Feed and Lift: Tray 1
[B]
B070D097.WMF
When the tray lift motor turns on, the pick-up solenoid [A] actuates and lowers the
pick-up roller [B]. When the top of the stack reaches the correct height for paper
feed, it pushes up the pick-up roller and lowers the actuator [C]. This actuator de-
activates the tray lift sensor [D] when it leaves the sensor slot, and this stops the
tray lift motor.
After several paper feeds, the pick-up roller descends and the actuator rises and
enters the tray lift sensor and activates it. This switches on the tray lift motor again,
which raises the stack once again to the correct paper height.
When the tray is pulled out of the feed unit, the lift motor coupling gear [E]
disengages the pin [F] on the lift shaft [G], then the tray bottom plate [H] drops. The
damper provides resistance so the tray descends slowly.
There is also a paper end sensor for the 1st tray, which works in the same way as
the sensor in the 2nd and 3rd trays.
