2.2.1 Main Unit Paper Feed Mechanism

2.2.1.1 Until the Paper is Set at the Position Before the Secondary
Transfer (Registration)
By turning on the Pickup Clutch for a certain period of time, the Pickup Roller rotates
by 360 degrees to feed one sheet of paper to the Feed Roller 1. The paper supplied to
the Feed Roller 1 is transported to the Feed Roller 2 and then hit against the Gate
Roller for skew correction. Then the Gate Clutch and Feed Clutch start to rotate by
being turned on for a given time to transport the paper to the secondary transfer section.
PAPER CASSETTE
Lift Plate Lock Mechanism
When the Lift Plate is pressed down, it is locked by the lock lever on the right side
of the cassette. The lock is released when the cassette is set into the main unit and
the paper in it is lifted up to the feeding (pickup) position by the Lift Plate which
lifts up by the spring force.
Paper Cassette Sensor
A mechanical contact switch that detects whether the Paper Cassette is installed or
not. The printer detects the Paper Cassette while the switch is pressed down by the
actuator of the cassette.
Paper Sensor
A photo-interrupter sensor that detects whether the paper is loaded or not. The
actuator works depending on whether the paper is loaded, and the shield board on
the actuator switches ON/OFF the sensor.
