Therefore, the problem could arise a week or two after initial use or may take months or years to surface.ДЄnecdotal reports suggest some users encountered the issue for the first time after clocking 15,000 hours.ДЄs far as specific models or series of projectors afflicted with the auto iris failure problem go, itвЂ™s across the board and quite random. Though the auto iris issue is often a result of wear, at times, it could be a direct outcome of a defective motor. How Quickly or Often Does the Auto Iris Issue Arise?

Therefore, some people may choose to turn off the feature and resort to manual iris adjustments instead or have the iris setting fixed. The iris shifting its position to accommodate the luminance of a given scene could also be a bit obvious at times. Though not an error per se, the auto iris component could make some noise while in motion, which could be distracting or annoying and may force users to turn it off. The module could be defective to begin with - a rare manufacturing oversight.The auto-iris motor may have worn out, requiring repair or a replacement.Accumulation of dust and dirt could have caused the optical block or iris motor to get stuck.Improper connection or the device may not have been plugged in correctly.The following are some of the most common causes:

The auto iris feature in most Epson projectors, particularly in the affordable range, can either be turned on or off. Irrespective of the design, the primary working mechanism of the module (as explained above) is the same. It rotates to alter the openingвЂ™s size, thereby achieving the right contrast-enhancing effect. Some other projectors (Epson or another brand) could use a wheel-like tool instead, with an aperture that shrinks gradually. Based on the imageвЂ™s requirements, the blades move in proper synchronization to decrease or increase the irisвЂ™ size. Generally, the component looks like a leaf shutter covering a camera.

If that drop in contrast ratio reads significant, you bet it is. For instance, if your projector has a 1000:1 ratio with auto iris enabled, it will likely decrease to around 700:1 when the auto iris is turned off. When the auto iris element in your projector is not working, the images will look desaturated or washed out, or the contrast ratio goes for a toss. This means dark visuals are fittingly dark, and bright scenes are well-lit, irrespective of the ambient light. In certain color modes, you may turn the auto iris setting on to optimize the image automatically depending on the projected imageвЂ™s brightness.Д®ssentially, the auto iris feature helps your Epson projector boost its contrast levels or achieve the right kind according to a scene. It closes in or narrows down when working with dark images. The task is done automatically or without any manual intervention.ДЇor bright visuals, the iris opens larger to let in more light. The mechanism helps modify the amount of light that eventually gets projected. It opens and shuts itself up based on the projected imageвЂ™s overall luminance. вЂњAuto irisвЂќ is a piece of hardware instituted between your Epson projectorвЂ™s lens and bulb.
