Antwoord op "Why does my printer not recognize a new print cartridge?"Hi..my printer (model: HP DESKJET INK ADVANTAGE 2520 hc) cannot detect the black ink. The error appears to be ink incompatibility and not do not recognize the ink at all. I already tried to remove and reinstall the cartridge, turn the power on, plug and unplug the cable and connection for quit amount of time but still the error still showed up. I also tried to wipe the cartridge and its connector (print head i think) using non fiber tissue and absolute alcohol, error dissapear for a few seconds, indicator showed full black ink at this point but then the error reappear again. I also already replacing to new black ink cartridge but it still flashing an empty ink error. Can anybody here help me to sort the things out? What should i do?
