When attempting to print on this unit, it would immediately paper jam with about half an inch of the paper making it past the top roller and sticking out. At first i thought it was the top roller not grabbing onto the paper and feeding it the rest of the way out. Using a little alcohol on a cotton swab I cleaned the top roller, without any luck, the paper still jammed. YouTube to the rescue again, this video by sts121, shows what the problem is. There is a small sensor in the unit and I’m not exactly sure what the sensor controls but replacing it seems to have fixed the paper jamming problem. You can also try just cleaning the sensor with an alcohol swab but that appears to only be a temporary fix. Ordering the part directly from Samsung for some reason results in a part that is slightly too big and you have to shave it down a little to make it fit. In the comments section of the YouTube video, Forhorse88 mentions you can buy the part from Digikey.com, part number 425-2449-ND. This part appears to be the same sensor and size, and does not require shaving it down. The printer is just like new now!
11/5/11 An update to this article. The printer came back, so that fix didn’t last long (for me at least). Maybe it was just fluke that it printed after replacing the sensor or it’s a different problem now. I guess I’ll just say, it’s only $4 to have the part shipped to you and 15 minutes of your time to replace it. There’s not much to lose by doing it, and the printer can’t be used when it jams on every page, so I say get the sensor and hopefully it’ll fix your problem.
