 Replacing the lamp
The lamp used as a light source in the DPX-1200 is a consumable item which will gradually lose its brightness during the course of use. It is
advisable to replace the lamp when running time has exceeded 2000 hours.
You can check the lamp running time in the [Lamp Running Time] in the [Initial] menu group of the Menu screen. The LAMP warning
indicator will blink when running time exceeds 2000 hours.
There will also be a message displayed on the screen. In this case, follow the instructions below to replace the lamp cartridge. For details on
replacement of lamp cartridges, consult the store where you purchased the DPX-1200.
Warning
•Be sure to use the replacement lamp cartridge PJL-427. Other lamp cartridges are not suitable for use in the DPX-1200.
•If replacing the lamp of the projector that has been installed to the ceiling, you should remove the projector from the ceiling before
replacing the lamp.
•Before starting to replace the lamp cartridge, turn off the power, disconnect the power cable after the fan has completely stopped,
and wait at least one hour for the lamp to cool down.
•Do not remove any other screws than those specified in the following steps.
•The gases inside the lamp contain mercury vapor. Be careful the lamp may break if it gets old or overtasked. The life of a lamp
differs depending on operation environments.
1. Loosen the lamp cover screws.
2. Remove the lamp cover.
3. Loosen the screws of the lamp cartridge.
4. Grip the handle and pull the lamp cartridge to remove it.

•This unit uses a DMDTM chip for the picture display. Their highly accurate technology makes it possible to keep more than 99.99% of
effective pixels, however, unexpectedly it can produce less than 0.01% of ineffective pixels. In such a case, missing or flashing of a
few pixels can be found on the screen. These are characteristics of DMD
TM  , not mechanical problems.
