Epson L6370 Printer

Start Here

IMPORTANT: Before using this product, make sure you read these instructions and the safety instructions in the online User's Guide.

1 Unpack

Note: Do not open the ink bottles until you are ready to fill the ink tanks. The ink bottles are vacuum packed to maintain reliability.

  1. Remove all protective materials from the product.

    Caution: Do not connect to your computer yet.

2 Choose a setup method

The Epson Smart Panel app can help you set up your printer through an interactive, step-by-step process using your smartphone or tablet. After setup, you'll be able to print and scan directly from the app.

Note: If you want to print and scan from your computer, you need to install the product's software. See the "Install software" section on the back of this sheet for instructions.

Option 1: Use your mobile device for setup (recommended)

  1. Download the Epson Smart Panel app from your device's app store. Do not launch the app yet.
  2. Press the power button [power button] until it lights up to turn on the product.
  3. Connect the power cord to the back of the product and to an electrical outlet.
  4. Caution: Do not connect to your computer yet.

  5. Launch the app and follow its instructions to set up your product. If necessary, tap the [+] icon on the top right corner of the app's home screen and select the option to set up a new product.

Option 2: Skip mobile setup

If you do not want to use a mobile device for setup, skip to the "Fill ink tanks" section.

For information on solving problems or reaching Epson support, see the back of this sheet.

3 Fill ink tanks

Warning: Keep the ink bottles out of the reach of children and do not drink the ink.

Caution: 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.

Note: 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 printhead. These bottles will print fewer pages compared with replacement ink bottles. Epson strongly recommends the use of genuine ink to ensure optimal print quality and performance.

  1. Open the ink tank cover, then open the cap for the black (BK) ink tank.

    Note: Refer to the color-coded sticker to identify the color of each tank.

  2. Unpack the black (BK) ink bottle. Hold the ink bottle upright and slowly turn the bottle cap to remove it.

    Caution: 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.

    Caution: Do not touch the flat white cable or the ink tubes and their translucent cover.

    Note: Do not force the bottle into position; each bottle is keyed for each color.

  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 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, store it for later use.

    Note: Do not leave the ink bottle inserted; otherwise the bottle may be damaged or ink may leak.

  6. Securely close the black ink tank cap.
  7. Repeat the previous steps for the other colors.
  8. Close the ink tank cover.
  9. Raise the control panel, then press the power button [power button] to turn on the product. The power light flashes.

    Note: If an error code appears, turn off the product and check that no protective material has been left inside the product.

  10. Select your language.
  11. Note: You can change this setting later using the product's control panel. For more information, see the online User's Guide.

  12. When an Epson Smart Panel setup message appears on the LCD screen, select the option to continue setup from the control panel.
  13. When the message to see the Start Here sheet appears on the LCD screen, press and hold the help button [help button] for 5 seconds.
  14. Follow the on-screen instructions to start ink charging. Ink charging takes about 11 minutes.
  15. Note: When the power light stops flashing, ink charging is complete. Once initial setup of the printer is complete, you can top off the ink tanks with any remaining ink. After some ink is used for charging, the rest is available for printing. See the online User's Guide for instructions.

    Caution: Do not unplug or turn off the product, or raise the scanner unit while the product is charging or you'll waste ink.

  16. Press the OK button [OK button] to proceed with initial setup.

4 Load paper

See the online User's Guide for information about loading capacity, available paper types and sizes, using the ADF, and loading envelopes.

  1. Make sure the product is not charging ink, and then open the front of the paper cassette and pull out the paper cassette until it stops.

  2. Slide the edge guides all the way out.
  3. Insert paper with the glossy or printable side down.

    Note: Make sure the paper is loaded against the front edge guide and not sticking out from the end of the cassette.

  4. Slide the side edge guides against the paper, but not too tightly. Close the front of the paper cassette.

  5. Keep the cassette flat as you insert it all the way.
  6. Select the paper settings on the product's control panel.

Note: You need to load paper before you can adjust the print quality. See "Load paper" on this sheet for details. Select Adjust Later if you want to adjust the print quality later. For more information, see the online User's Guide.

Caution: 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.

  • If you see a firewall alert message, click Unblock or Allow to let setup continue.
  • If your network has security enabled, make sure you enter your network password (WEP key or WPA passphrase) correctly. Be sure to enter your password in the correct case.

There are lines or incorrect colors in my printouts.

Run a nozzle check to see if there are any gaps in the printout. Then clean the printhead, if necessary. See the online User's Guide for more information.

The product's screen is dark.

Make sure your product is turned on and press any button to wake it from sleep mode.

Setup is unable to find my product after connecting it with a USB cable.
