I have tried for several years to get this printer to do a firware update. I have tried doing it through the printer menu, from my computer via a sub connection. It starts, shows a blank screen on the printer menu and then nothing. I have to unplug for it to come back. Canon support has been no help whatsoever. It has also started not printing due to a bidirectional communication problem and get a message saying my firewall is blocking it, but with no method to fix it.
For the firmware issue, I was told my router may be blocking the connection, but with general instructions on setting up a DMZ or something. No details on how to do that. So no help from support at all. I am connected wirelessly through a linksys router.
For the printing isssue, I have removed and reinstalled the Canon drivers/software twice. Test print prints fine. go to print a document later and it throws an error and wont print. I have Norton 360 as my antivirus.
I am about to toss this printer into the rubbish bin. Any ideas/solutions???
