I bought ink cartridges on line that initially worked in my printer. Over time, and only when printing documents from an online source the printer quit working giving me a printer cartridge not recognized message.
I currently have all filled cartridges in my printer and it has selected the magenta cartridge as not recognizable. When I put another similar magenta cartridge I get the same message. When I put in a cannon cartridge, the light goes indicating acceptance of what is an empty cartridge.
How do I overcome what is clearly Canons control over which cartridge I use in my printer? Is this firmware that has been updated automatically to block use of other than canon cartridges? This is a royal pain in the butt and would cost me a mint to use the over priced canon supplied cartridges.
