Paper Presence/Absence Detection Control
The presence/absence of paper inside each deck is checked by the deck paper sensor (S103,
S203, S303).
When the paper runs out and the paper detecting lever of the pickup roller assembly moves
past the deck paper presence/absence sensor (S103, S203, S303), the host machine
indicates the absence of paper on its control panel.
