What's in the Box
- 1 × HP 950XL Black (CN045AN) — about 2,300 pages
Page yields are the manufacturer's ISO/IEC 24711 ratings for the matching original cartridge, measured at roughly 5% page coverage. Your results will vary with what you print.
Note: HP's specification table rates the 950XL black at about 2,300 pages (ISO/IEC 24711); some newer HP and retailer listings quote up to 1,650 pages.
HP 950 / 951 Standard vs. High-Yield: Which Should You Buy?
| Version | Part numbers | Black yield | Color yield |
|---|---|---|---|
| Standard | 950 black CN049AN; 951 C/M/Y CN050AN/CN051AN/CN052AN | 1,000 | 700 |
| XL | 950XL black CN045AN; 951XL C/M/Y CN046AN/CN047AN/CN048AN | 2,300 | 1,500 |
All versions fit the same printers. Higher-yield cartridges cost more up front but less per page, so they make sense if you print regularly.

Chips, Printer Messages & Installation
Firmware note: in September 2016 an HP firmware update made some OfficeJet Pro 8600/8610/8620/8630-series printers reject non-HP cartridges, and HP then released an optional update that restored support. These cartridges keep their original HP chip. If your printer shows a cartridge error, contact us and we'll help.
Dynamic security: HP firmware can block cartridges that use a non-HP chip. These are remanufactured from genuine HP cartridges and keep the original HP chip rather than a third-party one. If you see a "cartridge problem" or "used cartridge" message, select OK or Continue; if a cartridge isn't recognized, remove it, check that the protective tape is off, wipe the copper contacts and reinstall.
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. Castle Ink sells remanufactured inkjet cartridges and compatible (newly manufactured) toner.
