Maintenance and Cleaning
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean the optical unit. Cleaning with air spray 1. Remove the cabinet top following to "Mechanical Disassemblies". 2. Clean up the LCD panel and polarized glass by using the air spray from the cabinet top opening. Caution: Use a commercial (inert gas) air spray designed for cleaning camera and computer equipment. Use a resin-based nozzle only. Be vary careful not to damage optical parts with the nozzle tip. Never use any kind of cleanser on the unit. Also, never use abrasive materials on the unit as this may cause irreparable damage. Disassembly Cleaning Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be sufficiently cleaned by air spraying alone. Be sure to readjust the optical system after performing disassembly cleaning. 1. Remove the cabinet top and main units following to "Mechanical Disassemblies". 2. Remove the optical base top following to"Optical Unit Disassemblies". If the LCD panel needs cleaning, remove the LCD panel unit following to "LCD panel/Prism ass'y replacement". 3. Clean the optical parts with a soft cloth. Clean extremely dirty areas using a cloth moistened with alcohol. Caution: The surface of the optical components consists of multiple dielectric layers with varying degrees of refraction. Never use organic solvents (thinner, etc.) or any kind of cleanser on these components. Since the LCD panel is equipped with an electronic circuit, never use any liquids (water, etc.) to clean the unit. Use of liquid may cause the unit to malfunction.

Maintenancw and Cleaning
Cleaning the RGB panels
Blemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of the screen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality. This projector is equipped with the RGB panel cleaning holes on the bottom for cleaning of the internal parts (such as optical components) of the projector. When you use the projector for a lengthy period of time or a shadow of dust appears on the projected screen, clean the inside of the projector. Using the supplied air blower and with the Cleaning function in the Setting Menu, you can remove the dusts from the projector.
Note:
· Dust might not be removed completely with these steps. In that case, contact the dealer where you purchased the projector or service center.
CAUTION IN USING THE AIR BLOWER AND THE NOZZLE Turn the projector over when using the blower. Use only the supplied air blower and nozzle to keep the projector from being out of oder or CAUTION damaged. We could not guarantee the malfunction or breakage caused by other tools. Never use a commercially available compressed air duster. It causes the interior of the projector to malfunction with release of cold liquid propellant. Put the projector on a soft cloth to prevent scratching the surface. PROHIBITED Open the hole cover only when you clean the inside of the projector. Do not look into the holes. A strong light could damage your eyes. (Do not look into the Air intake vent and Exhaust vent, either.) Use the blower and nozzle only to clean the projector. Do not attempt to use them for other purposes. Do not use the blower and nozzle against persons (particularly to eyes, mouth or ear, and so on). Be especially careful to ensure that children do not put the blower and nozzle into their mouth and swallow them. Do not attempt to pull the nozzle out of the blower. If the nozzle happened to be pulled out, put it back into the blower immediately. Do not use the blower supplied with this projector (model: Z5/Z5BK) to clean the other models: Z4, Z3, and Z1X. In the unlikely event that something goes wrong (smoke, a strange sound, an abnormal odor, and such) while you are cleaning, turn off and unplug the projector immediately, then call the dealer where you purchased the projector or service center.
If the nozzle is pulled out ....
The nozzle has the stopper. Put the stopper-side of the nozzle into the blower. Put the nozzle firmly into the blower until the stopper becomes invisible. When putting the nozzle into the blower, hold near the stopper so that it will not break. Make sure not to attempt to pull the nozzle out of the blower.
