Laser Scanner Unit or LSU is what writes to the surface of the drum. The glass above the cartridge in the machine may be dirty. The mirror motor in the LSU could be bad or needs to be cleaned to spin better. The Laser diode may be faulty.
This is not a user-serviceable issue. You will need to contact Samsung for service. You can do it online via Samsung website or contact the vendor to see who will they appoint to service the printer to, especially if it is still under warranty.

Dear Sir,
Welcome to fixya,
The most likely cause for this error is the (LSU).
Shut off your copier and let it rest for 10 minutes.. and turn back on,It may solve your problem if it is not solves your problem may be Laser Scanner Unit dead & it cannot be repaired, parts are impossible to find. Unfortunately there is no real alternative to replacing the LSU.
I think it helps.If you have any confusion regarding this issue leave a feedback we will glad to assist you.
Have a Nice Day!
LSU stands for Laser Scanner Unit ... you normally get 2 different kind of errors with LSU ...
LSU Hsync or LSU Motor Error ...
If you get this error, it means that the Laser Scanner Unit has gone bad and the only way to get it fixed is to get the printer repaired ...
