4060-xxx 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. FRU 1 System 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 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. 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. Problems with excessive static electricity buildup. FRU 1 Output expander control board cover 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. 2-72 Service Manual
