Paper Presence/Absence Detection Control; Paper Surface Detection Control - Canon POD Deck Lite-C1 Service Manual

Paper Presence/Absence Detection Control

The presence/absence of paper inside the compartment is checked by the deck paper sensor (SR15) of the pickup assembly.
When the paper runs out and the paper detecting lever of the pickup assembly passed the deck paper sensor (SR15) as a result,
the host machine indicates the absence of paper on its control panel.

Paper Surface Detection Control

The paper level sensor (SR3) mounted at the pickup assembly is used to detect the paper surface. When the detection flag of
the pickup roller holder is pushed up by the top surface of paper with the upward movement of the lifter, the paper level sensor
(SR3) detects it and the lifter stops to keep the top surface of paper at the pickup position.
