This operation is divided into two operations: the initial lift-up operation and the lift-up operation during printing.
1. Initial lift-up operation
When the power is turned ON or a cassette is inserted, the Lifter Motor (M103) is driven to lift up the Lifting Plate to the
position for detection if the Paper Surface Detection Sensors 1 and 2 (PS107 and PS907) do not detect the paper surface.
2. Lift-up operation during printing
This operation is performed if the paper surface is lowered a certain amount by the pickup operation.
If the Paper Surface Detection Sensors 1 and 2 (PS107 and PS907) detect that there is no paper during printing, the Lifter
Motor (M103) is driven to lift up the Lifting Plate to the pickup position.

■ Cassette Paper Size Detection/Cassette Detection
The Cassette Size Switch (SW102/1600) detects the size of paper set in the cassette.
The switch consists of 3 microswitches, and the width is detected in accordance with the combination of ON/OFF.
When the cassette presence/paper size is changed, the DC Controller notifies the Main Controller of the status change.
If the paper size detected by the switches differs from the specified size, paper size mismatch is notified.
