Same issue here. Getting message that the printer wants SETUP ink cartridges.
I was trying to get rid of an "Ink System Failure" message with code 0xc19a0042. Did extensive cleaning of the printer, and also tried the working printhead from an HP Photosmart 7525, which uses the same printhead. Have all new HP ink cartridges. Kept getting "Incompatible Ink Cartridge(s") message. Finally did a "semi-full" reset, and now it wants the Setup cartridges.
Thanks for any help.
