Frequently Asked Questions

• How many pages does the HP C2P23AN print?

  HP rates the C2P23AN at about 1,000 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 color pages use far more ink than plain text.

• Which printers take the C2P23AN?

  It fits OfficeJet 6812, OfficeJet 6815, OfficeJet Pro 6220, OfficeJet Pro 6230 and 3 more. The complete verified list is in the Compatible Printers section on this page — check your model there before ordering.

• Which number is the black — 934 or 935?

  In this family the black is the HP 934 and the three colors are HP 935. The two numbers are one system — a printer that takes one takes the other.

• Standard or XL — which should I buy?

  This is the high-yield version, rated at about 1,000 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 C2P23AN pigment or dye ink?

  It is pigment ink — the same ink technology HP uses in the original C2P23AN — so text stays sharp and resists water and highlighter smear.

• What chip does this cartridge use?

  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.

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

  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.

• Will it work next to genuine HP cartridges in the other slots?

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

• What does the AN at the end of the code mean?

  It is HP's regional suffix: AN codes are the North American version. These printers are region-matched, so a cartridge coded for another region is rejected even though it looks identical — every cartridge here is the AN version.

• Is this made by HP?

  No. It is a Clever Supplies compatible cartridge built to the C2P23AN 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 cover do I have if this cartridge fails?

  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 colors too?

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