UV Curing System

UV Curing System
Introduction
The UV Curing System on the Océ Arizona printers generates hazardous levels of thermal,
electrical and UV energies. 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 Lamps: 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.
UV Lamp Hazards : Superficial eye damage and burning of the skin can occur with even brief
exposure to UV light. Serious injuries can result from prolonged exposure, especially if
unshielded. Special restrictions and protective measures are essential when the printers are used.
Wear Industrial Protective Eyewear with lenses that block both UVA and UVB. Gloves and long-
sleeved work clothes are essential to reduce the skin's exposure to UV emissions.
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.
Replace both lamp bulbs after 500 hours of use to help ensure that the ink in prints is fully cured.
Personal Safety
WARNING
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.
Wear Industrial Protective Eyewear with lenses that block both UVA and UVB. Gloves and long-
sleeved work clothes are essential to reduce the skin's exposure to UV emissions.
CAUTION
Warning for Seated Individuals: UV emissions are highest at a height of 90 cm (35 inches) above
the floor and increase significantly the closer you are to the lamp. This can be an issue for
individuals seated near the printer.
Remove all chairs within 5 meters (16 feet) of the printer.
