Paper Deck Cassette Media-Presence Detection; Paper Deck Jam Detection; No Pick Jam 2; Figure 1-51 Paper Deck Jam Detection Sensors - HP LaserJet Enterprise 700 M712 series Handbuch Zur Fehlerbehebung

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)
●
Figure 1-51

No pick jam 2

The PD cassette 1 media feed sensor does not detect the leading edge of paper within a specified
period (including 2 retries) from when the PD cassette 1 pickup solenoid is turned on.
The PD cassette 1 media feed sensor does not detect the leading edge of paper within a specified
period from when the PD cassette 2 media feed sensor detects the leading edge. (3x500-sheet paper
deck only)
