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 message "Remove Paper Standard Bin,"
enter the Diagnostic Mode, select Output Bin Tests, select Sensor
Tests and select Standard Bin. 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 is not displayed.

1 Engine Board
Printer fails to display
Remove Paper Standard
Bin message. Output Bin
Sensor Test fails.
2 Output Bin Sensor Flag
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 engine
board.
Check to 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.
