Samsung ML-2010 LSU Error

I've been searching Google for possible combinations of Samsung ML-2010 laser printer LSU error, and I'm at a loss. We've had the printer for about 6 mos and it has worked very well, until recently it would 1 or no pages, partially feed a new sheet and stop. The PC displays the I'm experiencing an LSU error. The directions say to power off the printer for 10+ seconds and retry (this is not working, no matter how long I wait). The last direction is to contact a Samsung repair representative. Any thoughts? I'd love to repair this on my own if at all possible. Thanks for your time. dear sir samsung scx 4521F, i have same problem lsu error, can i repair myself?

    Ich habe erst seit 3 Monaten ein Samsung SCX-4521F Multifunktionsgerät mit Laserdrucker. Der letzte Druckvorgang wurde abgebrochen und seither zeigt er mir LSU-Fehler an, kann weder drucken noch kopieren! Hatte bisher das Gerät mehrfach ausgeschaltet, den Computer resettet ohne änderung. Nach zweimaligem Telefonat mit der Samsung Hotline weis ich immer noch nicht weiter, weil kein Techniker zur Verfügung steht. Warte seit 2 Tagen auf Rückruf!

    I do not recall to have an error-message that displays a broken LSU but have the same paper problem. After one page the printer partly feeds another page and then stops. If I then open the front-door and pull back the all the papers and then put back in it works again, for one page.

    Does anybody have a solution?

It sounds as though the laser went out. Its not too bad to replace, but you would need a service manual. Be sure you can get the part first, I checked my usual suppliers and could not find one. If you do replace this yourself, be sure to follow all the safety procedures.

Lsu error shown on printer display pannel itdo not work with any functions . can some bodyhelp me plzz

The most likely cause is the Laser Scanner Unit (LSU). They cannot
usually be repaired, parts are impossible to find. Unfortunately there
is no real alternative to replacing the LSU, if that does not fix the
problem the next most likely cause is the Main Board. Both are
expensive so you might want to see how the cost of the LSU compares to
a replacement printer. You could google for a Samsung ML-2010 Laser
Scanner Unit to compare prices.
Alternatively get a quote from a repair shop and compare that with
buying the LSU yourself.

LSU means "Laser Scanner Unit". That is the part that actually "prints" the image on the drum before it goes to the paper. If the toner (not ink) cartridge is in good condition, then you need an Authorized Service Center to replace the LSU assembly.
