What kind of ink does the Epson 3800 use?
Epson UltraChrome K3 pigment inks. These inks are also used in the Epson Stylus Photo R2400, Epson Stylus Pro 4800, 7800, and 9800 printers. These are not to be confused with the older Epson UltraChrome inks, which are used in the Epson Stylus Photo 2200, Epson Stylus Pro 4000, 7600, and 9600 models. There are nine different inks in the UltraChrome K3 set: Photo Black, Matte Black, Light Black, Light Light Black, Magenta, Light Magenta, Cyan, Light Cyan, and Yellow. The Epson 3800 holds all nine ink cartridges simultaneously.
