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 feed problems will go away

Please see this solution from Canon. It is recommended you check your manual for the proper procedure for clearing paper jams. Incorrectly removing jams could damage your printer. Trust the following helps resolve your current issue.

If you do not have a manual it can be downloaded from here:

Issue: More than one sheet of paper feeds while printing


Solution: Clean the paper feed rollers using the MX300 operator panel

Cleaning the Paper Feed Roller (Roller Cleaning) Clean the paper feed roller if paper is not fed properly. Cleaning the paper feed roller will wear the roller, so perform this only when necessary.

1. Make sure that the machine is turned on, and then remove any paper from the Rear Tray.

2. Clean the paper feed roller.

(1) Press the Menu button repeatedly until MAINTENANCE appears.

(2) Press the or button to select ROLLER CLEANING, then press the OK button.

The paper feed roller will rotate as it is cleaned.

3. Repeat step 2 twice.

4. Open the Paper Output Tray.

(1)Put your finger in the rounded indent beside the Paper Output Tray and open it gently.

(2) Open up and set the Output Tray Extension completely by pressing down the hollow on its front side.

5. Make sure that the paper feed roller stops rotating, then load three or more sheets of A4 or Letter-sized plain paper in portrait orientation in the Rear Tray.

Set the Paper Thickness Lever to the left.

6. Repeat step 2 three times.

The paper cleans the paper feed roller as it feeds through the machine.

If the problem is not resolved, wipe the paper feed roller (A) located on the right side inside the Rear Tray with a moistened cotton swab or the like. Rotate the roller (A) manually as you clean it. Do not touch the roller with your fingers; rotate it with the cotton swab.

To clean the paper feed
Machine button

1. Turn the printer off and open the access cover.
2. Look for any obstructions in the paper path and remove them if necessary. (It is possible to move the carrier assembly with the power off.)
3. Turn the printer on, load some paper, and press the Form Feed button.
4. Watch the paper as it feeds through and try to determine where the jam is occurring.
5. Check to see if all the rollers are turning.

If all the rollers are turning, there may be something in the feed path that you can't see. Go to step 6.
If not, there is probably a feed motor or a gear problem and the printer may require service.
6. If the paper is jamming under the carrier assembly, you may be able to fix it using the manual feed slot.
7. Turn the printer off.
8. Take a #10 envelope and feed it through the left side of the manual feed slot until it comes right through the printer to the back of the exit rollers.
9. Move it up and down first, and then slowly move it over to the right side. If something is stuck under the black guide plate, this may work it loose.

Clean the pickup rollers with a damp cloth, and dry the rollers with a clean part of the cloth. If it is still feeding paper in scew, then there could be something stuck inside the printer.
