Jam Detection; Overview - Canon GP160F Service Manual

CHAPTER 10 CASSETTE FEEDER
VI. JAM DETECTION
A.

Overview

The cassette feeder is equipped with a pick-up sensor (PS651), which monitors the
pick-up and feeding function. It is also equipped with a paper supply sensor, which
detects the presence or absence of paper.
According to a pre-programmed timing, the feeder controller PCB's CPU (IC601)
performs checks to determine whether there is paper or not in the sensor area, as well
as checks for jams. When the sensor judges there is a jam, the main unit's motor and
the feeder motor are immediately turned OFF, and a jam message is displayed on the
control panel.
Reference:
For more information regarding jam sensor timing after the main unit's registration
sensor, please refer to the main unit's service manual.
