These cartridges are extremely easy to refill, simply remove the plug and syringe in the ink. It is essential that you use an ink specifically formulated for use in the Epson 3800, such as our 100ml or 250ml resin encapsulated Premium Platinum Photo Pro Pigment inks (available here) and install as per genuine Epson cartridges.
