System Error: 42:YZ
Problem Description: Electrical problem (fault, current limit, overheating) in Scan-Axis Motor
Corrective action: Try the following:
1. Switch the power off from the back of the product and disconnect the power cord.
Reconnect the power cord and power on the product.
2. 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 paper 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
Engine PCA.
4. Replace the Scan-Axis Motor. See Scan-axis Motor on page 393.
5. Replace the Engine PCA. See EE Box on page 281.

 

 

Do a google search for the service manual and download it. You will need it.
