The error would be stating LSU. It stands for Laser Scanning Unit.
The LSU error signifies that there is an issue with the laser scanner, the part that helps making prints.
There could be an issue with the laser or perhaps the polygon mirror, maybe the sensor or a combination of these that needs to be fixed.

In the User's manual it is stated:
To turn off power and wait for 20 seconds. Then turn on the power again.

If the problem is still there then you will need to call for service.
The service tech will recommend a new laser unit or control board.

Best of luck!
