ix6780 printer bricked after resetting wast pad count

Maybe the reason the printer won't turn on is not the failed reset but a failed printhead. Canon printheads can fail suddenly without any warning. A failed printhead might only show in a nozzle check, or give an error screen or flash an error code on the yellow error lamp. In case of a short circuit in the printhead it can prevent the printer from turning on.

You can check if the printhead is the cause by removing it and then try to turn the printer on. If the printer now turns on with a warning about a missing printhead, the printhead was the cause of the problem.

It is not printer head caused this issue that I can confirm. Because I installed another main board and same printer head without any problem.

I have the service manual for the ix4000 and 5000 and also one for the ix65xx series. PM me for details if that might be of any help.
