I have recently (5 weeks ago) bought a HP479FDW. Nothing has moved the printer or nudged it or anything. There has never been a low toner warning. All of a sudden, it comes up with this error "The indicated supplies are not communicating correctly with the printer. Try reinstalling the supply to continue.".
Have reinstalled the toner in question a few times. Hasn't worked.
Having looked around this forum, it seems it is not an isolated incident. Seems to be a problem with the starter CYAN cartridge for the 479FDW. Can this be looked into?
If it is running out of toner, should it not give us plenty of warning? I suspect the toner is not out as the other cartridges are still at least 65% full. What troubleshooting steps can I take to identify the problem?
