Replacing the exposure
lamps
5-26
The exposure system consists of four long-life fluorescent lamps.
There are two lamp housings; one upper and one lower. Each lamp
housing contains two lamps.
Change the lamps every 500 hours, when image quality appears to be
degrading (and standard maintenance procedures do not improve the
image quality), or when requested to do so by an operator message.
Always replace both lamps in a housing at the same time, or
exposures may appear inconsistent. Always use the recommended
lamps, or image quality may be unacceptable.
NOTE: If the replacement lamp is a different color than the lamp
being replaced, contact your service representative to
perform required power supply adjustments.
1. Turn the side panel switch off.
2. Open the right-side access door.

IMPORTANT: Use care when handling the imaging guides. Hold
the imaging guides by the green handles only .
4. Grasp the tab at the end of the upper lamp housing and slide the
housing out of the track.

WARNING: Make sure the lamps are cool before attempting
