Epson PowerLite 755c/765c Projector Cleaning and Replacing the Air Filter Clean the air filter and air vents on the bottom of the projector after every 100 hours of use. If not cleaned periodically, they can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector. 1. Turn off the projector, allow it to cool down, and unplug the power cord. 2. Turn the projector upside down. Use a small vacuum cleaner designed for computers and other office equipment. If you don't have one, use a very soft brush (such as an artist's brush). If dirt is difficult to remove or the filter is torn, replace it. The air filter set (part number V13H134A08) contains two filters. See "Optional Accessories" on page 25 for ordering information. 3. If you need to replace the filter, slide it off as shown. Replacing the Lamp The projection lamp typically lasts for about 2000 hours of use (in High Brightness mode) or 3000 hours (in Low Brightness mode). It is time to replace the lamp when: ❏ The projected image gets darker or starts to deteriorate. ❏ The lamp light is flashing orange. ❏ The message Replace the Lamp appears on the screen when the lamp comes on. To maintain brightness and image quality, replace the lamp as soon as possible. See page 25 for ordering information and request part number V13H010L32. Note: You can check how many hours the lamp has been used in the Info menu. Caution: Turn the projector off when not in use. Continuous use may reduce the life of the product. Follow these steps to replace the lamp: 1. Press the P Power button twice to turn off the projector. When the Power light stops flashing, unplug the power cord. 2. If the projector has been on, allow it to cool down for at least an hour (or until the lamp is cool). Warning: Let the lamp cool before replacing it. In the unlikely event that the lamp has broken, small glass fragments may be present and should be removed carefully to avoid injury. 3. Turn the projector over. Press in on the tabs and lift up the lamp cover. 4. Slide the new air filter until it clicks in place. 8/05 Epson PowerLite 755c/765c Projector - 23
