Frequently Asked Questions

• How many pages does the HP L0R39AN print?

  HP rates the L0R39AN at about 3,000 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 colour pages use far more ink than plain text.

• Which printers take the L0R39AN?

  It fits OfficeJet Pro 7740, OfficeJet Pro 8216, OfficeJet Pro 8720, OfficeJet Pro 8725 and 2 more. The complete verified list is in the Compatible Printers section on this page — check your model there before ordering.

• Which printers take the 956XL?

  Only six wide-format and high-end models: the OfficeJet Pro 7740, 8216, 8720, 8725, 8730 and 8740. Other 952 printers have no 956XL slot rating — for them the 952XL black is the top yield.

• Standard or XL — which should I buy?

  This is the high-yield version, rated at about 3,000 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 L0R39AN pigment or dye ink?

  It is pigment ink — the same ink technology HP uses in the original L0R39AN — 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. This family runs HP dynamic security: the printer checks the cartridge chip, and HP firmware updates can change what is accepted. Our cartridges carry a new compatible chip built for these models; if a future HP firmware update ever blocks a cartridge, the lifetime warranty covers you — contact us and we will put it right.

• 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.

• Which yield figures are the right ones for 952?

  HP's own printer pages and cartridge pages once differed; the cartridge product data — 952 at about 900/630 pages and 952XL at about 2,000/1,450 — is the set we use, and the set printed on our boxes.

• Is this a genuine HP cartridge?

  No. It is a Clever Supplies compatible cartridge built to the L0R39AN 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.
