Projector Maintenance
You may need to clean the projector's lens periodically, and clean the air filter and air vents to prevent the projector from overheating due to blocked ventilation.
The only parts you should replace are the lamp, air filter, and remote control batteries. If any other part needs replacing, contact Epson or an authorized
Epson servicer.
Warning
Before cleaning any part of the projector, turn it off and unplug the power cord.
Never open any cover on the projector, except as specifically explained in this manual. Dangerous electrical voltages in the projector can injure you severely.
157
Cleaning the Lens
Clean the projector's lens periodically, or whenever you notice dust or smudges on the surface.
• To remove dust or smudges, gently wipe the lens with lens-cleaning paper.
• To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the lens. Do not spray any liquid directly on the lens.
Warning
Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector lamp may cause a fire.
Attention
Do not use glass cleaner or any harsh materials to clean the lens and do not subject the lens to any impacts; otherwise, it could be damaged. Do not use canned air, or the gases may leave a flammable residue.
158
Cleaning the Projector Case
Before cleaning the projector case, turn off the projector and unplug the power cord.
• To remove dust or dirt, use a soft, dry, lint-free cloth.
• To remove stubborn dirt, use a soft cloth moistened with water and mild soap. Do not spray liquid directly on the projector.
Attention
Do not use wax, alcohol, benzene, paint thinner, or other chemicals to clean the projector case. These can damage the case. Do not use canned air, or the gases may leave a flammable residue.
159
Air Filter and Vent Maintenance
Regular filter maintenance is important to maintaining your projector. Clean the air filer when a message appears telling you the temperature inside the projector has reached a high level. It is recommended that you clean these parts over a 10,000
‑ hour* or 6,000
‑ hour* period. Clean them more often than this if you use the projector in a particularly dusty environment.
* See "Projector Specifications" in the Appendix for the air filter maintenance period by model.
Attention
If regular maintenance is not performed, your Epson projector will notify you when the temperature inside the projector has reached a high level. Do not wait until this warning appears to maintain your projector filter as prolonged exposure to high temperatures may reduce the life of your projector or lamp.

c If dust is difficult to remove or the air filter is damaged, replace the air filter.
Replacing the Air Filter
You need to replace the air filter in the following situations:
• After cleaning the air filter, you see a message telling you to clean or replace it.

Projector Lamp Maintenance
163
The projector monitors the number of hours the lamp is used and displays this information in the projector's menu system.
Replace the lamp as soon as possible when the following occurs:
• The projected image gets darker or quality declines
• A message is displayed when you turn on the projector telling you to replace the lamp (the message is displayed 100 hours before the expected end of the lamp life and appears for 30 seconds)
• "Resetting the Lamp Timer" p.166
• "Projector Specifications" p.194
• "Projector Indicator Status" p.169
Replacing the Lamp
You can replace the lamp while the projector is placed on a table or mounted to the ceiling.
Warning
• Let the lamp fully cool before replacing it to avoid injury.
• Never disassemble or modify the lamp. If a modified or disassembled lamp is installed in the projector, it could cause a fire, electric shock, or other damage or injury.
a b c
Turn off the projector and unplug the power cord.
Allow the projector lamp to cool down for at least one hour.
Use the screwdriver included with the replacement lamp to loosen the screw securing the lamp cover.
• The projector's power indicator is flashing blue and its lamp indicator is flashing orange.
Attention
• If you continue to use the lamp after the replacement period has passed, the possibility that the lamp may explode increases. When the lamp replacement message appears, replace the lamp with a new one as soon as possible, even if it is still working.
• Do not repeatedly turn off the power and then immediately turn it back on.
Turning the power on and off frequently may shorten the lamp's operating life.
• Depending on the characteristics of the lamp and the way it has been used, the lamp may become darker or stop working before the lamp warning message appears. You should always have a spare lamp unit ready in case it is needed.
• We recommend the use of genuine Epson replacement lamps. The use of nongenuine lamps may affect projection quality and safety. Any damage or malfunction caused by the use of non-genuine lamps may not be covered by
Epson's warranty.

Projector Lamp Maintenance
Warning
When replacing the lamp, there is a possibility that the lamp may be broken. If replacing the lamp of a projector which has been installed on the ceiling, you should always assume that the lamp is cracked, and you should stand to the side of the lamp cover, not underneath it. Remove the lamp cover gently. Be careful when removing the lamp cover as shards of glass may fall out and could cause an injury. If any shards of glass get into your eyes or mouth, contact a doctor immediately.
e Loosen the screws securing the lamp to the projector. The screws do not come all the way out.
