Problem began with a paper jam. We cleared the jam by removing the ink cartridge then reloaded the paper. We then got an "LSU error". Then after powering off for about 15 seconds, the printer works but we're getting three horizontal lines of smeared ink on each printed page. Can something be cleaned? If so, where?

Re: Samsung ML 2010 Laser printer
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.

I also have the ML-2010R and I also had the paper feed problem. with warnings about paper jam around toner cartridge.
After a bit of reading and people mentioning the big roller that picks up the sheet of paper and that it needs replacement; I decided to carefully try to clean that rubber roller.
I used a brush and medical alcohol to clean the roller. After letting the roller dry I put in some paper and tried to print again and for me it works like a charm!
Is it connected directly too the computer or to a network?
What it sounds like is that you are having a spoiler problem, the computer is intialized but its not getting the info to print. Or it could be a printer malfunction, something mechanical isn't working right in the printer. If you've removed the ink cartridge and replaced it, it could be out of place or not seated right. Other components could be locked up. If the light goes red could you tell us what the error message is? And have you looked at your user guide for information on possible errors?
