Check both ends of the Flat cable between the scanner unit and logic PCB. Trim edge of the damaged ends by about 1 mm (if damaged). Clean the mirrors of the LSU. Turn on and try. Service manual can be Down loaded from the internet if required.

LSU error shown how to resolve the problem


Dear
The LSU error may be due to the failure of following
1- harness between lsu and main PBA.- repair/replace the harness.
2-lsu itself-clean optical path inside lsu with dry lintfree cotton cloth.
3-Main PBA- replace the main board.

Thanks.

Samsung 4521f lsu error


The Laser Scanner Unit or LSU is what writes to the surface of the drum. The glass above the cartridge inside the machine could be dirty. The mirror motor in the LSU could be bad or needing cleaned so it spins better. Laser diode could be bad.
