how to solve canon ir 5065 cassette 3 and 4 problem



When the cassette is pushed into the machine, the cassette open/closed sensor goes on and, at the same time, the pickup roller starts to move down. At this time, the light-blocking plate leaves the lifter sensor, causing the cassette lifter motor to go on and the lifter to move up. When the lifter moves up and the lifter sensor detects the surface of paper, its ascent stops.
When the open button of the cassette is pressed, the drive gear of the lifter becomes disengaged, letting the lifter to move down under its own weight.
