printer recovers from sleep mode and when the paper-feeder cassette is installed. The operational
sequence of the lift operation is as follows:
1. The paper-feeder driver rotates the paper-feeder lifter motor to lift the lifting plate.
2. The paper-feeder driver stops the paper-feeder lifter motor when the paper-feeder media-stack
surface sensor 2 detects the stack surface.
3. The paper-feeder driver rotates the lifter motor again when paper-feeder media stack surface 1
detects that the media surface is lowered during a print operation.
Figure 5-48 Paper-feeder cassette lift
The paper-feeder driver notifies the formatter if either of the paper-feeder media-stack surface sensors
fails to detect the stack surface within a specified period from when a lift-up operation starts.
Paper-feeder presence detection
The paper-feeder cassette media-presence sensor (SR3) detects whether the paper is present in the
paper-feeder cassette.
