High Page Yield – thanks to 70mL bottles
Each black bottle is 70mL and each colour bottle is 70mL, with stated yields up to 4,000 pages for black and up to 6,500 pages for colour at 5% coverage. Those figures assume typical low-coverage documents rather than heavy photographic prints.
Fewer bottle changes during long print runs, so less downtime and reduced ongoing supply handling for heavy users.
Consistent Colour and Text – with ultrafiltration and fast-drying dye ink
Ultrafiltration is used to remove particulates and the dye-based formula is described as fast-drying and balanced to avoid strong acidity or alkalinity. The combination is intended to keep nozzles clear and inks stable on paper.
Sharp documents and dependable colour reproduction with fewer maintenance interruptions and lower risk of clogging.
Wide Printer Compatibility – thanks to extensive Epson model support
Compatibility is listed for many Epson EcoTank and L-series models, including ET-2500, ET-2550, ET-2600, ET-2650, ET-3600, ET-4500, ET-4550, L355 and L555 among others. Multipack coding uses T664-series references for matching bottles.
