Epson EcoTank ET-4850 Setup Guide – WiFi, Driver & First Print

Category: Setup · Brand: Epson

The Epson EcoTank ET-4850 is a premium all-in-one with refillable ink tanks. Initial setup takes 15–20 minutes, mostly for filling the tanks.

Step 1: Unbox and Fill the Ink Tanks

  1. Remove all packing tape and protective foam from the printer
  2. Lift the scanner unit and locate the four ink tanks on the left side
  3. Open each tank cap and fill using the matching color ink bottle — each bottle is keyed to its color so you can't accidentally fill the wrong tank
  4. Fill each tank to the upper line (do not overfill)
  5. Close all tank caps

Step 2: Initial Ink Charging

  1. Power on the ET-4850 — the printer will begin charging the ink system automatically
  2. This takes approximately 10–15 minutes — do not power off during this process
  3. The printer will print a test pattern to confirm the ink is flowing

Step 3: Connect to WiFi

Using the control panel:

  1. On the touchscreen, tap the network icon or go to Settings > Wi-Fi Setup > Wi-Fi Setup Wizard
  2. Select your Wi-Fi network
  3. Enter your password using the on-screen keyboard
  4. Tap OK — the network icon turns solid when connected

Using WPS:

  1. Tap Settings > Wi-Fi Setup > WPS (Push Button)
  2. Press the WPS button on your router within 2 minutes

Step 4: Install the Driver

  2. Download Epson Connect Printer Setup or the full driver package
  3. Run the installer and select Wireless Connection when prompted

Mac:
