Figure 1-50 Paper deck lift-up operation Cassette 1 Cassette 2 Cassette 3 PD cassette 3 media stack surface sensor SR92 Lifter Lifting plate The operational sequence of the lift-up is as follows: 1. The PD cassette 3 lifter motor rotates to raise the lifter. 2. The PD cassette 3 lifter motor stops when the PD cassette 3 media stack surface sensor detects the paper surface. 3. The PD cassette 3 lifter motor rotates again when the PD cassette 3 media stack surface sensor detects that the stack surface lowers during a print operation. 64 Chapter 1 Theory of operation ENWW PD cassette 3 lifter motor M92
