Paper Presence Detection
The presence/absence of paper in the deck is detected with the paper presence sensor.
When the paper is absent, the paper presence sensor flag passes through the paper
presence sensor, turning the paper presence sensor OFF.

In the case that the paper surface sensor 2 is ON and that the paper presence sensor is OFF,
it is judged that the paper is absent.
When there is no paper, the lifter moves down to the supply position (where the storage
supply position sensor is turned OFF→ON→OFF).

The presence/absence of paper is judged at the following timings:
• Immediately after the paper surface is positioned by moving up the lifter once the power is
turned ON or the deck is closed.
• During pickup operation
Paper's presence is detected as "indefinite" when the deck is open.
