All HP printer cartridges are covered by a manufacturer’s warranty so should you find your cartridge is defective, you can return it for a replacement. While HP doesn’t normally accept replacements from consumers, it does have a system in place with its retailers to make the process as hassle-free as possible. After you determine that the cartridge is covered by the warranty, simply take the cartridge back to the place you purchased it from, along with the required information form and a sample of a print job using the defective cartridge.
