Projector Maintenance
Your projector needs little maintenance to keep working at its best.
You may need to clean the 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 air filter and remote control batteries. If any other part needs
replacing, contact Epson or an authorized Epson servicer.
This projector uses a sealed laser light source which does not need servicing and cannot be replaced.
Warning: Before cleaning any part of the projector, turn it off, unplug the power cord, and let it cool
down. Never open any cover on the projector, except as specifically explained in this manual.
Dangerous electrical voltages in the projector can injure you severely.
Warning: Do not try to service this product yourself, except as specifically explained in this manual.
Refer all other servicing to Epson qualified servicers.
