Pro Tip
Always keep an extra 950XL (CN045AA) black cartridge in reserve; office inkjets perform periodic self-maintenance cycles using small amounts of ink across all cartridges, but document-heavy tasks will deplete black ink long before cyan, magenta, or yellow.
Frequently Asked Questions
Can I install a 950XL cartridge if my printer originally came with a standard HP 950 cartridge?
Yes. The 950XL (CN045AA) cartridge has the exact same external physical dimensions as the standard 950 cartridge and fits into the exact same slot, but contains a larger internal ink reservoir for higher page yields.
Why does my HP OfficeJet Pro 8100 stop printing when only one colour cartridge is empty?
HP OfficeJet Pro printers require active ink in all four channels (black, cyan, magenta, yellow) to cool and protect the thermal printhead. Replacing the depleted 951XL (CN046AA, CN047AA, or CN048AA) cartridge restores full printing functionality.
How do high-yield 951XL colour cartridges handle uneven colour depletion in office documents?
Office documents often feature logos or headlines in specific colours, causing individual cartridges like 951XL Cyan (CN046AA) or Yellow (CN048AA) to empty faster. Because this system uses individual colour cartridges, you only need to replace the specific colour that has run dry.
