Bought a used HP8720. Seller said it had a brand new printhead, but evidently he never used it or set it up. No setup cartridges came with the printer. I get a Supply System Problem warning on all four brand new cartridges I installed. Any way I can get it set up?
I am afraid it does appear to be the lack of set-up cartridges. I was able to locate 3 of four set-up cartridges (no yellow). When these were installed the only cartridge reporting a problem with the supply system was the yellow cartridge. So it is coming up on a non-setup cartridge. The others reported as depleted (which they are).
I was given the old print head as well, and reinstalling it allowed the printer to work, except the head has irreversible ink nozzle clogs and is useless.
If there is no work-around, it seems I need a set of set-up carts -- or at least the yellow -- or the printer is useless.
