If power-cycling does not resolve the problem, try the following :

1. Run an error report in service mode to see if there are any other errors riding with this one. Sometimes one error masks another or other errors may point to a different problem that share a common component.

2. Check the harness between the LSU (laser) and the main board for damage. Sometimes just reseating the connectors does the trick. The service manual should have a point-to-point wiring diagram to locate the correct harness and connectors.

3. Replace the LSU. Seems a bit premature but if the printer took a power hit or ...

4. Replace the main board.
