Nine-Pack Black Ink Cartridge Replacement

This nine-pack contains professionally remanufactured black ink cartridges built to replace the HP 21 C9351AN model. Each unit uses dye-based ink and is rated for an approximate yield of 190 pages. The set is designed for home or small-office users who print regularly and want a lower-cost supply of black ink on hand.

Yield and Ink-Type Constraints

The 190-page yield figure follows standard industry measurement methods and will vary with page coverage and print settings. Dye-based ink produces vivid output on plain and photo paper but is less water-resistant than pigment formulas. Buyers should plan reorders around actual print volume rather than the nominal yield alone.

Printer Compatibility Check Required

These cartridges fit a long list of HP DeskJet, OfficeJet, PSC and Fax models including the DeskJet 3910, F300, F335, F4140 and OfficeJet 4315 series. Verify your exact printer model against the supported list before ordering; the cartridges will not work in printers that require a different HP cartridge number.
