Raising And Lowering The Lift - Kyocera Mita KM-4530 Service Manual

(2-3) Raising and lowering the lift

The mechanism of paper lifting with the deck lift is same for drawers 3 and 4, so only drawer 3 is explained here.
The deck lift is suspended with wire at four points, and the deck right lift motor (DLM-R) drives the lift by winding up the
wire. The stop control of the deck lift at the upper limit is performed with deck lift limit switch 1 (DLILSW1).
When paper is loaded on the deck lift and the drawer is set in the copier, the deck right lift motor (DLM-R) turns on to
start winding up the wire. The deck lift rises until the leading edge of the paper turns deck lift limit switch 1 (DLILSW1) on
and then stops. When deck lift limit switch 1 (DLILSW1) is turned off as the paper on the lift is used for copying, the deck
lift is raised until the deck right lift motor (DLM-R) turns on again and the leading edge of the paper turns deck lift limit
switch 1 (DLILSW1) on.
When the drawer is pulled out from the copier for loading paper or other purposes, the lift drive shaft is released from the
coupler of the deck right lift motor (DLM-R), allowing the lift to descend under its own weight. The damper mounted via a
gear to the lift drive shaft buffers the impact of the descending lift.
