5Maintenance
T
he projector needs little maintenance. You should keep the lens clean because
any dirt or stains will appear on the screen. You also need to periodically clean
the air filter, which is located at the bottom of the projector. Keeping the air filter
clean is important because a clogged air filter prevents proper ventilation, which
is necessary to cool the projector and prevent it from overheating.
You should also clean the trackball on the remote control whenever you notice
that the trackball is not rotating smoothly due to dirt and dust that have collected
on the trackball.
The only parts you should replace are the lamp, air filter, and fuse. If any other
part needs replacing, contact your ELP-3300 dealer or a qualified service person.
Whenever you clean any part of the projector, always turn off the projector and
unplug it first. 
						

							54 5  •  MaintenanceCleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. Lightly wipe the
lens surface with a soft, dry, lint-free cloth.
To remove dirt or stains on the lens, moisten a soft cloth with an alcohol-based
cleaner and gently wipe the lens surface.
Cleaning the Projector Case
To clean the projector case, first unplug the power cord. To remove dirt or dust,
wipe the casing with a soft, dry, lint-free cloth. To remove stubborn dirt or stains,
moisten a soft cloth with water and a neutral detergent. Then wipe the casing.
Do not use alcohol, benzine, thinner, or other chemical detergents. These can
cause the casing to warp.
Cleaning the Air Filter
The air filter, which is located at the bottom of the projector, should be cleaned
after every 100 hours of use. If it is not cleaned periodically, it can become
clogged with dust and prevent the projector from being ventilated properly. This
can cause overheating and damage the projector.

4. The filter is attached to the other side of the filter cover. To clean the filter, it is
recommended that you use a small vacuum cleaner designed for computers
and other office equipment. If you don’t have one, use a dry, lint-free cloth.
If the dirt is difficult to remove or if the filter is torn, replace it. Contact your
ELP dealer or call EPSON Accessories at (800) 873-7766 to obtain a new one.
Be sure to request part number 1023658.

Cleaning the Trackball
You should clean the trackball periodically and whenever you notice that it is not
moving smoothly.
1. Turn off both the projector and the computer.
2. Turn the frame that surrounds the trackball counterclockwise until it unlocks.
You may need to use a sharp object, such a pencil, to help turn the frame.

                3. Lift out the trackball from its holder and wipe it completely with a soft, dry
cloth to remove dirt and grit. To remove stubborn dirt and stains, moisten the
cloth with a neutral detergent. Do not use an alcohol-based cleaner.
4. Use a cotton swab to gently clean the trackball holder. Pressing too hard can
cause the holder to move out of position.
                  5. Place the trackball back into its holder and rotate its frame clockwise until it
locks in place.
