Movement Of The Cassette Lifter - Canon NP6330 Service Manual

CHAPTER 5 PICK-UP/FEEDING SYSTEM
B. Movement of the Cassette Lifter
When the cassette is pushed inside the copier, the pick-up roller moves down, and
the light-blocking plate leaves the lifter position sensor (PS3, PS5), thereby turning on
the lifter motor (M9, M10) to move up the lifter. The lifter motor stops where the lifter
position sensor (PS3, PS5) can detect the top surface of the stack of copy paper on the
lifter.
When the cassette runs out of copy paper and the paper detection roll mounted to
the pick-up roller shaft falls and, as a result, the paper detecting lever leaves the paper
sensor (PS2, PS4), the "Add Paper indicator" will be lighted on the control panel.
