Printer head nozzles are blocked by dried ink and you might need to undertake cleaning steps to make it run smoothly. If you have already taken necessary steps to clean the clogged nozzles on an inkjet cartridge and you have removed the dried ink off the print head, but still experiencing no print at all then you can clean the metal contacts on the cartridge to verify that the contacts are clean and free from ink. Remember that metal contact and printhead should both be free of any dried ink to ensure a full contact of cartridge to printer for better performance and quality printing.
