Topic: problem with firmware
Hello, I found another post with this problem, so I decided to ask.
While updating the firmware of my printer XYZPrinting duo, there was a power surge in my region and the printer turned off after re-power the printer does not turn on and two bars appear on the printer display, after reading some materials saw that you can do not turn off during the upgrade.
Now the big question, is no fix this problem?
How should I proceed?
Thank you for your attention
