■ Image Quality Maintenance

Clearing Afterimages (Refresh Mode)
If you project still images for an extended period of time, an afterimage may remain in the projected image.
Use the Refresh Mode feature to clear it.
To use the effect functions, make sure you perform Refresh Mode regularly.
To perform refresh mode, select [Refresh Mode] from the projector's [Management] menu.
After performing Refresh Mode, the power turns off after a set time has passed.
If the afterimage remains after performing Refresh Mode, contact Epson for help.
Adjusting Color Balance (Light Source Calibration)
By performing light source calibration, the difference between the white balance and the brightness level for the light source is
corrected.
We recommend performing light source calibration periodically.
To perform light source calibration, select [Light Source Calibration] from the projector's [Management] menu.
Select one of the following [Light Source Calibration] options.
Projection is temporarily interrupted while light source calibration is being performed.
• [Run Now]
Starts light source calibration immediately. You may not be able to start the calibration in the following situations.
- Within 20 minutes of turning on the projector.
- When the environmental temperature is high and the brightness of the light source is automatically reduced.
• [Run Periodically]
Set to [On] to perform light source calibration periodically every 100 hours of usage.
Set to [Off] to prevent light source calibration from starting unexpectedly while projecting images.
Set to [Off] to maintain the projected image that was adjusted using multi-projection.
Light source calibration will not start automatically in the following cases:
- Within 20 minutes of turning on the projector.
- When the environmental temperature is high and the brightness of the light source is automatically reduced.
- When using direct shutdown
- When the projector has been in use for more than 24 hours
• [Last Run]
