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.
PAGE 178
28 March 2006 PAPER FEED again. In this way, the top of the paper stack remains at the same position during printing. When the tray lowers, the lower limit position is detected by the lower limit sensor [F], which is beside the paper table motor. When paper runs out, the paper feed table lowers, until the paper table lower limit sensor (not shown) detects the lower limit position. Why do we have two height sensors? Note that the feeler [H] is at a different part of the stack from the pick-up roller [D].
PAGE 179
PAPER FEED March 2006 6.9.11 PAPER TABLE SIDE FENCE MECHANISM [B] [C] [A] C267D952.WMF The left and right side fences [A] move together due to a rack and pinion mechanism. There is a lock lever [B] to hold the side fences in position. NOTE: The lock lever may be useful if there is no dedicated operator and some of the operators cannot set the side fences properly, causing paper feed problems. Advise the operator to use the lock lever once the paper fences are properly adjusted.
