Detecting The Level Of Paper In The Deck - Canon iR5000 Service Manual

CHAPTER 8 PAPER DECK

1.3.3 Detecting the Level of Paper in the Deck

The machine uses the deck paper supply position sensor (PS107), deck paper level sensor
(PS108), and deck paper sensor (PS102) to check the level of paper inside its compartment;
it can also indicate the detected level in the control panel of its host machine.
The following shows how the level is determined with reference to the combination of the
states of sensors and how each level is indicated:
Level of paper
100% to about 50%
about 50% to about 10%
less than 10%
No paper
1: light-blocking plate over
the sensor.
0: light-blocking plate not
over the sensor.
