6.9.10 PAPER TABLE MECHANISM
Table Up and Down Mechanism
An independent dc motor, the paper table motor [A], drives the paper table. When
the motor turns, the pinions [B] turn on the racks [C], lifting up or lowering the paper
table.
There are two paper height sensors.
• Sensor 1 [E] is actuated when the top of the stack pushes the pick-up roller [D] to
a certain height.
• Sensor 2 [I] is actuated when the top of the stack pushes a feeler [H].
When the paper table moves up, the top of the paper stack contacts the pick-up
roller [D] or feeler [H], lifting it up. Then, when paper height sensor 1 [E] or 2 [I] is
actuated, the paper table stops.
During a printing run, sheets are fed from the stack, and the paper pick-up roller
and feeler both drop. When the paper height sensor 1 or 2 is de-actuated, the
paper table motor starts turning and lifts the paper table until the sensor is actuated
