K. Detecting Jams
1. Outline
As man as nine paper sensors are used (Figure 7-142) to make sure that paper is moving
through the machine normally.
The presence/absence of paper is checked at such times as programmed in the microprocessor
(DC controller) on the image processor PCB; upon detection of a jam, the main motor is stopped
and a Jam message will be indicated on the control panel.
