Hi Voongmc,
Thank you for using the Xerox forum.
I have looked for other solved cases of this error on the device without the flatbed top and the Connecting cable has been an issue in more than 1 instance.
I would suggest that you review the following solution and inspect the indicated cable very carefully. Additionally if a cable is suspect and can cause the symptom, then we can assume that there can be a communications type issue, especially since it passes the power on sequence. So I would not rule out a software reset if available but would leave that as a last resort.
Solution 2 - Verify the ADF cable is fully connected (scanners with a flatbed and automatic document feeder only)
Note: This step only applies to scanners with a flatbed and automatic document feeder (ADF).
The ADF cable is a short cable that connects the automatic document feeder to the body (flatbed) portion of the scanner. On new scanners, this cable may need to be disconnected and reconnected several times to make a proper connection.
- Unscrew the two thumb screws on either side of the connector
- Fully disconnect the cable
- Reconnect the cable, making sure to push the cable all the way in
- Tighten the thumb screws
- If the connector is tight, you may need to repeat these steps a few times before the cable makes a full connection
If the cable is not the cause then the actual document feeding may be another cause so following the above I would perform whatever maintenance is somewhat related and can be found in this linked manual
