Deck Paper Level Detection

The deck uses the deck paper supply position sensor (PS107), deck paper level sensor (PS108),
and deck paper absent sensor (PS102) to find out and communicate to the copier an approximate
level of paper inside its compartment so that the level may be indicated in the copier's control panel.
Table 10-101 shows the possible combinations of sensor outputs and levels of paper.
