My canon pixma mp495 printer keeps sayig papaer jam and pulls the paper in on one side only


There may be a bit of paper or a foreign object (paper clip, staple) stuck in the feeder rollers inside the printer. Lift and open every panel that you can and have a good look with a torch. pick out any foreign material you find.

Keeps saying there is a paper jam


Unplug the printer and open all the access panels. Using a small flashlight may help. Carefully check all areas inside the printer for a stray piece of paper logged somewhere inside. You may need a small pair of pliers or tweezers to remove the piece of paper.

When clearing jams ensure you find the entire piece of paper that was jammed in the printer.

When your done, be sure to securely replace all parts removed from the printer and properly close all the access panels.

Keeps having paper jams need help


Protect yourself from shock. Disconnect the power cord from the back of the Canon Inkjet Printer. This is an important step when working inside ANY electronic device. Unhinge the back access panel of the printer. It seems repetitive to say this, but this door will be in the BACK of the printer.

Look through the opened back panel and look for paper. Remove any and all paper you find jammed there. Close the back access panel. Make sure that it latches into place and looks the same way that it did before you opened it.

Find the front or top access panel. This is the panel you would lift to change ink cartridges. Open this access panel. If the carriage that holds the ink cartridges moves, then you forgot to unplug the printer, go back and do that now. Look for paper that may be jammed in this area of the printer.

Remove any paper you find jammed here. When pulling from the front there will be resistance from the paper feeder. Pull slowly or the paper will rip and create a more stressful problem.

Close the front access panel. Make sure that it falls or latches back in place. It should look the same way that it did before you opened it.

Plug the printer's power cord into the wall outlet, and attempt to print again. If the printer prints the job, then you have successfully removed the paper jam.


Following the steps above you can clear the paper jam issue on your canon inkjet printer installed on your Windows based PC.

Hope that helps.

Thanks for using fixya..

Issue
During printing, the paper becomes stuck in the all-in-one and the error message 'Paper Jam: Clear jam, and then press Enter' displays on the control panel display.
Solution
Use the following instructions to clear a paper jam from the product:
Step one: Check for and remove any loose paper from the In tray
Do not try to remove jammed paper from the In tray. First remove any loose paper from the In tray to avoid worsening the jam.
CAUTION: Always try to remove jammed paper from the back of the printer first to avoid mechanical damage.
Step two: Clear the jam from the back of the printer
Follow these instructions to clear jammed paper from the back of the product. If the product is equipped with a two-sided printing accessory, skip to that section.
Remove the rear access door to clear the paper jam

1. Remove the rear access door by pressing the buttons on the side of the door and pulling it toward you.
Figure 1: Removing the rear access door
Rear access door
2. Gently pull the jammed paper out of the rollers.
WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the product. If all the pieces of paper are not removed from the product, more paper jams might occur.
3. Replace the rear access door. Gently push the door into the all-in-one until it snaps firmly into place.

Remove the two-sided printing accessory to clear the paper jam

1. Remove the two-sided printing accessory by pressing in the buttons on the sides and then pulling the accessory toward you.
Figure 2: Removing the two-sided printing accessory
2. Gently remove any jammed paper.
WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the accessory. If all the pieces of paper are not removed from the accessory, more paper jams might occur.

Figure 3: Opening the two-sided printing accessory door

4. Close the cover of the automatic document feeder, and then reattach the document feeder tray.

Step four: Verify that the print carriage can move freely
Follow these steps to try to move the print carriage.
CAUTION: Do not force the print carriage to move if it is out of plain view or feels stuck. Forcing it may damage the printer.

1. With the product turned on, open the print cartridge access door. The print carriage might try to move into the access area. If so, allow it to move to that position.
2. Without turning off the product, unplug the power cord from the back of the product. Unplug the power cord from the power source. The power cord must be unplugged to allow the parts to be moved by hand and to reset the paper feed mechanism, without the risk of an electrical shock.
3. Looking in through either the print cartridge access door or the output paper tray, make sure the print cartridges are locked into the carriage and have not come loose. Also, make sure that there are no obstructions under or around the carriage to block it from moving.
4. Make sure the print carriage can move freely across the width of the product by gently pushing the carriage to the left and then to the right. Clear any obstructions found.
You may have to reach through the output paper tray to access the print carriage.
5. Close the print cartridge access door and plug the power cord back to the back of the product. Plug the power cord into the power source.
6. Press the On button to turn on the product.

Step five: Reload and test the printer
After you have removed the jammed paper, make sure the product is still functioning properly.

1. Reload the product with plain paper.
2. Peform a self-test by pressing and holding the RESUME button on the control panel until the product begins printing. A test page prints.

Step six: Service the printer
If you have completed all the steps listed above and are still experiencing a problem, service the product.
