Epson PowerLite 7900p Projector
Cleaning the Air Filters and Vents
Clean the air filters and air intake vents after every 100 hours of use. If they are not cleaned periodically, they can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector.
Follow these steps:
1.Turn off the projector and unplug the power cord.
2.To clean the intake vents, Epson recommends using a small vacuum cleaner designed for computers and other office equipment. If you don’t have one, gently clean the vents with a soft brush (such as an artist’s paintbrush).
3.Gently turn the projector over and remove the filters from the side and bottom of the projector. Then use a small vacuum cleaner or soft brush to clean the two filters. Slide the filters back into place when you’re done.

Replacing the Lamp and Air Filters

❏The message LAMP REPLACE appears on the screen when
the lamp comes on (after about 1900 hours) and the
lamp warning light is flashing orange. To maintain projector brightness and image quality, replace the lamp as soon as possible.
❏The 
lamp warning light is flashing red (the lamp is burnt out).

1.Turn off the projector.
2.When the P power light stops flashing, unplug the power cord.
