The paper deck controller 3 determines a PD cassette 3 lifter motor failure and notifies the formatter
through the DC controller when the PD cassette 3 media stack surface sensor does not detect the paper
surface within a specified period from when the PD cassette 3 lifter motor starts rotating.
Paper deck cassette media-presence detection
The paper deck controller detects whether the paper is loaded in the cassette by monitoring the PD
cassette media out sensor.
The cassette media-presence detection is not performed during Sleep mode.
The paper deck controller determines a media-absence and notifies the formatter through the DC
controller when the PD cassette media out sensor does not detect the paper.
Paper deck jam detection
The paper deck uses the following sensors to detect the presence of paper and to check whether paper
is being fed correctly or has jammed:
●
PD cassette 1 media feed sensor (SR1)
●
PD cassette 2 media feed sensor (SR81) (3x500-sheet paper deck only)
●
PD cassette 3 media feed sensor (SR91) (3x500-sheet paper deck only)
