Our recycling partners who produced the remanufactured T6367 used some of the highest quality dye based light black ink when refilling these Epson units, the result being prints that can be proudly displayed. If held alongside pages produced by genuine Epson C13T636700 cartridges, the results will be comparable, but sadly do not offer the extended long-life protection of original light black ink. This remanufactured Epson cartridge retains many components from the original T6367, but when necessary parts have been replaced with top-quality compatible parts. Our remanufactured Epson C13T636700 still offer compatibility with all the same incredible printers, and the keeps the 700ml capacity that you have come to love as well.
