Frequently Asked Questions

• How many pages does the HP C4909AN print?

  HP rates the C4909AN at about 1,400 pages under ISO/IEC 24711 test conditions, printing standard pages at around 5% coverage. Your own count will move with coverage, paper and settings — dense colour pages use far more ink than plain text.

• Which printers take the C4909AN?

  It fits OfficeJet Pro 8000, OfficeJet Pro 8000 Wireless, OfficeJet Pro 8000 Enterprise, OfficeJet Pro 8500 and 5 more. The complete verified list is in the Compatible Printers section on this page — check your model there before ordering.

• Which printers still use HP 940?

  The OfficeJet Pro 8000 and OfficeJet Pro 8500 generations — business printers built with separate ink tanks and printheads in the printer. The family is discontinued by HP, which is exactly why a compatible supply matters for machines still in daily service.

• Standard or XL — which should I buy?

  This is the high-yield version, rated at about 1,400 pages. It costs more up front than the standard cartridge and far less per printed page, so it is the right pick for regular printing; the standard size suits a printer that only runs occasionally.

• Is the C4909AN pigment or dye ink?

  It is pigment ink — the same ink technology HP uses in the original C4909AN — so text stays sharp and resists water and highlighter smear.

• Is there a chip on this cartridge?

  Yes — a new compatible chip that reports ink levels to the printer, so the low-ink warnings keep working. It is not a refilled original shell with a reset chip.

• The printer is showing a warning after I installed it — what now?

  Acknowledge the on-screen message, reseat the cartridge until it clicks, and restart the printer. If the warning persists, wipe the gold chip contacts with a dry lint-free cloth and reinstall.

• Can I run this alongside original HP cartridges?

  Yes. Each slot is read independently, so a compatible black alongside original colours (or the other way round) prints normally.

• Is the printhead included?

  No — on this family the printheads (940 printheads) live in the printer. These are ink tanks only, which is why they carry more ink per cartridge.

• Is this a genuine HP cartridge?

  No. It is a Clever Supplies compatible cartridge built to the C4909AN specification and covered by our lifetime warranty. It is not manufactured by HP; the HP name appears only to identify the printers it fits.

• What happens if it leaks or the printer will not recognise it?

  Stop and contact us — do not keep printing on a faulty cartridge. The lifetime warranty covers recognition failures, leaks and print-quality defects: we replace the cartridge or refund you.

• Need the other colours too?

  The full set and the other single colours are linked under the family list on this page, so you can match this cartridge with its matching set.
