Replacing Color Wheel
The NP4001/NP4000 projector comes with a four-segment color wheel installed. An addi-
tional
six-segment color wheel comes included. To replace the color wheel (located under the lamp
cover adjacent to lamp 1) refer to the following guide.
Note:
• Before replacing the color wheel, be sure to turn off the projector, wait until the
cooling fans stop, and turn off the main power switch.
• Wait until the lamp house and the color wheel cool off. •
• Do not touch the disk of the color wheel. Doing so may scratch the disk or leave
fingerprints, causing the image quality to degrade.
• Heed the following information if you own two or more NP4001/NP4000 projec-
tors:
When replacing or re-installing the color wheel, the original color wheel pre-
installed or supplied as an accessory must go back to its original projector. Your
color wheel and projector color wheel cover are given an identification number. Be
sure to use the color wheel pre-installed or supplied with your projector to match
its identification number.
If you remove a color wheel from one NP4001/NP4000 projector and re-install it
into another NP4001/NP4000 projector, performance may be compromised.
