UV Lamp Operation
and Maintenance
The printer’s two UV lamps (on the left and right sides of the
printhead carriage) emit the high-intensity ultraviolet light that is
necessary to cure the UV ink.
The lamps have a limited life, during which the amount of UV
light emitted slowly decreases, eventually reaching a level that
will no longer cure the ink. There are measures you can take to
extend the service life of the lamps, but they will eventually have
to be replaced.
WARNING UV light hazard. Excess exposure to high-intensity
UV light can result in photokeratitis (also known as
snow blindness 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 Failure to allow the lamps to cool down properly, as
described on the control panel, will damage the
lamps.
Operating Tips When the lamps do not cure output sufficiently in Billboard Qual-
ity Mode, switch to Production Quality Mode. When the lamps do
not cure the output in Production Mode, switch to High Quality
Mode (Front Page > Print Mode).
If the lamps are not curing the ink with the lamps set to Low,
increase the setting to Medium or High (Front Page > Print
Mode > Select Print Mode > Select Print Direction > Print
Mode Options > Lamp Modes).
If the lamps are still not curing printed output after taking these
steps, replace the bulbs.
Replacing UV Lamp
Bulbs
The UV lamp bulbs will gradually lose their intensity and there-
fore their ability to cure the ink. The control panel will display a
warning message when one or both of the bulbs have been
operated for 500 hours, but the bulbs may continue to cure
printed output for up to 1000 hours. To view the number of hours
