Paper jam in the Canon PIXMA MX 452

Here is some tips to avoid paper jam..

• If your printer has a paper tray do not fill the tray to capacity. If you're encountering frequent paper jams, reduce the amount of paper you place in the tray each time it is filled.

• Make sure you or the tray feeding the paper into the printer is aligned properly and the slider used to hold the paper in place in the tray is snug with the paper. Many printers have sliders that allow different types and sizes of paper to be fed into the printer. If the slider is not properly positioned it can cause paper jams.

• Use standard office paper; folded paper, paper with labels, and specialty paper such as hard bound paper can often cause paper jams. If you're uncertain with what paper you should use with your printer your printer documentation will list the paper compatible with your printer.

• Do not mix the paper you're feeding into the printer at one time. If you need to change the paper or size of paper being used removed any other paper currently in the printer before inserting the new paper.

• If your printer uses a slot or tray for the paper make sure to not push the paper too far into the slot or tray.

• Examine the printer for any previous stuck paper in the printer. Previous paper jams, torn paper, printing labels or other foreign objects in the printer can cause reoccurring printer jams.

Unlatch and pull out the paper tray. Try pulling out the sheets in the middle of the "half stack" first. You should have less friction there. While you have the paper tray out, examine the rectangular cork paper separator strip on the right-hand side of the back corner. If it's worn or missing, that would explain how the jam got started.

Follow these steps :
1.1
Remove all paper from the trays. This will prevent further jams during the clearing.
2.2
Remove the covering to the printer's outer case to expose the jam. Locate the jammed paper to ensure there is not another problem causing the stall.
3.3
Pull gently on the jammed paper, taking care not to tear it. In most cases, this will remove the jam.
4.4
Press the flashing "Printer Jam" button. This will allow the rotors to turn and facilitate the release of the jam.
5.5
Turn off the printer and firmly pull on the jammed paper. Be careful not to tear it.
6.6
Remove remaining paper shreds. if a tear occurs, remove any residual paper that may hamper printing.
7.7
Refill the paper tray and try printing again. If the jam persists, repeat the process and search for more paper.

You need the pick up rollers replaced. Call your service centre to replace pick rollers as these are feeding the pages crocked

Look at the paper path very carefully. There might be a piece of paper that got torn off and is either jammed up in the fuser or the registration assembly.

It may be this simple:

1- as silly as it may seem, are you sure the size  is correct, if it is a letter size paper and it says legal, it will jam. open the paper tray and make sure the guides are snug againgst the paper,

does it say letter (or legal) for the tray you are going to use, if they do not correspond then look behind the tray inside the machine, is there a paper jammed in the back?

 

Or not so easy

2-You are having a sensor problem, take a look at the duplex tray,

pull it out and look at the sensors ( black little levers that stick out) are there any pieces of paper, can you move them and they spring back into place?
