I have the same exact problem that occured after a paper jam. I have contacted support twice. The first time I was told to use borderless printing in my printing prefences. It did work even though you get a warning not to use it with plain paper and it worked when I tested it while on the phone with the support person. When I tried it afterward, it no longer worked. What's more, it cannot be used with the paper saving option or any other option other than standard. It certainly cannot be used with duplex printing. So I called support again thinking I somehow misunderstood or set my preferences incorrectly. This time I was instructed to uninstall the printer and reinstall it but using the downloaded drivers, not Microsoft drivers. Then I was told to set my preferences the way I wanted them BUT if printing from the internet or using adobe, use the "shrink to fit" option (not to be confused with the "fit to page" option on PageSetup tab in your Printer preference window found in Control Panel Settings) Well this worked again, while on the phone with the support person but does not work every time. I am pretty much done with Canon. I would just like to set my preferences and forget it and have a printer that works but that is not to be. On the upside, I am not experiencing the frequent paper jams anymore. I don't know if it is the printer, the drivers, the firmware or Microsoft. Very frustrating. As long as I am complaining I would like to add that ink for this model is very very expensive.
