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.
