It's not looking good, sadly.

LSU stands for Laser beam Scanning Unit and from what I see in my searches there could be dust on the polygon mirror surfaces, or the motor that spins the polygon may be failing or has failed.

The links below show just a couple of other discussions about this;

If you have already cleaned the mirrors but that doesn't help, it looks like the printer is on its way out.

Sorry.

LSU error code Samsung SCX-4725

The LSU error may happen if you replace the toner cartridge with a compatible one.
If you load back the original cartridge the error will be cleared. This is because of the chip board on the cartridge.
I would recommend to re-fill your cartridge rather than buying a compatible.

I'd have a tech give it the once over and then replace the aging, failing printer.
