The Epson T40C340 is a magenta ink cartridge from the UltraChrome XD2 line, designed specifically for professional inkjet plotters. This cartridge with a 26ml capacity ensures that your technical drawings and posters maintain sharp detail and resist fading over time. It is compatible with several SureColor models, including the SC-T2100, SC-T3100 series, and SC-T5100 series. Because it contains 1,2-benzisothiazol-3(2H)-one, you should be aware that it may cause an allergic reaction in some users.
