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.
Attention:
The UV Lamps contain Mercury. Dispose according to local environmental regulations.
Personal Safety
UV Light Emissions can be harmful:
Protective measures are essential in the workplace. Use the UV safety glasses with side
shields supplied with the printer. Wear appropriate clothing that protects the skin from
UV light exposure. Keep a distance of at least 1 m (3 ft) from UV lamps while printing.
