The Epson UltraChrome XD2 T40 is a magenta pigment-based ink cartridge designed for professional technical printing. With a 50ml capacity, this ink provides the consistency and durability needed for high-quality drafts and detailed plans, making it a reliable choice for those using SureColor SC-T2100, SC-T3100 (including M-MFP and N versions), and SC-T5100 (including M and N versions) printers. It is also compatible with Sharp LUNA 1.5 MX-B427PWEU and MX-B427WEU models. Because it uses pigment ink, your magenta prints will be more resistant to smudging and fading over time compared to standard dyes. This makes the 50ml cartridge particularly useful for architects and engineers who need their documents to remain legible in demanding environments. While a single color cartridge can support up to 30,000 pages, the set is built to handle heavy workloads without frequent replacements.
