PAPER LIFTING MOTION CONTROL
 When Tray is slid in
 When the Lift-Up Sensor (PC7-PC) of the Optional Cassette is
unblocked (OFF) with the Optional Cassette being closed, the Lift-Up
Motor (M3-PC) of the Optional Cassette will rotate to start lifting up
the Paper Lifting Plate.
 When the Lift-Up Sensor (PC7-PC) of the Optional Cassette is blocked
(ON) after the Paper Lifting Plate starts moving up, the Lift-Up Motor
(M3-PC) of the Optional Cassette will stop to finish lifting the Paper
Lifting Plate.

 Timing for Motion
 During a print cycle
 When the amount of paper decreases as the Unit keeps printing, the
Feed Roller will gradually come down to unblock the Lift-Up Sensor
(PC7-PC) of the Optional Cassette. The Lift-Up Motor (M3-PC) will
rotate again to lift up the Paper Lifting Plate.
 When the Lift-Up Sensor (PC7-PC) is blocked (ON), the Lift-Up
Motor (M3-PC) of the Optional Cassette will stop to finish lifting the
Paper Lifting Plate.
 The sequence of these operations is repeated to keep constant the
pressure between the Paper Take-up Roller and paper stack (paper
take-up pressure) regardless of the amount of paper still available for
use.
