How to Fill Epson Stylus Cx3900 Ink Cartridges

By Marques Williams

  • Overview

    Refilling an Epson CX3900 ink cartridge is less expensive than buying a new cartridge. Not only that, but the cartridge is easier to refill than other models, thanks to its auto-reset chip.
    • Step 1

      Place the cartridge on a table and remove the fill plug from it.
    • Step 2

      Slowly and carefully fill the ink cartridge with the appropriate color ink. Be careful not to overfill.

    • Step 3

      Attach the bottom fill adapter to the syringe and remove 1 cc of ink through the exit port seal at the bottom of the cartridge.
    • Step 4

      Put the fill plug back in its original place in the cartridge and remove the vent plug, which will be next to it.
    • Step 5

      Place the cartridge back into the printer.
