I have a Canon Pixma MG5250 that is making grinding noises on startup, and shows a variety of printer error codes. I really don't need it to work as a printer (have a faster, cheaper-to-run laser printer), but would like to use the scanner. Can someone suggest a solution, preferably permanent? Like I say, I don't need to print, so the solution can be destructive and irreversible if that's what it takes.
