This points to the fuser unit lamp being broken.
You can try a trouble reset by switching the machine off with the main power button only (in the flap on the front in the square panel), then whilst holding down the UTILITY/COUNTER button, turn back on. When a black circle appears in the top right corner of the screen you can release the UTILITY button.
When TROUBLE RESET appears on the screen press it. The display should say OK.
Then power the machine off and on again. If the code reappears you need a service call to make sure everything is same as the fuser code appears for your safety.

The problem could be the laser that scans the image or the detectors that see the colors. It could also be a problem with the power supply or the main board. This is not going to be cheap. If you want to continue, you should download the service manual.
