The upper limit sensor [A] controls the tray lift motor [B]. The actuator [C] for
the sensors is on the feed roller shaft [D]. The tray lift motor drives the bottom
plate [E] which is attached to the timing belts [F] through the gear [G] and the
drive pulleys [H].
The paper feed rollers [I] are always lowered by the weights [J]. When the
LCT cover is closed, the tray lift motor will start rotating and the bottom plate
start lifting.
When the top sheet of the paper stack raises the paper feed roller, the upper
limit sensor is activated and the tray lift motor will stop.
During copying, when the level of the paper stack has fallen past a certain
point (when the actuator [C] exits the upper limit sensor), the tray lift motor
will turn on to maintain the correct level for paper feed.
