EPSON PowerLite 8000i/9000i Projector To determine the projection distance when you know the diagonal size of the screen image: t Inches: Maximum projection distance = (1.967 × diagonal size) - 3.224 Minimum projection distance = (1.554 × diagonal size) - 3.563 t Centimeters: Maximum projection distance = (4.996 × diagonal size) - 8.1889 Minimum projection distance = (3.947 × diagonal size) - 9.0500 For example, here are the measurements for three installations: Image size (diagonal) Horizontal distance from projector to screen 300 in.* (762 cm) 200 in. (508 cm) 100 in. (254 cm) Minimum 460.6 in. (11.7 m) 307.1 in. (7.8 m) 153.5 in. (3.9 m) Maximum 586.6 in. (14.9 m) 389.8 in. (9.9 m) 192.9 in. (4.9 m) * For an image size of 320 inches, the projector may be up to 52.1 feet away from the screen, depending on the setting of the zoom ring. Long Throw Zoom Lens Calculations (ELPLL02) To determine the minimum and maximum diagonal size of an image when you know the projection distance: t Inches: Maximum diagonal size = (0.487 × projection distance) + 2.336 Minimum diagonal size = (0.286 × projection distance) + 1.458 t Centimeters: Maximum diagonal size = (1.2369 × projection distance) + 5.9334 Minimum diagonal size = (0.7264 × projection distance) + 3.7033 To determine the projection distance when you know the diagonal size of the screen image: t Inches: Maximum projection distance = (3.492 × diagonal size) - 5.091 Minimum projection distance = (1.554 × diagonal size) - 3.563 t Centimeters: Maximum projection distance = (8.8696 × diagonal size) - 12.9311 Minimum projection distance = (3.9471 × diagonal size) - 9.0500 Short Throw Zoom Lens Calculations (ELPLW01) To determine the minimum and maximum diagonal size of an image when you know the projection distance: t Inches: Maximum diagonal size = (0.876 × projection distance) + 3.793 Minimum diagonal size = (0.730 × projection distance) + 3.029 t Centimeters: Maximum diagonal size = (2.2250 × projection distance) + 9.6342 Minimum diagonal size = (1.8542 × projection distance) + 7.6936 To determine the projection distance when you know the diagonal size of the screen image: t Inches: Maximum projection distance = (1.369 × diagonal size) - 4.147 Minimum projection distance = (1.142 × diagonal size) - 4.331 t Centimeters: Maximum projection distance = (3.4772 × diagonal size) -10.5333 Minimum projection distance = (2.9006 × diagonal size) - 11.0007 Fixed Short Throw Lens Calculations (ELPLR01) To determine the diagonal size of an image when you know the projection distance: t Inches: Diagonal size = (1.239 × projection distance) + 3.415 t Centimeters: Diagonal size = (3.1470 × projection distance) + 8.6741 To determine the projection distance when you know the diagonal size of the screen image: t Inches: Projection distance = (0.807 × diagonal size) - 2.756 t Centimeters: Projection distance = (2.0497 × diagonal size) - 7.0002 Projector Status Lights The lights on top of the projector indicate the projector's operating status. Power light Projection lamp light Temperature light Caution: A red light warns you if a serious problem occurs. Power Light Light status Steady orange Steady green Flashing green Flashing orange Off Meaning Sleep mode. (The projector is plugged in, but not projecting.) Power and lamp are on. Projector is warming up. Allow about 30 seconds. Projector is cooling down. There is an internal projector problem. 4 - EPSON PowerLite 8000i/9000i Projector 10/99
