Four-cartridge black set

This pack contains four remanufactured black ink cartridges that replace HP 45 and 51645A models. They are built for owners of compatible PhotoSmart, OfficeJet, DesignJet, DeskJet, Color Copier and Fax printers who want a ready supply of black ink.

Dye-based ink with 1100-page yield

Each cartridge uses dye-based ink rated at approximately 1100 pages, giving enough headroom for regular document and photo printing. Heavy graphics or dense coverage will reduce the actual page count before replacement is needed.

Direct fit for listed HP printers

The cartridges install directly into the printer models named in the compatibility list, requiring no adapters or firmware steps. Using this four-pack frees you from frequent single-cartridge orders and keeps a spare on hand for uninterrupted output.

Questions about this item

Will these 51645 cartridges work in my older DeskJet 895Cxi without firmware issues?

The 51645 cartridges are listed as compatible with the DeskJet 895Cxi among many DeskJet and OfficeJet models, so they should install and print normally in that printer.

How can I confirm the cartridges are printing correctly after I install them in my PhotoSmart 1115?

Run a test page or alignment page from the PhotoSmart 1115 control panel; the dye-based black ink should produce sharp text and consistent density across the page.

Does the 4-pack include only the four black cartridges, or are printheads or cleaning kits also inside?

The package contains four remanufactured high-yield black ink cartridges (model 51645) and nothing else; printheads or maintenance kits must be purchased separately if needed.
