about how many pages have printed? As well, have you generally purchased generic or refilled cartridges? This seems to be a low end model with less than stellar reviews for longevity. I'm thinking that a set of HP cartridges might run nearly the price of the printer and that many will consider it not worth the price for higher quality ink...but I don't know your usage. You could try running the cleaning program, clean electrical contacts for the cartridge or buy HP branded cartridges to see if that would work but I'd have to recommend giving up the bargain line of printers. Sometimes they are no bargain over time.
I've exchanged inkjets, one generic, one OEM and the printer is printing "shadows". In other words, faint. I've had this printer for at least a year. It's printing, but the ink isn't printing. Is there anything I can do to the ink or the printer to correct this?
