Paper lifting motion

• When the drawer is slid into the main unit and the Set Sensor is activated, the Lift-up
Motor starts rotating to raise the Paper Lifting Plate.
• The paper stack of the drawer pushes up the Pick-up Roller. When the upper limit posi-
tion is detected through the action of the actuator, it stops raising the paper lifting plate.
• As paper is consumed during the print cycle and the Pick-up Roller is lowered, the Lift-up
Motor is energized until the Lift-up Upper Limit Sensor is blocked again.
A. When the drawer is slid in
1. The paper lifting plate goes up and the top surface of the paper stack pushes up the
roller.
2. The lifting motion stops as soon as the sensor detects the upper limit position.
