I have zero actual knowledge on this subject, but it is hard to believe that Canon would go to all of this trouble to record the use of refilled/CIS carts and have you agree that such use voids the warranty and then discard that information just because a set of OEM carts was reinstalled. I'm afraid that when you agreed to void the warranty that this fact was permanently recorded in the printer's memory and that you have forfeited all claims for warranty repairs on that printer.narmenia said:Can anyone help in restoring ink monitoring on an ip4300?
I need to send the whole unit to canon (philippines) for a head replacement.
