It would seem somehow your USB cable plug has got wet and then was plugged into the printer and caused a short circuit in the Logic Board.I have a Canon Pro 1 Pirnter and it's showed error code 9000
High humidity can also cause the same moisture issue..The usb cable is not wet,I checked.
Could I buy logic board from where? Do you know?
I wouldn’t do that unless you want to spend another couple of hundred thousand Dong, because that’s what it will cost....I will take it to Canon Authorised Service Dealer.
The ink absorber full error is a completely different scenario, and it sometimes can be reset, but the only way to know for sure is to look at the nozzle check printed sheet.I have other Canon Pro 1 which has error code 1700. It mean absorber ink full. How can I reset it?
Looking at your nozzle check, it is clear that you have a later model Pro 1 printer that is using Firmware 2.110, and this printer cannot be rest using the normal reset methods, it’s impossible with any firmware above V1.11..i b printed the nozzle sheet. Please see the attach file.
Is it ok or not?
How can I reset ink waste counter?
