Are you using the canon software to download the images and downloading the images through the camera not a disk reader. Sometimes the computer will recognise your camera as a HDD when using the canon software by connecting your camera to the computer with a USB lead. Worth a try.
After searching the net for help and trying many things like unpluging the printer, taking out the ink cartridges, blowing and hooving the printer etc etc and still not having any luck. I tried something myself and it worked.
This is what I did:-
I got several sheets of A4 paper and forced them into the printer just enough to get the rollers to bite. (Printer is off at this stage) Once the paper is in I turned the printer back on and the printer pulled the paper through and out of the front clearing the problem.
Well this worked for and I hope it helps someone else.
The reason for that error code is that there is something in the printer mechanism. Since you say that it happened after changing ink cartridge, make sure there is nothing inbetween the cartridge and ink that interferes, but usually that error refers to something in the way of printing. It is possible that some ink got onto the timing strip when changing ink. Clean that strip if it's the case. More solutions on the video I attached. Hope it helps your printer.
