• Do not move the projector while correcting the focus and keystone distortion.
2. Check the installation environment of the projector.
• Focus and keystone distortion of the projected image are automatically corrected under the
following conditions:
• When the size of the projected image (diagonal length) before correcting focus and keystone
distortion is from 30 to 100 inches.
• When the projection distance is about 28 to 87 inches (0.7 to 2.2 m).
• When the installation angle of the projector toward the projection surface is within 20º right, left,
up, or down.
• Remove any obstacles between the projector and the projection surface as these can interrupt the
projection.
Note: If you set Avoid Obstacles to On, the image is projected to avoid any obstacles in front of
the projection surface. Your image will be re-sized to fit the available area.
• Projector > Image Correction > Advanced > Avoid Obstacles
• If you are using the projector in a bright room, darken the room. Do not change the room
brightness while automatically correcting focus and keystone distortion.
• Project the image on to a plain and flat surface. Do not project the image on to a patterned surface
or a non-level surface.
Note: If you cannot correct the focus and any distortion of the projected image, turn off the projector
and disconnect the power cord, then reconnect the power cord and turn the projector back on. If a
warning screen is displayed when you turn on the projector, contact Epson for help.
