Clean the Quartz Windows 5-21
Clean the Quartz
Windows
The quartz windows protect the UV lamp cartridges from ink,
media, and environmental dust. They should be checked period-
ically for dust buildup, which reduces the curing efficiency of
the UV lamps.
WARNING
UV light hazard. Excess exposure to high-intensity UV
light can result in photokeratitis (also known as
snowblindness or welder’s flash). AVOID LOOKING
DIRECTLY AT THE UV LIGHT.
VORSICHT UV Licht hoher Intensität. Bitte vermeiden Sie es,
direkt in die Lampen zu schauen.
Caution
Avoid depositing skin oils onto the quartz windows.
Skin oils left on the quartz windows could cause the
windows to shatter when heated.
Note
If the quartz window is becoming opaque (devitrifi-
cation) or is chipped, cracked, or cannot be cleaned,
then it should be replaced to ensure that the ink can
be cured.
