Output Bin Sensor Standard Tray Service Check - Lexmark T640 Service Manual

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.

Action
Check the voltage at J6-1. 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.
