below.
The guide bar has the following functions:
The guide bar is driven by the guide bar oscillation motor (M3).
The guide bar home position sensor (PI3) detects that the guide bar
is in the home position.
