Re: Inkjet refills not working on HP OfficeJet Pro 8710
We have installed our hpinstantink cartridges in our HP OfficeJet Pro 8710 printer and are getting a "Cartridge Problem" error message. We have taken the new cartridges out and reinstalled them many, many times. We have also done a hard close (turned off printer, unplugged printer, plugged printer back in) with no success.
Please advise. Thank you very much for your assistance.
