HP 303XL Original Ink Cartridge · High Yield Black · approx. 600 Pages · 12 ml · for ENVY Photo & ENVY Inspire

HP HP 303XL (T6N04AE) is a genuine HP high yield ink cartridge in black, 12 ml, rated at approx. 600 pages, made for owners of HP ENVY Photo, ENVY Inspire and Tango printers who want the manufacturer's own ink rather than a compatible.

ENVY Photo and ENVY Inspire printers use a hybrid ink system — pigment black for text, dye colour for photos — and this is the high-capacity black half of it.

Original HP cartridges are recognised by the printer and the HP Smart app, so ink levels are reported correctly and you avoid the "non-HP cartridge" warnings — and the firmware updates HP printers receive can stop cartridges with cloned chips from working, which does not affect originals.

• 1 × HP 303XL high yield black ink cartridge (T6N04AE)
• Protective tape over the nozzles — remove before installing
• Tri-colour cartridge not included (HP 303XL tri-colour, T6N03AE)

• The yield is HP's figure measured with the ISO/IEC 24711 or HP testing methodology method on a standard mixed text-and-graphics test page. Full-page colour, photos or heavy graphics use ink faster, so real page counts will be lower; plain text documents usually land close to the rating.
• 12 ml of pigment black — text stays crisp on plain paper, which matters for homework, forms and letters printed on a photo-focused printer.
• XL and standard 303 fit the same slot; the XL is the better buy if you print text every week.
• The printhead is built into the cartridge, so every new cartridge also brings fresh nozzles. If prints are streaky and cleaning cycles do not help, a new cartridge usually fixes it.
• Installing takes a minute: open the cartridge access door, wait for the carriage to stop, press down on the old cartridge to release it, pull the pink or orange tape off the new cartridge without touching the copper contacts or nozzles, and slide it in until it clicks.
• Keep spare cartridges sealed in their box at room temperature and install them before the date printed on the packaging; an opened cartridge is best used rather than stored.
• Empty HP cartridges can be returned for free recycling through HP Planet Partners where the programme is offered.
• HP sells its consumer and office ink cartridges by region. This is the European/EMEA version, made for printers sold in Europe, the Middle East and Africa — which covers printers bought in Cyprus, Greece or elsewhere in the EU.

• HP 302, 304 or 305 printers — the numbers are close but the cartridges are not interchangeable.
• Colour printing — black cartridge only.
• A printer bought in the US, Latin America or Asia — it is set up for that region's cartridges and can reject this European version.
• Any printer that is not in the compatibility list below — if your model is not listed, send us the model before ordering.
