Epson EcoTank ET-4903 Ink Replacement Guide

  1. Turn on the printer and check the ink levels through the tank windows or on the screen.
  2. Open the scanner unit or ink compartment cover, then open the cap of the tank you want to refill.
  3. Slowly remove the cap from the compatible CompAndSave Epson 4903 ink bottle, keeping it upright.
  4. Match the bottle color to the tank label and insert the nozzle straight into the filling port.
  5. Let the ink flow naturally. If it does not start flowing, gently lift and reinsert the bottle. Do not squeeze or shake it.
  6. Once the ink reaches the upper fill line and stops, remove the bottle and tighten its cap. Close the tank cap and printer cover securely.

Epson EcoTank ET-4903 Ink Bottle FAQs

Can Epson EcoTank printer use generic ink?

Absolutely! CompAndSave's generic or compatible ink bottles are designed to meet or exceed the OEM specifications. This means that you can get the same print quality and the same number of prints without paying as much as the original ink bottles. Aside from this, using generic ink bottles will never void the printer's warranty. So you can shop and use our ink bottles without any worry. For more information about our ink bottles and cartridges, check our ink knowledge base, and you will be redirected to the right page.

Are all Epson EcoTank ink the same?

No, they are not. Some Epson EcoTank printers use pigment-type of ink, some use a dye-based type of ink, and others use a combination of both. To know what type of ink your printer uses, you may check the manual that came with it and look for the ink replacement supply. You may also check the existing ink bottles that came with your printer. On the front, there should be a sticker or label with the model number, which is usually a combination of alphanumeric characters. For example, the Epson EcoTank ET-4903 printer uses an ink bottle that has the model code of Epson 522.
