Paper jams on Canon MF3240

A month or so I started experiencing ever more frequent paper jams with my Canon MF3240. The jams occur at various points in the paper feed cycle, and the paper itself doesn't seem to be jammed, but the error light goes on and printing stops. After clearing out all the paper in the print path the printer starts up again... and often goes into another jam state before cycling through the print job.

The manuals are useless, as was the response from Canon. I'm hoping to find someone on line who can shed some light on the problem and a possible fix.

Start with the paper itself. Make sure it is in the machine properly. Here is a short guide on a few things to check:

How can I prevent paper jam 0207 on canon 2230


Although paper jams occur because of dirty pickup rollers I have found that jams occur frequently because of solenoids in the paper feed mechanism (the assembly that the paper trays fit into). There are two of them and over time the damping foam on the levers get sticky causing the lever to operate late which causes the jam. As a fix I remove the damping foam and put insulation tape on the lever making sure the solenoid works by using a 12v bench psu before reassembling. You will need service manual because Paper Feed mechanism removal is a little complex.

Paper feed problems in Canon Laser Jet Printers are caused by these solenoids mainly in Duplex mode. P3005dn's etc.
Hope this helps solve yr problem.

Tip

Canon ImageClass MF3240 paper jam fix


The Canon ImageClass MF3240 continues to show "paper jam" error even if someone followed all the possible fix to remove the jam. After clearing the paper in all access doors (both front and back), the printer still gives the paper jam error. Also, if you have tried restarting the printer several times to no avail and the red light keeps blinking, here is the fix to what is most probably been causing the paper jam problem of Canon ImageClass MF3240.

1. Turn off the printer and pull out all plugs and power cord that is attached to your printer.

2. Remove the paper tray at the bottom and let the printer lie at its back so that you can see underneath.

3. Get a flashlight and look closely for the sensor located underneath the printer. The sensor is located in a small square hole, just above the small black plastic "lever" (looks like a small hockey paddle) on the left side of the gray rubber roller. Move the lever so that you can freely look closer on the hole.

4. Notice because there could be a tiny paper shred stuck inside and this causes the sensor to detect a paper jam.

5. Get a small tweezer to remove that paper out.

6. Next, let the printer stand normally and return the tray back.

7. Re-plug all cables and start your printer. That's it!

Canon MF3240 Paper Jam - No Real Jam


try this
  1. Turn off the printer.
  2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
  3. Also open the back cover of the printer if this model has one.
  4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
  5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
  6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
  7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
  8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
  9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
  10. see alternative if the problem is still not solved.



alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

Paper jam is showing on printer info., but ther's no paper jam.


Ok this issue ussually occurs when the roller feed doesn't load the paper due to the following reasons:
1. If your printer is operating for  more than two years or so... gear tear will most likely to occur. If you can open the printer and check everytime the printer initiates after power on ad if the roller feed doesn't rotate but the leftmost rotary gear with the encoder wheel rotates, the gear is most likely to be loose even there is no paper jam nor dust contamination on the rubber and paper feed mechanism. You need to replace the said gear with the encoder strip . A simple solution would be aplying epoxy resin so it will be fixed on the rotary shaft. It may last for quite sometime but better yet replace the gear.
2. The feeder rollers might be dirty and needs to be cleaned and greased the gears.
3. Probable defective print cartridge. Try replacing it with a new one. 

But based on the items above, if your printer is operating more than a year or two, and frequent paper jam is being experienced, gear tear near the motor is the culprit.

Trouble with paper feed


Frequent jams are because either scanner picks up more than one paper or does not pickup at all. If scanner picks up more than one paper, then paper is sticky. If the paper is thin, it can pick up two at a time. Fan the papers so that they are not sticky.

Paper at the point of entry into the scanner must be crisp. If folded or 'dog-eared' trim it. Rotate the paper if any other side is crisp, roate the image later.

Clean all the rollers thoroughly, the pickup roller, retard roller and other rollers in the scanner. One can rotate the inner rollers and clean totally, not just waht is seeable area. If the rubber is worn out, it must be replaced. TRy a single page to check if the rubber is okay. Jarring noise is because the motor is 'stopped' and cant rotate because paper is stuck. This can affect motor/inner parts, but is designed for normal use.
