Electrical problem (fault, current limit, overheating) in Scan-Axis Motor
Try the following:
1. Switch the power off from the back of the printer and disconnect the power cord. Reconnect the power cord and power on the printer.
2. Open the Window and check for any visible obstacles restricting the movement of the Carriage Assembly. Remove any obstacle to let the carriage move freely along the whole scan axis. If there is a wrinkled mass of media inside the paper path, raise the pinch wheels (using the media lever) and clear the obstruction.
3. Check that the Scan-Axis Motor cable is not damaged and is correctly connected to the Main PCA.
4. Replace the Scan-Axis Motor.
5. Replace the Main PCA.
