Copier paper exit signal
Transport motor (M2)
Paper exit sensor (PI1)
Jam signal (SJAM)
300msec transport time (Varies depending on the model)
2) Transport remaining jam
The paper does not pass over the paper exit sensor within the
transport time of 2 sheets of copy paper after the paper exit sensor
(PS1) detects the paper.
Transport motor (M2)
Paper exit sensor (PI1)
Jam signal (SJAM)
a: Copy paper length x 2 (mm) + copier's paper exit speed (mm/sec)
3) Power ON jam (Jam paper remaining detection)
When the power switch of the copier is turned on, if the paper exit
sensor is ON, the SJAM signal is generated.
4) Door open jam
When the sorter is separated from the copier during operation, the
SJAM signal is generated.
After removing the above jam error, press the copy start key, and
the remaining quantity of copies are automatically made by the
jam correction function. ON the other hand, when a jam occurs in
the copier, all the copy papers transporting in the sorter are dis-
charged to the specified bin and the sorter is stopped.

(2) Bin unit
1) Bin unit composition
The bin unit is composed as shown below.
The both sides of each bin are provided with the roller from the
outside of the bin frame. The dummy rollers on the upper and the
lower sides are integrated with the bin unit and fixed to the both ends
of the bin frame.
The lower dummy roller is of eccentric shape to adjust the bin roller
height.
2) Lead cam function
The lead cam is attached to be engaged with the bin unit roller. It is
driven by the bin shift motor (M1) which can rotate forward and
reverse.
