LD Products HP 21 Black 3-Pack

This set contains three remanufactured black ink cartridges that replace the HP 21 C9351AN. They are refilled with dye-based ink and tested for print quality. The pack is aimed at owners of compatible HP DeskJet, OfficeJet, Fax and PSC printers who want a lower-cost supply of black ink.

Home users printing everyday documents

Suitable for households and small offices that mainly produce text pages and simple graphics on supported models such as the DeskJet 3910, F300 or OfficeJet 4315. Not suited for buyers who need colour output, higher page yields per cartridge or original HP-manufactured supplies.

Approximate yield 190 pages per cartridge

Each cartridge is rated at roughly 190 pages at standard coverage. This figure determines how often you will need to replace a cartridge and whether the total output of the three-pack matches your print volume.

Questions about this item

Should I buy the 3-pack or a single cartridge for my HP DeskJet 3920?

The 3-pack gives you three HP 21 black cartridges at once, each rated for about 190 pages, so you replace them less often.

What does the 190-page yield mean when I print daily on my OfficeJet 4315?

At roughly five percent coverage, each cartridge prints around 190 pages; dense text or graphics will reduce that number.

Which interface does the HP 21 cartridge use and will it fit my PSC 1410?

The cartridge slots directly into the HP 21 printhead bay used by the PSC 1410 and all other listed DeskJet, OfficeJet and Fax models.
