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

• When the Status light is flashing blue and the Laser and Temp lights are orange, your projector is indicating a lens shift error. 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.

  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.
  3. Press the tabs on both sides of the lens cover and pull the lens cover off the projector.
     
  4. Hold the lens unit firmly as you slide the lock lever to the left.
     
     

     Caution:
     Avoid touching the areas shown here or you may damage the lens unit.

  5. Gently pull the lens straight out of the projector.
     

  Attaching a Lens

  You can attach a compatible lens to the projector.
  1. Turn off the projector and unplug the power cord.

     Caution:
     Unplug the power cord from the projector before attaching the lens. Avoid touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.

  2. Press the tabs on both sides of the lens cover and pull the lens cover off the projector.
     
  3. Slide the lock lever to the left.
     
  4. Insert the lens unit straight into the projector's lens socket. Make sure the two protruding points in the lens socket fit into the holes on the lens unit.
     
     

     Caution:
     Avoid touching the areas shown here or you may damage the lens unit.

  5. Hold the lens unit firmly and slide the lock lever to the right until it clicks, indicating that it is locked.
     
  6. Replace the lens cover.
     
  7. 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 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, and contact Epson.
