Chips, Printer Messages & Installation

Installing: open the cartridge access door and wait for the carriage to move to the center. Press down on the old cartridge to release it and pull it out. Unwrap the new one, pull off the plastic tape by its tab without touching the copper contacts or nozzles, and slide it into its slot at a slight upward angle until it clicks. Close the door and print the alignment page if prompted.

"Cartridge problem" or "incompatible cartridge": remove the cartridge, wipe the copper contacts with a dry lint-free cloth, check that all the tape is off, and reseat it until it clicks.

Streaks or missing colors: run the printhead cleaning from the printer's Tools menu or HP software. The printhead is built into these cartridges, so a cartridge that stays streaky after two cleanings is the likely culprit.

Remanufactured vs. Compatible vs. Original

Original (OEM) cartridges are new from the printer brand and cost the most. Remanufactured cartridges, like this one, start as genuine original shells (including the original chip) that are cleaned, refilled with high-quality ink and print-tested, so they fit and communicate like the original at a fraction of the price. Compatible cartridges are built new by a third party with their own chip. Castle Ink sells remanufactured inkjet cartridges and compatible (newly manufactured) toner.

Frequently Asked Questions

What is in this pack?

HP 56 Black (C6656AN); HP 57 Tri-Color (C6657AN).

Can I buy single cartridges later?

Yes. Replace each cartridge as it runs out; you do not need to replace them all at once.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original supply directly caused damage, that specific repair might not be covered.

How long can I store it?

Store it sealed, at room temperature and out of direct sunlight, and use it within about 24 months for best results. Once opened, install it promptly.

When will my order ship?

Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
