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.
Epson recommends cleaning the interior of the projector once a year. Otherwise, dust buildup could cause a fire or electrical shock.
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.
