freecolor Remanufactured Ink Cartridge for HP 903XL Black, 30 ml, 850 Pages, for OfficeJet 6950 and OfficeJet Pro 6960/6970

The freecolor K20833F7 is a remanufactured ink cartridge that replaces the HP 903XL Black (high capacity), holding 30 ml for 850 pages (per freecolor) — for owners of HP OfficeJet 6950 / OfficeJet Pro 6960–6970 printers who want to cut the cost per page without changing printer.

It is built on a collected original HP shell that is cleaned, tested and refilled by ARMOR Print Solutions. freecolor is the remanufacturing brand of ARMOR Print Solutions (ARMOR Group), sold across Europe for almost 20 years.

• 1 × freecolor remanufactured black ink cartridge, 30 ml (HP 903XL type)
• Colour cartridges are not included — they are separate items

• Cost per page drops: the 30 ml cartridge is rated at 850 pages by the manufacturer, measured per freecolor.
• Installation is the same as with the original: open the cover, take out the empty cartridge, click the new one into the same slot.
• Your printer settings, drivers and paper stay exactly as they are — nothing to install on the computer.
• The OfficeJet Pro 6960/6970 has four separate cartridges, so only the black is replaced when the black runs out.
• Print a nozzle check after installing: if a colour shows gaps, one cleaning cycle from the printer menu usually clears it — avoid running several in a row, as each one uses ink.
• Replace only when the printer reports empty, not at the first low-ink warning — the warning appears while there is still ink left to print with.

• OfficeJet 8010/8020 and OfficeJet Pro 8020/8030 series — they take HP 912/917.
• HP 953/957 printers (OfficeJet Pro 7720/8710 class) — larger cartridge.
• Colour — cyan, magenta and yellow are separate 903-type cartridges.
