Identifying The Presence/Absence Of Paper - Canon NP6330 Service Manual

CHAPTER 8 PAPER DECK PEDESTAL

2. Identifying the Presence/Absence of Paper

The presence and absence of copy paper inside the paper deck is identified by the
deck paper sensor (PS4).
When the paper deck runs out of paper, the paper detecting spacer attached to the
pick-up roller shaft drops.
As a result, the paper detecting lever leaves the deck paper sensor (PS4), causing
the pedestal controller PCB to identify the absence of paper.
