Home Support Projectors Pro Series Epson Pro L20000U

I installed an optional lens and now the lights on my projector indicate a lens shift error. What should I do?

    When the projector is in this state, you will need to press and hold the Lens Shift button on the remote controller until the lens starts to move. Then, release the button, wait for the lens to stop moving, and power cycle the projector.

    If the error continues, you will need to remove, reattach, and calibrate the lens to correct the lens shift error. See the instructions below.

    Removing a Lens

    You can remove a lens to replace it with a different lens.

    Warning: Turn off the projector and unplug its power cord before attaching or removing a lens; otherwise you could receive an electric shock.

    Caution:
    Remove the lens only when necessary and make sure the front of the projector is not facing up when you remove the lens. This prevents dirt or dust from entering the projector and lowering the projection quality. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.

    1. Center the lens using the Lens Shift button.
    2. Turn off the projector and unplug the power cord.

      Warning: Wait about 30 minutes after turning off the projector before removing the lens. Touching the lens immediately after projecting or turning off the projector may cause burns.

    3. Use your hand to loosen the screw securing the lens cover to the projector.

    4. Press the buttons on the sides of the lens cover and pull the lens cover off the projector.
    5. Hold the lens firmly as you release the lens lock. Pull the black lever up (1), pinch the metal tab against the lever, move it toward the Release position until it stops (2), and then push the black lever in as shown (3).



    6. Remove the lens from the projector.
    7. If you are not attaching a different lens right away, replace the lens cover and lens cover cap to protect the projector.

    Attaching a Lens

    You can attach a compatible lens to the projector.

    Warning: Turn off the projector and unplug its power cord before attaching or removing a lens; otherwise you could receive an electric shock.

    1. Turn off the projector and unplug the power cord.

      Caution:
      Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface. Make sure the front of the projector is not facing up when you attach the lens. This prevents dirt or dust from entering the projector and lowering the projection quality.

    2. Use your hand to loosen the screw securing the lens cover to the projector.

    3. Press the buttons on the sides of the lens cover and pull the lens cover off the projector.
    4. If you are attaching the ELPLX02 or ELPLX02W lens, loosen the screws securing the lens replacement cover on top of the projector and slide the cover off as shown.

    5. If the lens lock lever is in the Lock position, release the lock lever. Pull the black lever up (1), pinch the metal tab against the lever, move it toward the Release position until it stops (2), and then push the black lever in as shown (3).



    6. If the lens has a cap covering its narrower end, remove the cap and store it for use if you remove the lens later.
    7. Position the lens so the white circle is on top and insert the lens straight into the projector's lens socket.

    8. Hold the lens firmly as you lock the lens in place. Pull the black lever up (1), pinch the metal tab against the lever, move it toward the Lock position until it stops (2), and then push the black lever in as shown (3).



    9. Replace the lens cover as shown.

    10. Tighten the screw to secure the lens cover to the projector.

    11. Do one of the following:
      • If you attach a lens that is different from the previous lens, you see a message to calibrate the lens the next time you turn on the projector. Select Yes to calibrate the lens.
      • If you remove and attach the same lens, press and hold the Default button on the remote control for at least 3 seconds or select Lens Calibration in the Extended menu to calibrate the lens.
      Lens calibration takes up to 3 minutes to complete. When calibration is finished, the lens returns to its previous position.

      Caution:
      If you see a message that lens calibration failed, turn off the projector, unplug the power cord, remove the lens, and reinstall it. If you continue to see an error message, contact Epson.
