V4ink 522 Ink Cartridge 4 Colour 70ml Kit

Kit contents

This kit contains four 70 ml bottles covering black, cyan, magenta and yellow ink. It is designed for owners of EcoTank ET-2720, ET-2800, ET-4800 and ET-2803 printers who need a complete colour set. The aftermarket formulation is not sublimation ink and suits everyday document and photo printing in home or office environments. Buyers whose printers use a different cartridge number cannot use this kit.

Filling workflow

Each bottle fits directly into the matching EcoTank reservoir without extra tools or syringes. The refill process frees you from disposable cartridge waste and lets you top up tanks at any time. No chip reset or printer firmware step is required beyond the normal ink-level calibration. Printers that lack front-access tanks or use a different bottle key will not accept these bottles.

Sustained use

The ink is formulated to maintain consistent colour density and flow during long print runs without clogging the printhead. Regular refilling keeps the cost per page low compared with single-use cartridges. Office users printing high volumes daily will see stable output quality over weeks of continuous operation. Environments that demand archival-grade lightfastness or specialised media coatings are not addressed by this general-purpose ink.
