Oh, BTw it is a HP photosmart C7280 AIO purchased last year from Office Depot.
Getting an error message: Oxc19a0020 saying ink system failure. We are using all OEM hp cartridges in the printer. Never have used any noname inks. We have removed and installed all the color inks and the black ink to no avail. Anyone out there with some help would be appreciated. Bill
