5. Power-On Jam (87H)
The No. 1 paper sensor (PI1A) or the delivery sensor (PI11) on the paper sensor PCB detects
paper at time of power-on.
6. Door Open Jam (88H/89H)
The front door sensor (PI2), outlet cover sensor (PI3), or inlet cover sensor (PI9) finds that the
respective cover is open during operation.
7. Stitcher Staple Jam
When the stitcher motor (M7S/M6S) is rotating clockwise, the stitcher home position sensor
(PS4S/PS2S) does not turn on within 0.5 sec after it has turned off but, in addition, the sensor turns
on within 0.5 sec after the motor has been rotated counterclockwise.
Reference:
When all doors are closed after the user has removed the jam, the saddle stitcher unit checks whether
the vertical path paper sensor (PI17S) has detected paper or not. If the sensor has detected paper, the
unit will identify the condition as being faulty jam removal and send the jam signal to the copier once
again.
