Chips, Printer Messages & Installation

Installing: open the ink cartridge drawer or door for the color you are replacing, lift out the empty cartridge and gently shake the new one before sliding it into the matching slot until it seats. Close the door; the printer checks the cartridge and updates the ink level.

Non-HP supply messages: PageWide XL printers show 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 make sure the chip contacts are clean.

Printheads are separate: PageWide XL printheads stay in the printer and are replaced on their own schedule. If a color looks weak after a new cartridge, run the printhead check and cleaning from the front panel.

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.

Does it include a printhead?

No. PageWide XL printheads stay in the printer and are replaced separately.

Why is it sold by volume instead of pages?

Wide-format inks are rated in milliliters because coverage on large drawings and posters varies so much.

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.
