EPSON PowerLite 7850p Projector 6/03 EPSON PowerLite 7850p Projector - 3 Positioning the Projector Follow these guidelines: ❏Place the projector on a sturdy, level surface, between 2.6 and 36 feet from the screen. Image size generally increases with distance, but may vary depending on the position of the zoom ring and other settings. ❏Place it within 10 feet of an electrical outlet or extension cord and 5 feet of your computer or video source. ❏Allow space for ventilation around and under the projector. ❏To avoid a keystone shaped image (an image that is wider on one side), place the projector directly in front of the center of the screen, facing the screen squarely. ❏If possible, place the projector level with the bottom of the screen. If you place the projector too far below the screen, you may have to tilt it up by extending the front adjustable foot (see page 7). This causes the projected image to lose its shape, but the projector automatically compensates. If the image is still not square, adjust it manually by pressing the Keystone buttons (see page 7) or using Quick Corner (see page 8). If you place the projector higher than the bottom of the screen, the image will be square, but it won’t fill the screen. Calculating Image Size and Projection Distance Use the formulas below to find out how large the image will be when you know the distance from projector to screen, or to find out how far from the screen to place the projector if you want an image of a certain size. Since you can change the image size by rotating the zoom ring, formulas are given for calculating both minimum and maximum sizes. Note: Formulas given here apply only when the image is not tilted. If you tilt the image up by extending the projector’s foot or using electronic keystone correction, your image size may vary. Standard Lens To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = ((2.54 × projection distance) / 100) × 36) + 2.13 ❏Minimum diagonal size = ((2.54 × projection distance) / 100) × 26.84) + 1.29 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = ((diagonal size – 1.29) / 26.84) × 100 / 2.54 ❏Minimum projection distance = ((diagonal size – 2.13) / 36) × 100 / 2.54 Middle Throw Lens (V12H004M03) To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = ((2.54 × projection distance ) / 100) × 27.42) + 1.49 Minimum diagonal size = ((2.54 × projection distance) / 100) × 20.48) + 1.1 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = ((diagonal size – 1.1) / 20.48) × 100 / 2.54 ❏Minimum projection distance = ((diagonal size – 1.49) / 27.42) × 100 / 2.54 Long Throw Zoom Lens (V12H004L05) To determine the diagonal size of an image (in inches) when you know the projection distance: ❏Maximum diagonal size = ((2.54 × projection distance) / 100) × 20.4) + 1.93 ❏Minimum diagonal size = ((2.54 × projection distance) / 100) × 15.23) + 1.45 To determine the projection distance (in inches) when you know the diagonal size of the screen image: ❏Maximum projection distance = ((diagonal size – 1.45) / 15.23) × 100 / 2.54 ❏Minimum projection distance = ((diagonal size – 1.93) / 20.54) × 100 / 2.54 2.6 to 3.5 ft 7 to 9.5 ft 27 to 36.1 ftDistance from screen

EPSON PowerLite 7850p Projector 6/03 EPSON PowerLite 7850p Projector - 7 Adjusting the Image Once you see your image, you may need to make certain adjustments. Focusing and Zooming Your Image Use the focus ring on the projector to sharpen the image. Use the zoom ring on the projector to reduce or enlarge the image. Move the tab toward the W to make it bigger, or toward the T to make it smaller. If the image still isn’t large enough, you may need to move the projector farther away from the screen. You can also use the E-Zoom buttons on the remote control to zoom in on a portion of the image. Adjusting the Height of Your Image If the image is too low on the screen, you can raise it by adjusting the front foot: 1. Stand behind the projector. Press the blue foot release lever up and lift the front of the projector. 2. Once the image is positioned where you want it, release the lever to lock the foot in position. 3. If necessary, you can fine- tune the height by turning the projector’s rear feet. Raising the projector causes the image to distort or “keystone,” but you can manually correct the shape as described in the next section. Adjusting the Image Shape In most cases, you can maintain a rectangular image by placing the projector directly in front of the center of the screen with the base of the lens level with the bottom of the screen. Even if the projector is slightly tilted (within a range of 40° up or down), the projector’s automatic keystone correction function detects and corrects vertical keystone distortion. It takes about one second after projection starts for the image to be corrected. During this time, a vertical keystone correction gauge appears on the screen. If your image is still distorted, you can correct it using either of these methods: ❏If the image has two parallel sides but is wider on the top, bottom, left, or right, you can correct it using the Keystone keys on the projector’s control panel or the Keystone menu (see “Using Keystone Correction” on page 7). ❏If the image has no parallel sides, you can adjust its shape using Quick Corner ™ (see page 8). You cannot use both keystone correction and Quick Corner at the same time. Using Keystone Correction To adjust your image when it is wider on one side, do one of the following: ❏Look at the shapes of the icons on the projector’s four Keystone buttons. Press the button whose icon is the opposite shape of your screen image. Continue pressing the button until you are satisfied with the shape of the image. Focus ring Zoom ring Projector foot Corrected image Projector tilted up Projector tilted down Quick Corner correctionKeystone correction Keystone correction
EPSON PowerLite 7850p Projector 8 - EPSON PowerLite 7850p Projector 6/03 Note: The image will be slightly shorter after adjusting. If it’s important to maintain the correct aspect ratio, use the menu system to perform keystone correction, as described below, then adjust the Height setting as needed. ❏Press the Menu button on the remote control, select the Setting menu, and press Enter. From the Setting menu, select H/V-Keystone in the Keystone menu and press Enter. Select V-Keystone (for vertical keystone distortion) or H-Keystone (for horizontal keystone distortion) and press Enter. Use the pointer button on the remote control to adjust the keystone setting as needed. Using Quick Corner Use Quick Corner to correct the image shape when it’s uneven on all sides. 1. Press the Menu button on the remote control (or on the projector’s control panel). 2. Select the Setting menu and press Enter. 3. From the Setting menu, select Keystone and press Enter. 4. Select Quick Corner and press Enter. You see this screen: 5. Press the Enter button to select the corner you want to adjust. 6. Use the pointer button on the remote control (or the arrow buttons on the projector) to adjust the shape. 7. Repeat steps 5 and 6 as needed to adjust any remaining corners. 8. When done, press the ESC button on the remote control to exit the menu system. If Quick Corner remains selected in the Keystone menu, the Quick Corner screen appears whenever you press the projector’s Keystone buttons. You can then follow steps 5 through 8 above to correct the shape of your image, or press ESC to exit Quick Corner.Correcting Computer Images If you’ve connected a computer and the image doesn’t look right or fit properly on the screen, press the Auto button on the remote control (or the Auto/Enter button on the projector’s control panel). This automatically resets the projector’s tracking, sync, resolution, and position settings. Note: You must be projecting an image for this button to have any effect. The Auto button works only with computer images. If vertical stripes appear in the projected image and the Auto button doesn’t correct the problem, hold down the Shift button on the projector’s control panel while pressing either the Tracking + or the Tracking – button. If the image appears fuzzy or flickers and the Auto button doesn’t correct the problem, hold down the Shift button while pressing either the Sync + or Sync – button. Note: Also make sure you have selected the correct Computer or BNC Input option in the Setting menu for your computer. See the User’s Guide for more information.
