This Epson 407 black ink cartridge is compatible only with a select few WorkForce Pro inkjet printers, but owners of those machines are sure to love this cartridge. Not only does the Epson C13T07U140 offer the best quality prints that your printer can produce, but it last a long while too.Surprisingly large for an inkjet cartridge, the genuine Epson 407 black offers an estimated 2,600 prints from each cartridge. The high amount of ink within the Epson C13T07U140 means more pages and further reduces the running costs of your printer, if original cartridges are a necessity for you.
