The Epson C13T08N140 is the original black ink supply for the Epson WorkForce Enterprise AM-C400 A3 colour multifunction printer. It is rated for about 31,500 pages, so a single unit covers a lot of office printing before it needs replacing and keeps the cost per page down. The AM-C400 is built for high-speed shared office printing, and Epson's own ink is formulated for its printhead, giving crisp black text and reliable, consistent output without the clogging or quality problems that non-genuine ink can cause. The unit is supplied in a sealed Epson box and fits into the printer's front ink bay. Epson notes the ink contains preservatives that may cause an allergic reaction, so follow the label when handling.
