Starting the projector up in “Safe” mode is a quick and highly effective solution for the persistent Auto Iris issues.

If disabling the feature doesn’t work for you as you have a use for it, there’s a method to bypass the feature’s confirmation via a specific button combination on the projector.

  5. Simultaneously press the “Power” button on the remote.
  6. Release after 5–6 seconds and wait for the device to start.

It may take between 10 and 15 seconds for the Epson projector to start off of that sequence but do not press any other buttons until it does. 

Note: Additionally, ensure you receive the Auto Iris error, before shutting down the projector and attempting to start the device in “Safe” mode.
