Chips, Printer Messages & Installation

Installing: with the printer on, open the ink access door and wait for the carriage to stop. Remove the empty cartridge, unwrap the new one, pull off any protective tape without touching the copper contacts, and push it into the matching slot until it clicks. Close the door and let the printer finish its startup routine.

Ink level messages: the printer may show a "used" or "non-HP" cartridge notice, or an ink gauge that reads low or "?". Press OK to continue and judge by print quality, not the gauge.

Firmware updates: HP firmware updates have been known to block non-HP chips. Turn off automatic updates in the printer's settings or HP Smart before you install, and see how to keep HP firmware updates from blocking your ink.

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 use HP 952XL black instead?

Yes. HP 952XL black (F6U19AN) fits the same slot. The 952XL color cartridges work with either black.

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.

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.
