Frequently Asked Questions
Can I install HP 96 and 97 cartridges if my printer currently has HP 94 and 95 fitted?
Yes. HP 96 (C8767WA) black and HP 97 (C9363WA) tri-colour cartridges share the exact physical dimensions and contact pin structure as standard 94 and 95 cartridges, sliding straight into the exact same carriage slots.
What happens when one colour depletes in the tri-colour cartridge?
Because HP 95 (C8766WA) and 97 (C9363WA) cartridges combine cyan, magenta, and yellow ink within a single housing, the entire cartridge must be replaced once any single colour runs out to preserve true-to-life colour accuracy.
Are compatible HP 94 and 95 ink cartridges safe for routine home office printing?
Yes, ISO-certified compatible cartridges are engineered to match factory specifications for print quality and page capacity, providing a cost-effective alternative backed by our money-back guarantee.
