SAMSUNG ML-2010PR printer problem

Zdravo svima, izvinite za los srpski, imam veliki problem za Samsung ML-2010PR printerom. Povuce list oko 5 cm, onda stane i svete dve diode, trepte na 4 sekunde. Ispada prozorcic na monitor na PC i kaze LSU error, citao sam da je nesto oko laserske diode, ali mnogi malo informacija na netu okolu to. Ima li neko ideja sta je problem i kako moze da se ukloni?
Hvala puno.

sa neta:
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

znaci probaj driver promjeniti,najbolje probaj ga prikljuciti na nekom drugom kompjuteru sa drugim USB kablom.Zatim probaj toner promjeniti.Taj LSU ne znam kako izgleda kod tog printera.Ako je kao i kod ostalih printera stavi kap lanenog ulja kad rastavis motor sto okrece metalnu kvadratnu plocicu koja rasprsuje svjetlost lasera.To ti je jedini motoric u laserskom sklopu.
Prvo prije svega dobro pogledaj da nema kakav komad papira da nije osto u njemu pa ne da papiru da prodje prema grijacu..
