Epson T6643 Magenta Ink Bottle 70ml C13T66434A

Epson T6643 Magenta Ink Bottle 70ml C13T66434A: Refill for colour printing

The Epson T6643 Magenta Ink Bottle holds 70 ml of magenta ink, giving owners of compatible Epson EcoTank printers a substantial supply of this colour. Its large bottle capacity and stated yield of approximately 4,000 pages make it a useful replacement for regular printing, rather than a small cartridge intended for only occasional top-ups. Magenta is one of the inks used alongside the other colours, so it contributes to colour prints rather than serving as a standalone black-ink replacement. That makes it relevant for household documents with coloured elements, images and design work where magenta is part of the intended result. Epson describes its inks as reproducing small details sharply, a point that matters on fine lines and compact elements in a printed design. The T6643 is an inkjet ink bottle, identified by the model code C13T66434A; the 70 ml volume is the central detail to compare when replacing your magenta supply. For anyone who prints a mix of text and visuals on a supported EcoTank, this is the matching colour refill to look for. One detail worth keeping in mind: its quoted page capacity is approximate, so the number of pages you get depends on what you print.

Why it is useful

• Magenta ink: This bottle supplies the magenta component used with the printer’s other colour inks. It’s the relevant colour refill for prints that include magenta in an image, design or coloured text.
• 70 ml volume: The bottle contains 70 ml of ink, a notably generous quantity for a replacement colour supply. That volume is useful to know when comparing the T6643 with smaller ink products.
• Approximate yield of 4,000 pages: Epson’s stated capacity gives you a clear indication of the print volume associated with the bottle. Treat the figure as an estimate, particularly if your pages contain large areas of colour.
• Inkjet format: The T6643 is identified as an inkjet ink product. It’s intended for printing through compatible inkjet printers, rather than as toner for a laser printer.
• Sharp small details: Epson’s description notes accurate, sharp reproduction of small details. That’s useful for prints with fine design elements or compact text, where clarity matters.
• For text and visuals: The ink is presented for printing text, images and designs. It therefore covers the kinds of mixed-content pages where coloured elements sit alongside written information.
• Part of a colour set: Magenta works together with the other colour inks for the overall print result. This bottle supplies one colour in that combination, rather than a complete set of inks.

Good to know

The listed compatible printers are the Epson EcoTank ET-2500, ET-2550, ET-4500 and ET-4550. The approximate yield is around 4,000 pages; actual capacity varies with the content being printed, so pages with more colour coverage can use ink differently from simpler text pages. Use the model code C13T66434A to distinguish this magenta bottle when selecting a replacement.
