I work on the fujitsu scanner hotline. This message means that the optical unit needs to be replaced, there will be very little you can do to fix this problem.

This is usually a main board fault. re solder the legs of the 2 sets of the 3 transistors on the underside of the mainboard. they are the small ones. or replace the main board. let me know how you get on
