Ping me if you don't get anywhere and perhaps we can hookup during my off hours(Not like I have any though being an IT admin hehe) and we could do a remote session and I can see about helping. Installed the Series Media Configuration Tool Version 7.01 for OSX 10.9 (canon doesn't have the media configuration tool for OSX 10.10 listed)ītw, canon phone support didn't help us but perhaps reaching out to them will help for you.Installed the printer driver for the ipf8400s Version 10.11(But I see now it's been removed by canon) so hopefully 10.10 works.Manually deleted the Canon folders that were related and left behind in any directory that could be found such as the Libray\Printers (Mac & Microsoft never delete everything when uninstalling).Here's the basic bullet points of what I did: I think it really contributed to the old drivers that were left behind after uninstall.
I forgot to follow-up in here but I did get it working on our end. Hi Iceland-jessi and anyone else visiting with this issue!
