How to Replace Cartridge(s)

Refilling the ink tank in your Epson WorkForce ET-4550 printer with a new ink bottle is easy. Here's how you do it:

  1. Wear disposable gloves so you don't stain your hands. Place a sheet of paper under the ink tank.
  2. Turn on the printer, then open the ink tank cover.
  3. Remove the ink tank cap, then place it in the holder.
  4. Snap off the tip of the ink bottle, remove the bottle cap, and then carefully peel off the protective seal. Tightly close the bottle cap.
  5. Refill the ink tank with the appropriate color ink up to the upper line of the tank.
  6. If there's ink remaining in the bottle, place the bottle cap tip securely on the cap. Make sure to store the ink bottle upright for later use.
  7. Replace the ink tank cap and close the ink tank cover.
