Maintenance

Maintenance
A lamp is a consumable item. If used for extended periods, images will appear dark, and 
the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The 
lifetime of the lamp depends on condition of use.) If this happens, replace it with a new one.
 WARNING
If the projector is mounted on the ceiling, it is strongly recommended that you 
contact your sales representative when the lamp has to be exchanged. Do not 
attempt to replace the lamp by yourself. 
If you uncover the lamp while the projector is mounted on a ceiling, there may be 
a danger of damage from falling pieces of glass if the lamp is broken, resulting 
in possible injury. In addition, working at high elevations can also be potentially 
hazardous. Do not attempt to replace the lamp by yourself.
Always use lamp “PJ Replacement Lamp Type1” (sold separately) when 
replacing the lamp.
Using a lamp other than the one specified may cause a malfunction or damage to 
the unit due to the difference in the connector shape or the lamp rate.
•
•
 CAUTION
If you have been using the projector, the lamp will be very hot, and may cause 
burn injuries. 
Wait 1 hour or longer for the lamp to cool before replacing it.
If the lamp should break, please handle with care to avoid injury due to broken 
pieces and contact your sales representative for repair service.

Maintenance
 Notes and Precautions
The [Lamp time] item in the Status display menu indicates the time of lamp use. (Use 
it as a rough estimate or guide for lamp life.) p.45
Please replace the lamp after 000 hours of use if [Lamp power] in the Default setting 
1 menu is set to [Standard], or after 3000 hours of use if [Lamp power] in the Default 
setting 1 menu is set to [Low]. p.42
There may be cases where the lamp stops working before the above mentioned period 
expires or before the replacement message is displayed.
Attach the outer lamp cover correctly so that it is secure and not loose. If it is not 
attached correctly, the projector may fail to turn on or the lamp may fail to come on.
Always replace the lamp with a new one.
The lamp is made out of glass. Do not touch the glass surface with your bare hands, bang 
it, or scratch it. Since dirt, jolts, scratches and other similar particles may affect the lamp.
 About lamp replacement messages
The lamp replacement message displays an appropriate period based on the 
use period selected in [Lamp power].
When the replacement time approaches, “The lamp life is ending. Please 
change the lamp.” message is displayed each time the power is turned on. The 
display disappears when you press the  button.

Air filter cleaning
The air filter prevents dust and debris from getting inside the projector. Never run the pro-
jector with the filter removed. It is recommended that you clean the air filter regularly.
• The message “
Check the air filter for dirt.” is displayed every 100 hours. (Once the 
usage time exceeds 100 hours, the message is displayed for about 30 seconds the first 
time the power is turned on and an image is displayed. The message will disappear with 
any operation.)
•  Check the filter and if any debris is found, use the following cleaning procedure.
 WARNING
• Request cleaning and maintenance of a ceiling-mounted unit from your sales 
representative. 
Attempting to clean or replace the filter in a high location by yourself may cause you 
to fall, resulting in injury.
1 Unplug power cord.
2 Remove the air filter.
Pull out the air filter by holding the release knob 
with your fingers as shown in the figure.
3 Clean the filter.
Carefully remove the dust and dirt from the air filter 
with a vacuum cleaner or the like.
4 Replace the air filter.
Insert the air filter firmly until you hear a click.
  Notes
•  When dirt and dust build up in the air filter, the air circulation inside the projector is 
affected and the internal temperature will rise, causing the projector to stop working or 
malfunction.
•  Push the air filter fully in. If the projector is used with the air filter only partially inserted, 
dust and dirt will enter the interior and this could cause the projector to stop working or 
break down.
•  If you wash the air filer with water, make sure you dry it thoroughly before replacing it.
•  If the air filter becomes damaged, replace it. Contact your sales representative for a new 
filter. If you continue to use the projector when its filter is damaged, dust and dirt will enter 
the interior and this could cause the projector to stop working or break down.

Maintenance

Lens and main unit cleaning
 WARNING
Request cleaning and maintenance of a ceiling-mounted unit from your sales 
representative. Attempting to clean the unit or replace the lamp in a high location by 
yourself may cause you to fall, possibly resulting in injury.
•
Lens cleaning
Clean the lens with a commercially available blower 
and/or lens cleaner.
The lens is easily scratched, so do not rub it with hard 
objects, or strike it.
Main unit cleaning
Always unplug the power cord before cleaning the main unit.
Wipe dirt off the main unit gently using a soft cloth.
Do not wipe the main unit with a damp cloth. 
Doing so may allow water to get inside, resulting in 
possible electric shock or unit failure.
Do not use benzene, thinner or other similar 
chemical solutions as they may deform or discolor 
the unit or damage the paint surface.
Do not use a chemically saturated cloth.
