Epson Types 126 and 127 ink jet cartridges are used in several Epson WorkForce® ink jet printers and All-in-Ones (ink jet multifunction printers). Each printer uses four ink cartridges (cyan, magenta, yellow and black), which are available in high-capacity and extra high-capacity yield versions.
Ink cartridge SKUs differ by geographic region and each cartridge requires a chip for correct printer operation.
