What you get: LD Products HP 21 black ink 5-pack

This pack contains five remanufactured black ink cartridges that replace the HP 21 (C9351AN). Each cartridge is filled with dye-based ink and rated for approximately 190 pages. The cartridges are cleaned, refilled and print-tested before packaging. Condition is new.

Who this suits and who should look elsewhere

Home users and small offices with compatible HP DeskJet, OfficeJet, PSC or Fax models listed in the specifications will find a direct replacement. Buyers who need colour output, higher page yields per cartridge or original HP-manufactured supplies should consider other options.

Deciding specification: 190-page yield per cartridge

The approximate yield of 190 pages per cartridge is the single figure that determines whether this pack matches your typical print volume. Check your average monthly pages against that number to decide if the 5-pack quantity is right for you.

Questions about this item

How do I install these cartridges and avoid the common mistake?

Remove the protective tape from the print-head nozzles before inserting each cartridge into the carriage; the step most often missed is forgetting to peel that tape off completely.

What maintenance will these cartridges need later?

No routine maintenance is required; when print quality fades after roughly 190 pages per cartridge, replace the empty unit with a new one from the pack.

What limit appears first during heavy printing sessions?

The page yield of about 190 pages per cartridge is the first constraint you will reach under sustained use.
