Hi Julius
I have a different PIXMA model to you, but it too gets a bit stroppy from time to time. This is sometimes prompted by a Windows update, which can cause device driver issues. My usual remedy, which more often than not does the trick, is to completely uninstall the printer and its driver then do a clean reinstall. For the reinstall, I usually ignore the supplied disk and go to the Canon support site for the install software, which provides the latest drivers. A couple of "how to's" in links below for printer/driver removal if you are unsure. (These for Windows 10). Good luck.
