7.1 Projector Cleaning, Lens Replacement, 
      Air Intake Vent Cleaning
Clean your projector when it is dirty or image projection is poor.  Clean the air 
intake vent every 100 hours in practice.
Warning:
 No one but trained service personnel should open the projector cabinet.  The 
projector contains several high voltage components which can cause electric shock.  
For internal repairs, maintenance, and cleaning, take your projector to your vendor 
or an Epson Service Center.
 Use care when handling the power plug and connector.  Improper handling may 
cause fire or electric shock.  When handling the plug, observe the following.
· Do not insert a plug or connector into an outlet or terminal if it is dirty or holds  
foreign matter.
· Insert the plug and connector firmly and completely.
· Do not pull out the plug or connector with wet hands.
Caution:
 Never attempt to remove the lamp immediately after use.
· Heat may cause burns or other injury.
· Wait approximately 60 minutes after switching off power and remove the lamp after  
the projector has cooled completely.
 When performing operations, pull the power plug and connector out of the outlet and 
terminal respectively.
Switch off power to the projector and disconnect the power cord before 
cleaning.
Cleaning the Projector Unit
 Wipe dirt from the projector lightly with a soft cloth.
 For heavier dirt, wipe the projector lightly with a cloth soaked in a weak 
solution of mild detergent and wrung out thoroughly, then dry with a separate 
cloth.
Do not use waxes, benzene, thinners, or other volatile substances.  These may 
degrade the cabinet or strip the finish.
Cleaning the Lens
Clean the lens with a commercial blower or lens cleaning paper.  The surface of 
the lens is easily scratched and should not be rubbed or struck with hard 
objects.




						

							67
Cleaning the Air Intake Vents
Accumulated dust in the air intake vents degrades ventilation, increases the 
interior temperature, and can cause malfunction.
To prevent debris from entering the air intake vents, always stand the projector 
upright with the lens upward.  Then use a vacuum cleaner or other equipment to 
suck dust from the vents.
Point:
If it is no longer possible to remove the dirt from the air intake vent, it is time to 
replace it. Consult your vendor.

7.2 Lamp Replacement
Replace the lamp with a new lamp in the following instances.
A replacement lamp is an optional part (sold separately). 
(Model No: ELPLP13)
[When the following message is displayed for 30 seconds after projection 
begins: Lamp Replace. After the replacement of the lamp, reset the lamp 
timer under the direction in the user’s manual.]
[When the problem/alarm display indicator flashes red at 1-second intervals.]
[When brightness or picture quality is inferior to its original state.]
Point:
• If the lamp does not light, replace it even if the lamp life has not expired.
 To maintain the original brightness and picture quality, replace the lamp as soon as 
possible after a replacement message appears.
 To maintain the original brightness and picture quality, replacement messages are set 
for approximately 1,400 hours.
 Though a replacement message appears at approximately 1,400 hours, individual 
lamp characteristics or usage conditions may cause failure before 1,400 hours, and 
we recommend that a replacement lamp be kept on hand.
 A replacement lamp can be purchased from your local Epson product vendor.
Replacement
Point:
 Install the lamp securely. For safety, when the lamp cover is opened, the abnormal 
warning display indicator flashes red, and the projector lamp goes out.  If the lamp or 
lamp cover is installed improperly, the lamp will not light.
A message will be displayed.
