Setup, Compatibility & Care
To install, gently remove the protective tape from the print head, ensuring you do not touch the electrical contacts. Insert the cartridge into the designated black ink slot of your HP printer until it clicks securely into place. This cartridge is compatible with the following printers: HP Envy 5640 e-All-in-One, 7640 e-All-in-One, 5540 All-in-One, 5546 All-in-One, and HP Officejet 5740 e-All-in-One. For care, keep the cartridge in a cool, dry place away from direct sunlight before installation. If the printer remains unused for long periods, perform a standard print head cleaning cycle via the printer software to prevent ink drying.
