Cleaning the lamp filter screens
In dirty or dusty environments, the dust filter screens on the lamp module
and lamp door and in the lamp compartment
can become clogged, causing
high temperatures inside the lamp module. These high temperatures can
impact lamp performance and operating life. Routine maintenance to
remove dust and dirt from the screens lowers the lamp operating tempera-
ture and prolongs lamp life. To maximize lamp life you will need to clean
the screens every 250 hours. Lamp screen maintenance may need to occur
more often than 250 hours depending on your installation/use environ-
ment.
1 Remove the lamp module. Refer to page 40 for instructions.
2 Examine the dust filter screens on each side of the lamp module. If nec-
essary, use compressed or canned air to clean the screens. Then use a
cotton swab dipped in isopropyl alcohol to lightly wipe each screen.
After you've wiped each screen, blow away any remaining contami-
nants.
3 Before you replace the lamp, repeat the cleaning process on the screen in
the lamp compartment in the projector.
4 Examine the dust filter screen on the lamp door. If necessary, use com-
pressed or canned air to clean the screen.
5 Replace the lamp module and lamp door.
