Stapler/Stacker Failure Detection - HP LASERJET ENTERPRISE M725dn Troubleshooting Manual

Stapler/stacker failure detection

The stapler/stacker controller determines a motor failure according to the condition of the following
related part:
Jogger motor failure
●
The stapler/stacker controller determines a jogger motor failure and notifies the formatter when it
encounters the following conditions:
The jogger guide in home-position does not move from its home-position within a specified
◦
period from when the jogger motor starts rotating.
The jogger guide when out of home-position does not move to its home-position within a
◦
specified period from when the jogger motor starts rotating.
Alignment-alienation motor failure
●
The stapler/stacker controller determines an alignment-alienation motor failure and notifies the
formatter when it encounters the following condition:
The home-position of the output upper roller keeps detecting for a specified period from when
◦
an alienation operation of the output upper roller starts.
The home-position of the output upper roller is not detected within a specified period from
◦
when an engagement operation of the output upper roller starts.
Stapler motor failure
●
The stapler/stacker controller determines a stapler motor failure and notifies the formatter when it
encounters the following condition:
The home-position of the stapler is not detected within a specified period from when the
◦
stapler motor starts rotating during a WAIT period or during recovering from a jam.
The stapler is not primed even though the self-priming has been executed for a specified
◦
number of times during a stapler self-priming operation.
The stapler/stacker controller cannot determine if the feed motor has failed; therefore, a jam occurs
when the motor fails.
