Chips, Printer Messages & Installation

Installing: open the ink cartridge cover, lift out the empty cartridge and gently shake the new one before pushing it into the matching color slot until it seats. Close the cover and wait for the printer to finish checking the ink.

Non-HP supply messages: DesignJet printers display a notice when a refilled or non-HP cartridge is installed. Confirm the message on the front panel to keep printing. If a cartridge is not detected, reseat it and check the chip contacts are clean.

Printheads are separate: DesignJet printheads are replaced on their own schedule, not with each ink cartridge. If a color is missing after a new cartridge, run the printhead cleaning from the front panel.

Still stuck? See our guide to fixing a cartridge that isn't recognized or contact us and we'll make it right.

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

Can I replace one color at a time?

Yes. Each color is a separate cartridge, so replace only the one that is empty.

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.
