Chips, Printer Messages & Installation

Installing: with the printer on, open the ink access door and wait for the carriage to stop. Press the front of the old cartridge to release it, unwrap the new one and push it into the slot with the matching color until it clicks. Close the door and let the printer finish its startup routine before printing.

Chip: this version carries a new aftermarket chip. If the printer reports a cartridge problem, remove it, check the contacts are clean and reseat it; if HP firmware has been updated, the OEM-chip version is the safer pick.

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 that are cleaned, refilled with high-quality ink and print-tested, so they fit like the original at a fraction of the price. Compatible cartridges are built new by a third party with their own chip. This version carries a new aftermarket chip in place of the original. Castle Ink sells remanufactured inkjet cartridges and compatible (newly manufactured) toner.

Other Options for the Same Printers

• Same cartridge with the original HP chip (T6M18AN – OEM Chip)
• HP 902XL Black (T6M14AN) – OEM Chip
• HP 902XL Cyan (T6M02AN) – OEM Chip
• HP 902XL Magenta (T6M06AN) – OEM Chip
• HP 902XL Yellow (T6M10AN) – OEM Chip

Frequently Asked Questions

What is the difference between HP 906XL and 902XL black?

Both fit the same slot. The 906XL holds more ink and is rated at about 1,500 pages, versus about 825 for the 902XL black.

Does HP 906XL work with the HP 902XL colors?

Yes. Use the 906XL black with HP 902 or 902XL cyan, magenta and yellow.

OEM chip or new chip: which should I choose?

The OEM-chip version reuses the original HP chip and is the most dependable on OfficeJet Pro 6900-series printers with recent firmware. The new-chip version works on most printers; if it is rejected after a firmware update, switch to the OEM-chip version.

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.
