Output bin sensor standard tray service check

Service tip: If the output bin standard tray fills up and the bin full sensor fails to post the Remove
Paper Standard Bin message:
1.
Enter the Diagnostics Mode.
2.
Select Output Bin Tests.
3.
Select Sensor Tests.
4.
Select Standard Bin.
5.
Check the sensor and flag for proper operation.
If you find no problem with the sensor and flag, continue with the service check.
Service tip: Be sure the flag is correctly installed. The output bin sensor is a normally closed sensor
with the sensor flag down. Therefore, unless the flag is in the up position or out of the sensor slot, a
Remove Paper Standard Bin message does not display.

Output expander service check

Service tip: The majority of the mechanical components can be observed during operation by
removing the left, right, and system board covers. The output expander functions without the covers
installed.
Make sure the option is correctly installed before attempting to service the unit. No jumpers should
be installed at connector J6 on the output expander board.

Action
Check the voltage at J11-1. It measures +5 V dc when the flag is in
the sensor, and 0 V dc when the flag is out of the sensor. If the
voltage does not change, replace the sensor cable assembly. If this
does not fix the problem, replace the system board.
Make sure the correct flag is installed. Check the flag for damage or
improper operation. If incorrect, replace the flag.
Note: A broken or improper operating sensor flag causes a Remove
Paper Standard Bin message to display before POST completes and
cannot be cleared.
Action
Check the output expander control board cover to make sure the
ESD brush ground lead is firmly attached to the output expander
frame. Also make sure the ESD brush is not loose.
