Question about Canon PIXMA MX340 Wireless Office All-in-One InkJet Printer
Removing the covers is not the answer. Most jams on rear feed printers/faxes are due to some object falling in the sheet feeder. When you pull the paper back out (Very slowly) of the sheet feeder after it has jammed , you will see a nick in the paper. This is because the paper is hitting something and cant get past it. put the paper back in the sheet feeder and the nick will indicate where the object is. Find a large paper clip and unwind it and bend the top of it to 90 degrees. use this to hook the object out and then tip the printer upside down and watch it fall out. Good luck

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
