You can also take off the black cartridge and print with the tri-color cartridge. Another step you can take in this regard is to replace defective or empty cartridges, and give a thorough cleaning to the printhead. HP does not give you any guarantee about the quality of non-HP cartridges. Visit HP anti-counterfeit webpage to check whether your cartridge is genuine.
