1. Use TECH mode("cover sensor test") to check cover switch operation. Check and replace switch if necessary. 2. Replace the front cover. 3. Replace the Main Control board or HVPS as necessary.


===================================

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 a 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.
