Maintenance
This section describes maintenance tasks such as cleaning the projector and 
replacing consumable parts.
Cleaning
You should clean the projector if it becomes dirty or if the quality of projected 
images starts to deteriorate.
Be sure to read the separate Safety Instructions/World-Wide Warranty 
Terms for details on safe handling of the projector during cleaning.
Clean the projector case by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water containing a 
small amount of neutral detergent, and then firmly wring the cloth dry before 
using it to wipe the projector case. Then wipe the case again with a soft, dry 
cloth.
Caution :
Do not use volatile substances such as wax, alcohol or thinner to clean the projector 
case. These can cause the case to warp and make the coating finish peel off.
Use a commercially-available air blower, or use a lens cleaning paper to gently 
wipe the lens.
Caution :
Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily 
become damaged.

If the air filter becomes clogged with dust, it can cause overheating and damage 
the projector.
Stand up the projector in order to prevent dust getting inside the projector, and 
then use a vacuum cleaner to clean away the dust from the air filter.
Tip :
 If the air filter is difficult to clean or if it is broken, it should be replaced. Contact your 
dealer for a spare air filter.
 Replacement lamps are provided with a spare air filter. The air filter should also be 
replaced when the lamp is replaced.

Replacing Consumables
This section describes how to replace the lamp and the air filter.
It is time to replace the lamp when:
The message Lamp Replace appears on the screen for 30 seconds 
when projection starts.
The lamp indicator flashes orange or lights red.
The projected image gets darker or starts to deteriorate.
Tip :
 In order to maintain the brightness and quality of the projected images, replace the 
lamp as soon as possible after the warning message appears.
 The replacement warning message is set to appear after 1400 hours of lamp use in order 
to maintain the brightness and quality of the projected images. If you continue to use the 
lamp after this period, the possibility of the lamp breaking becomes greater. When the 
lamp replacement message appears, replace the lamp with a new one as soon as 
possible, even if it is still working.
 The warning message appears after 1400 hours of use, but the actual life of each 
individual lamp will vary depending on the characteristics of the lamp and on the way 
it has been used. Some lamps may stop operating before 1400 hours of use, so you 
should always have a spare lamp ready in case.
 When the lamp replacement warning message appears, the user’s logo will not appear 
even if the start-up screen setting is ON. 
 Contact your dealer for a spare lamp.
Lamp Replacement Period
A message will be displayed.

Caution :
If the lamp stops working and needs to be replaced, there is the danger that the lamp 
may break when handled.
If replacing the lamp of a projector which has been installed to the ceiling, you should 
always assume that the lamp is broken and handle it with extreme care during removal.
Furthermore, you should stand to the side of the projector, not underneath it.
Procedure
1Turn off the projector power, wait 
for the cool-down
 period to end, 
and then disconnect the power 
cord.
The cool-down period lasts for about 2 
minutes. The actual time will vary 
depending on the external air temperature.
2Wait until the lamp has cooled 
down, and then remove the lamp 
cover.
It takes approximately 30 minutes for the 
lamp to cool down by itself.
Use the screwdriver that is provided with 
the replacement lamp to slide the lamp 
cover opening switch so that the lamp 
cover lifts up. Hold the raised section of 
the lamp cover and then slide it forward to 
remove it from the projector.
3Loosen the two lamp fixing screws.
Use the screwdriver that is supplied with 
the replacement lamp to loosen the two 
lamp fixing screws that are securing the 
lamp to the projector.

or the lamp cover is not installed correctly.
 Replacement lamps are provided with a spare air filter. The air filter should also be 
replaced when the lamp is replaced.
 Dispose of used lamps properly in accordance with your local regulations.
