Replacing the Lamp
All projector lamps will wear out eventually. If used for long periods of time, the image could become
darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps
early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up
the projector, the lamp needs to be replaced. (See "Related Messages" and "Regarding the Indicator
Lamps" for details.)
Turn off the projector, and unplug the power
1
cord. Allow the lamp bulb to cool for at least
45 minutes, and prepare a new lamp (sold
separately: DT00511 for CPS317/EPS3170/EPS3170A
or / DT00521 for CPX327/EDX3270/EDX3270A)
After making sure that the projector has

cooled adequately, slowly flip over the
projector, so that the bottom is facing up
Unscrew the 2
3
screws, and
remove the
lamp cover
Unscrew the 1 screw, and slowly pull

out the lamp by the handle
• Be careful not to touch the inside of the lamp case.
ATTENTION
• Do not use with lamp cover removed.
• Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing
the lamp. The message functions will not operate properly if the lamp timer is not reset correctly.
• When the lamp has been replaced after the message of "CHANGE THE LAMP ...THE POWER
WILL TURN OFF AFTER 0 hr." is displayed, or the LAMP indicator is red, complete the following
operation within 10 minutes of switching power ON.
NOTE
Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power
ON again. If the LAMP indicator is still red, replace the lamp.
