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.

LSU Error keeps showing


LSU stands for Laser Scanner Unit. Depending on the model this should come up only if the services used required scanning such as copy, fax sending, scanning.
nevertheless if this is a continuous message you might need to check the connectors within the scanner which I advise an field call.

The printer shows LSU error, When i Turn it of after 2 or more hour I can print max 3 copies and then the same error appier (LSU error).


Hello my friend this is Laser Scanner Unit error and this is probably cause if the polygon motor in the LSU does not rotate.The LSU’s laser beam is
functioning properly.You can try unplugging the machine for 3 minutes and plugging back in before you do anything else.If this does not fix it you will need to have it serviced.

Samsung scx-4521 f


if it's a vertical line in scanned pictures, it's probably a dust bunny on the scanner head, if it's only on printed pages, it's probably a dust bunny on or in the laser assembly or between the laser and the photosensitive drum. if cleaning doesn't get rid of it, you could have a defective scanner head or laser assembly, or a scratch on the photosensitive drum.
