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?
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?
