Paper Feed Unit
(6) Elevator Motor
Description
The elevator motor raises and lowers the feed tray.
When there is no paper on the feed tray, the feed tray
lowers until it triggers the elevator lower SW.
However, if paper is loaded on the feed tray while it is
lowering (paper sensor is not transmitting light), the
elevator motor stops and the feed tray stops lowering.
The feed tray rises until the paper level sensor is on
(light is not transmitted) while paper is being fed.
During a paper feed retry operation, the feed tray
continues to lower until the paper level sensor goes off
(light is transmitted) for a period. Then the feed tray
rises until the paper level sensor goes on (light is not
transmitted).
If paper does not reach the elevator upper switch,
elevator lower switch, or paper level sensor after a set
time (*) after the elevator operation, an E8: ELEVATOR
ERROR occurs.
* 10 seconds when rising at start, 3.5 seconds during
paper feed operations, 9 seconds when lowering at
stop
