UV Lamp Overview 3-3
UV Lamp Overview
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 require a separate power supply from the printer, to
light the lamps and ensure adequate curing. They 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.
You should be aware of the following characteristics of these
lamps when operating the printer:
WARNING
UV light hazard. The UV parking station must be
installed during printing. 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 LAMPS.
VORSICHT UV Licht hoher Intensität. Bitte vermeiden Sie es,
direkt in die Lampen zu schauen.
◆
UV light exposure — the printer is designed with shields,
louvers, and other features to protect the operator from
exposing the eyes and skin to high levels of UV radiation. The
printer must be operated with the UV parking station
installed. Do not look directly at the UV light.
◆
High/low lamp operation — the UV lamps are operated at
high intensity only when curing the ink. When the carriage is
not directly over the media, the lamps are switched to a
lower intensity.
◆
Warm-up/cool down cycle — the UV lamps take about one
minute to warm up to operating temperature, and about
three minutes to cool down fully. After printing, the lamps
must fully complete their controlled cool-down cycle before
warming up again for the next print job (for a total elapsed
time of about four minutes).
To save time, you can manually switch on or off the lamps
on the Front Page screen of the control panel (see “Front
Page” on page 2-4).
