When moist, such as ink, creates a short circuit between two contact points in the printhead of the ribbon cable that connects it to the main board, then a small fuse on the mainboard blows. The error code the printer gives is 031006. The fuse on the mainboard is marked with F1 or F301 or something similiar. It is small!! I can’t tell you where it’s located as that is different for every different mainboard version.

Take the covers off your printer, disconnect all cables off the mainboard, take the mainboard out, spot fuse F301 and measure its continuity with a multi meter. If the meter does not beep: bingo. Replace the fuse, assemble everything, your printer works again. Are you confident with a screwdriver and a soldering iron? Then you can do it and save yourself a $100 new mainboard. If you found the fuse to be properly working, then don’t touch it and check all ribbon cable connections and clean all contact points between printhead and mainboard instead. https://www.youtube.com/watch?v=VoxwMqZNDv8
