• 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.
Paper deck motor 2 (PDM2) drives the right lift belt assembly that winches the belt up and hence raises the lift until it is
stopped by deck level switch 2 (DLSW2).
When paper is loaded on the lift and the deck is closed, the lift is raised until deck level switch 2 (DLSW2) turns on.
When desk level switch 2 (DLSW2) is turned off as the paper on the lift is used, paper deck motor 2 (PDM2) starts to raise
the lift until the switch turns on.

Figure 2-1-6 Raising and lowering the lift
When the deck is opened for removing a jammed paper or other purposes, the winch shaft is released from its holder on
paper deck motor 2 (PDM2), allowing the lift to descend under its own weight. The air damper buffers the impact of the
descending lift.
