85% of paper jams are caused by worn rollers . The rubber treads in the rollers wears down, making them smooth, so they won't pick up the paper. Sometimes, they are aged, which also gives them a smoother rounded texture, causing jams. The quick fix is to liven up that roller with a mixture of alcohol and soap. Damp a rag with the solution and wipe the rollers clean with it. That's make them more pliable and the paper jams will cease. If you plan to keep your printer,
Replace the pick-up and feed rollers.
Metal Tab Separation- Pull out your paper tray and examine either end where the paper sits in. If any of the corners are held down by metal tabs, this is your paper feed system. Chances are, you only have one rubber roller or one set of rollers arranged along side of each other. Reach in where the tray goes and feel up. You should feel some rollers. They might be completely round, or they might be shaped like a half moon. Clean whichever part of them you can with the solution, and this should stop your paper jams. It might be necessary to turn them, but don't force them if they don't move freely.
Pickup Roller and Separation Pad-
If your printer uses this paper feed system, you should see a small piece of flat or slightly curved rubber or cork. It would be towards the end of the paper tray, or deep inside the paper loading cavity on top loaders. This 'separation pad' rubs against the paper feed roller, so if you find the pad, you've found the roller. Clean it and your jams should stop.
Three Roller Paper Separation System- Pull your paper tray out, and look for a roller on either end of it. If you find one, clean it. Then look inside the printer where that roller would rest with the paper tray inserted. You'll find another paper roller there. Clean this one also. Finally, look further back or closer to the front of your printer (depending on which way your paper feeds) to find another roller or set of rollers. Clean all of these, and your paper jams will go away
