  The box holds: 3HZ99AN (1,000 pages), 3HZ96AN (700 pages), 3HZ97AN (700 pages), 3HZ98AN (700 pages). Each cartridge is individually sealed.

• Which printers does this set fit?

  The set fits OfficeJet 9012, OfficeJet Pro 9010, OfficeJet Pro 9015, OfficeJet Pro 9016 and 5 more. The complete verified list is in the Compatible Printers section on this page.

• What is the HP 966XL?

  An extra-high-yield black (about 3,000 pages) that only the OfficeJet Pro 9020 series takes. If your printer is a 9020-series model, the 966XL black is the lowest cost per page in this family; the 962XL black serves the other 962 models.

• Are all the cartridges in this set chipped?

  Yes. Every cartridge in the set carries a new compatible chip that reports its own ink level to the printer.

• Set or singles — which is better value?

  Yes — the set is priced below the same cartridges bought one by one, and one box restocks every slot at once. Check the per-cartridge yields above against your usage.

• Will this work if my printer uses HP+?

  if your printer was set up with HP+, it accepts original HP cartridges only — that lock is part of the HP+ program and applies to every non-original cartridge, ours included. On printers that are not HP+-locked, these cartridges install and print as normal.

• Can I fit one cartridge now and keep the rest sealed?

  Yes. Open and install only the colour the printer asks for, and keep the rest sealed — they store fine for when their turn comes.

• A warning appeared after fitting this cartridge — how do I clear it?

  Acknowledge the message, reseat the cartridge until it clicks and restart the printer. Most warnings are a one-time notice that a non-original cartridge was fitted. The 962 family carries HP's strictest dynamic-security regime: the printer verifies the chip on every cartridge, and HP+ enrolled units accept original HP cartridges only. Our cartridges use a new compatible chip matched to these models; keep the printer's firmware as-is where you can, and if an update ever blocks a cartridge, the lifetime warranty covers you.

• Why does HP warn about non-original cartridges on these printers?

  The 9020 series runs HP's strictest firmware checks plus optional HP+ enrolment. Our cartridges use new compatible chips matched to these models, and the lifetime warranty covers you if an HP update ever changes recognition.

• Is this set made by HP?

  No. It is a Clever Supplies compatible set built to the original HP specifications and covered by our lifetime warranty. It is not manufactured by HP.

• Am I covered if just one cartridge in the box is bad?

  Contact us with the colour and the problem — the lifetime warranty covers each cartridge in the set individually, so a single faulty cartridge is replaced on its own.

• Which cartridge in the set runs out first?

  It depends on what you print: text-heavy use drains the black first, photo and graphics work drains the colours. Each cartridge reports its own level, and the spares from this set store sealed until their slot asks for them.
