Question about Canon PIXMA MP780 All-In-One InkJet Printer
We have had this printer for a year and has worked fine up until now. I have just changed the cartridges to compatible ones and now the orange error light is flashing. No matter what I do (ie press the reset button) it just keeps flashing and on my computer it just says operator error! I've tried taking the cartridges out and putting them in again with no luck - any ideas what it could be???
Chips have to be reset or they will still show zero. trick with power/resume bottons just gets printer running but will no longer gauge ink level in that cartridge
