HP 303 Black Original Ink Cartridge — ~200 pages, 4 ml, for HP ENVY Photo 7800 series & HP Tango X

HP T6N02AE is the HP 303 Black Original Ink Cartridge, rated at ~200 pages (ISO/IEC 24711 or HP testing methodology) — for home and small-office users who want the printer to run as HP designed it.

It handles the black channel only; colour comes from the HP 303 Tri-color cartridge.

• 1 x HP 303 Black Original Ink Cartridge (T6N02AE) in HP retail packaging
• Cartridge only — other colours and printer accessories are sold separately

• ~200 pages is the HP rated average (ISO/IEC 24711 or HP testing methodology, tested in HP ENVY 7800 All-in-One). Pages with photos, large colour areas or frequent single-page jobs use more ink, so real-world yield varies.
• 4 ml of pigment-based ink — pigment ink gives sharp, smudge-resistant prints on plain paper.
• Installation: open the cartridge door, wait for the carriage to stop, unclip the old cartridge, remove the protective tape from the new one and click it in. The printer may run a short alignment.
• Genuine HP supply: the printer recognises it and does not show non-original supply warnings.

• Printers not listed here that use a different cartridge number — HP 302 and HP 304 cartridges look similar but are different numbers and will not fit HP 303 printers.
• It does not print colour — colour needs the HP 303 Tri-color cartridge.
