Same issue for me and the frequency has multiplied in the last two weeks. I am unplugging and plugging in the printer several times a day to keep it going. The printer is connected by ethernet and the blue screen error is always B305DFF9. I have removed and replaced the cartridges several times, AND the print carriage too. Does not seem to help. This has been a rare problem for months, but lately is ridiculous how often it fails. I ran the Scan Doctor utilities and everything is fine and the firmware is up to date.
Solved! Go to Solution.
