It the ink smudging right at the edge of the page? If so, you may have ink built up on rollers and in the printer's transport mechanism. Use a moist paper towel or wet wipe and clean the interior of the printer including the feed rollers. Another possibility is subtle head strikes as the print head moves onto the paper due to curled paper issues. Low humidity is one variable that can be causing curled paper. Lay out a sheet of your paper (printing side up) on a flat table. Is it flat or curling at edges forwards and away from the table? If it shows demonstrable curl, the print head may be catching the paper at the edges as it moves onto the paper and thus leaving an ink smudge due to a head strike. Try decurling the paper before printing. Wrap and roll the curled paper in the direction opposite to the curl around a 1.5 - 3 inch diameter tube to de-curl the paper.
thanks Mark it is the edge of the page
I'll try your suggestions

DO you use OEM carts?
If you are using refilled OEM carts, you may have one of more leaking ink due to a not well sealing fill plug.
Cleaning cycles will exasperate the problem which is excess ink buildup on the print head nozzle plate.

I use only Canon ink carts
Then check that your paper is PERFECTLY flat! If the corners of the trailing edges are curled, even slightly, you will get head strikes which = smudges.

I hope that helps.
