Tray ascent operation

• When the drawer is slid into the main unit and the Set Sensor is activated, the Lift 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
Motor is energized until the Lift Sensor is blocked again.
A. Operation overview (when Tray is slid in)
