Frequently Asked Questions

Will the T636400 ink cartridge void my Epson printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, Epson cannot void your printer warranty solely because you installed a compatible (non-OEM) ink cartridge. The T636400 is designed to drop in as a direct replacement for the OEM part.

How does print quality compare to the genuine Epson T636400?
The T636400 is engineered to match the OEM cartridge's ink chemistry and head-firing characteristics, so day-to-day output should look essentially identical to the original Epson T636400. If you ever see a difference, our 100% satisfaction guarantee covers a free replacement or refund.

Which printers use the T636400?
The T636400 fits a range of Epson models (Epson Stylus series), including the Stylus Pro 7700, Stylus Pro 7890, Stylus Pro 7900. The full compatibility list is in the Compatible Printers section above - check your printer model there before ordering.
