Frequently Asked Questions

• How many pages does the HP 4S6V6LN print?

  HP rates the 4S6V6LN at about 2,500 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 4S6V6LN?

  It fits OfficeJet Pro 9110b, OfficeJet Pro 9125, OfficeJet Pro 9135, OfficeJet Pro 9720 and 1 more. The complete verified list is in the Compatible Printers section on this page — check your model there before ordering.

• Is the 936 the same as the 923e?

  No. Both are EvoMore-generation cartridges, but they serve different printer series and are not interchangeable — match the number on your old cartridge.

• Is the 4S6V6LN pigment or dye ink?

  It is pigment ink — the same ink technology HP uses in the original 4S6V6LN — 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. 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.

• 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.

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

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

• My 9720/9730 shows a setup-cartridge message — what does that mean?

  Wide-format OfficeJet Pro models can ask for the setup cartridges that shipped in the printer box for first-time initialisation. A printer that has completed setup takes these cartridges normally.

• Is this made by HP?

  No. It is a Clever Supplies compatible cartridge built to the 4S6V6LN 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 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.
