⚡ At a Glance
- • Ink Yield: 70mL black bottles, designed for extended single-bottle use
- • Best for: Home users and small offices running Epson EcoTank and L-series printers
- • Not ideal for: Printers not listed in the compatibility range or users who require pigment archival ink
Two black T6641 bottles of 70mL each fit a wide list of Epson EcoTank and L-series models. Dye-based formula uses ultrafiltration and quick-dry chemistry to reduce clogging and maintain consistent output.
Fewer Refills - Thanks to 70mL bottle capacity
Each T6641 bottle holds 70mL of black dye ink, stored in a refill-friendly bottle format that reduces the number of tank top-ups needed. Ultrafiltration is used during production to limit particulates and help keep ink paths clear.
Larger bottles mean less frequent attention for busy households or small offices, so printers stay productive for longer stretches between refills.
Cleaner Refills - With a controlled nozzle design
Nozzle-equipped bottles allow more precise pouring into printer tanks, helping to avoid overfilling and spills during the refill process. User feedback highlights the nozzle as helpful for steady flow.
Controlled pouring makes refill jobs quicker and less messy, saving time and reducing waste when topping up ink tanks.
Consistent Output - With a fast-drying, filtered dye formula
Ink is dye-based and processed by ultrafiltration, with a balanced weak acid/alkaline formulation and fast-drying characteristics to lower the risk of nozzle clogging and smudging.
Documents and everyday graphics show solid black tones and reliable drying, suitable for routine office printing and classroom use.
