My canon pixma g3400 i refilled ink and command to refill pipes. After that it stoped working.
I have tried a few ways i found online now it is not starting in service mode at all it just freezes
When i start it normal i get 7 flashes and no functions
In safe mode it does not link to my pc or able to scan
What can i do to fix it or is it corrupted suddenly?
Please help me if you can. I really need to fix it
