Raising and lowering the lifts
The following is a description of the right cassette lift operating mechanism. The left cassette lift operates in the same
manner.
Lift motor 2 (LM2) drives the right lift belt assembly that winches the belt up and hence raises the lift until it is stopped by
level switch 2 (LSW2).
When paper is loaded on the lift and the deck is closed, the lift is raised until level switch 2 (LSW2) turns on.
When level switch 2 (LSW2) is turned off as the paper on the lift is used, lift motor 2 (LM2) starts to raise the lift until the
switch turns on.
When the cassette is opened for removing a jammed paper or other purposes, the winch shaft is released from its holder
on lift motor 2 (LM2), allowing the lift to descend under its own weight. The air damper buffers the impact of the descend-
ing lift.
