Fill ink tanks

Keep the ink bottles out of the reach of children and do not drink the ink.
This product requires careful handling of ink. If ink spills, wipe it off immediately with a damp towel to avoid permanent stains. If ink gets on your clothes or belongings, it may not come off.  After setup, periodically inspect the ink levels to ensure they do not fall below the lowest lines on the tanks. Prolonged use, when ink is below the lowest line, could damage the product. See the online User’s Guide for refilling instructions.


  • Epson cannot guarantee the quality or reliability of third-party ink.
  •  Use the ink bottles included with the printer to set up the product. Part of the ink will be used to charge the print head. These bottles may print fewer pages compared with replacement ink bottles.
  • Epson strongly recommends the use of genuine ink to ensure optimal print quality and performance.


  1. With the scanner unit raised, open the ink tank cover, then open the cap for the black (BK) ink tank.

    Epson ET-3843 All-in-one printer fig 2Caution: Do not shake or squeeze the ink bottle. Do not touch the top of the ink bottle after its cap is removed.
  3. Insert the ink bottle into the filling port.

  4. Wait for the ink to fill the tank. Do not squeeze the bottle or allow it to contact any other surface.

    Note: Ink flows into the tank and stops automatically when the ink tank is filled to the upper line. If the ink does not flow from the bottle, lift and reinsert the bottle.
  5. When the ink tank is full, remove the ink bottle and securely close it with the bottle cap. If any ink remains in the bottle, close the bottle and store it for later use.
