Paper Feed Unit
(8) Elevator Lower Switch
Description
The feed tray stops when the screw that is attached to
the chain that raises and lowers the feed tray turns the
micro switch on.
The feed tray is determined to be at its lower limit when
the micro switch is on, and the feed tray will not go any
lower.
If the elevator lower switch is on because there is too
much paper loaded on the feed tray, and the paper level
sensor is on (light is not transmitted), then a J5: OVER
CAPACITY error occurs.
