Question about Office Equipment & Supplies
Printer is initialising properly, but when i scan / print something, it shows "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.

SOURCE: LSU ERROR shows in display panel
The LSU is the Laser Scanning Unit or "printhead". There is a mirror in there that spins really fast, if the mirror spins too slowly (bad motor, low voltage) it gives an error. Sounds like you would need a replacement LSU. Have the printer serviced.
