This is a "call to arms" for all of you Canon customers who have had this problem and have had their printers disabled because of it. Please respond with the model of your printer and if you were able to fix it, what you did to fix it.
We need to put pressure on Canon to respond this product defect. It appears to be bad firmware that does not allow the user to override the problem and to continue to use the printer even in a degraded mode. From my investigations the problem is NOT a printhead issue - no way one can be printing fine and then have this error alert without having changed the printhead or ink cartridges!
Canon, PLEASE take this issue seriously and provide a solution across the affected models. If nothing else there should be a trade-in allowance for those printers that have been affected by this product defect.
I have had many Canon printers because they have superior functional specifications. I want to be able to continue using Canon products but only if I can have confidence that this product defect will not destroy my investment.
If Canon is unresponsive our next step should be to aggressively publisize this product defect on social media and on major product vendor outlet sites as negatives reviews.
Forum Users, please reply with your affected model number(s) and with details of any succdessful fix procedure.
