UV Curing System

Introduction
UV-curable ink need a high energy level of UV light to cure. The UV curing
system is made up of two mercury arc lamps attached to the carriage.
How to Handle UV Lamp: UV lamps operate at high temperatures. Never
touch a lamp in operation. Let the lamps cool for a minimum of five
minutes before attempting any maintenance. Use extreme care in handling
the UV lamp bulbs. The UV bulbs contain a small amount of metallic
mercury which is toxic when ingested, handled, or breathed. Therefore, if
bulbs are broken, care should be taken to clean up the spill immediately,
and then disposed of according to local regulations concerning Mercury
disposal.
Bare skin contact with the UV lamp bulbs must be avoided. When heated,
compounds from the skin can form permanent etching on the surface of
the UV bulb. A contaminated bulb may fail prematurely.
Ozone: As a UV lamp warms up, it briefly passes through a section of the
light spectrum which excites oxygen molecules enough to create ozone.
Once a UV lamp has completely warmed up, only very minute amounts of
ozone are present.
NOTE
A high concentration of ozone can cause irritation, headaches or nausea.
Provide adequate ventilation as indicated in the Site Preparation Guide.
CAUTION
Warning for Seated Individuals: UV emissions are highest at a height of
90 cm (35 inches) above the floor. This can be an issue for individuals
seated near the printer.Remove all chairs within 5 meters (16 feet) of the
printer.
IMPORTANT
The UV Lamps contain Mercury. Dispose according to local
environmental regulations.
Personal Safety
