Safety Information
This manual has three sections that contain details on safety when handling ink and
using the printer. Also, where applicable, cautions and warnings are used throughout
this manual to draw your attention to safety precautions.

Preface
■"Safety Guidelines for Ink Materials" offers advice in the proper handling of UV
inks;
■"Interlock Safety System" explains the safety features built in to the printer that
prevent and minimize access to Mechanical, Electrical, Thermal and UV hazards;
and
■"UV Curing System Safety" presents warning about the dangers of exposure to
UV light. Some of the material from that section are duplicated here.
UV Curing System Safety
Caution: UV Light Hazard: Wear Eye and Skin Protection. Eyewear,
Gloves, and Long Sleeves are essential for Users and Bystanders. Special
restrictions and protective measures are essential - These include the use of
Eye and Dermal (skin) Protection. Industrial Protective Eyewear with
lenses that block both UVA and UVB must be used. Long sleeved work
clothes and gloves are essential to reduce the Skin's exposure to UV
emissions. Avoid looking directly at UV lamps.
Caution: Warning for Seated Individuals: The UV Emissions and Blue
Light Emissions profile of the Arizona 250 GT is at its worst for individuals
in a seated position (Table Height of 90cm). Remove all chairs within 5
metres (16 feet) of the printer.
UltraViolet Light Radiation Hazards Emission:
Effective UV-irradiance Emission Category of Arizona 250 GT According to 7.1 of
EN12198-1:2000 ( Category 2 ) - Special restrictions and protective measures are
essential - These include the use of Eye and Dermal (skin) Protection. Industrial
Protective Eyewear with lenses that block both UVA and UVB must be used. Long
sleeved work clothes and gloves are essential to reduce the Skin's exposure to UV
emissions.
Blue Light Radiation Hazards Emission (Visible radiation in the range of 400nm
to 700nm (Blue Light 300nm - 700nm):
Effective Irradiance respective the Effective Radiance Emission Category of Arizona
250 GT According to 7.1 of EN12198-1:2000 (Category 1).

Preface
Customer Service
If your printer malfunctions and you are unable to resolve the problem, field service
technicians can be dispatched to your site to conduct repairs. Service visits are paid
for by the customer, either under a maintenance agreement, by purchase order or
prepayment. Time and material rates are charged for any service not covered under
a maintenance agreement. Before calling to report a problem, gather as much
information about the problem as possible and have it ready to provide to your
customer care center. The more information you can provide initially, the more
quickly the problem can be corrected.
Responsibilities of the Operator
The operator of the Arizona 250 GT must be properly trained. Océ provides training
for the operator in the use of the printer hardware and software at the time of
installation. It is the customer's responsibility to ensure that only properly trained
personnel operate the printer. Operators must be fully versed in the operation of
Onyx ProductionHouse. For any operator unfamiliar with its operation, Onyx
ProductionHousetraining is required. Training courses are available; contact your
local Océ representative.
The operator or other trained personnel are expected to handle all user maintenance
as detailed in the User Guide, and also replacement of consumable parts (except print
heads). If your site has a technician in charge of printer maintenance, that person is
the optimal candidate. While any trained operator may perform routine maintenance,
the best maintenance results from familiarity with the printer's internal operation and
history.
The printer requires daily printhead maintenance to ensure the highest print quality
and longer life for the printheads. The printer design provides you easy access to
perform this simple task. Periodic cleaning must be scheduled for some components
on a weekly basis. A few minutes spent cleaning also helps to ensure optimal printer
function and the highest quality prints.
It is the responsibility of the operator to try to eliminate simple problems before
calling a service representative. But knowing when to call for service is also
important. An untrained operator must not attempt to service the printer as this may
cause further damage. When you have determined that a service call is required, call
as soon as possible. See the Maintenance section for more details.
Responsibilities of the Arizona 250 GT Service Technician
Field service technicians must have Océ Display Graphics Systems Arizona 250 GT
service training. The service technician is responsible for all repairs, upgrading and
modification requested by the customer or mandated by the Océ Display Graphics
Systems Service and Support Group. Service personnel are furnished with proper
tools for the installation and maintenance of the printer. In addition to the tools and
custom kits, each engineer will have basic tools for proper maintenance and
servicing.

11
Preface
Statement of Foreseen Use
The Arizona 250 GT flatbed inkjet printer uses piezo printing technology and UV
curable inks to produce outdoor-durable output. It can print directly onto rigid and
flexible substrates up to 2.5 m (98.4") x 1.25 (49.2") and up to 48 mm (1.89")
thickness. The printer holds substrates stationary while the print head assembly
moves across to create the print, eliminating image skew problems often associated
with rigid stock feed systems.

Introduction
The Arizona 250 GT is a 4 color (CMYK) UV flatbed inkjet printer capable of
producing large format images on various rigid and flexible media. The printer
consists of a large vacuum table and moving gantry. The material is held flat and
stationary on the vacuum table during printing. The gantry contains a carriage that
sweeps across the table as the gantry moves in steps along the length of the table to
print an image on the media. In addition to the benefits of stationary positioning, the
use of UV ink technology on rigid material eliminates finishing processes such as
mounting and lamination.
Note: The Arizona 250 GT must be operated in accordance with the environmental
conditions specified in the Arizona 250 GT Site Preparation Guide and safety
requirements noted in this document.

Arizona 250 GT Printer Specifications
Océ VariaDotVariable Droplet Imaging Technology
The Océ Arizona 250 GT offers superior print quality and ink economy through the
use of Océ VariaDot imaging technology, the next evolution in piezoelectric inkjet
technology that enables a print head to produce droplets of varying volume. This
differs from the current piezoelectric print head technology that is restricted to the
use of fixed droplets. The use of variable sized droplets results in dots on the media
of varying size (area) and density which in turn allows the use of four-color (CMYK)
printing for all image features. Using Océ VariaDot imaging technology results in
excellent print quality and a superior ink economy over 6-color printing systems.
Océ VariaDot imaging technology allows piezoelectric print heads to produce
droplets of varying volume on demand. This allows the ONYXProductionHouse
software to specify the appropriate droplet size for each specific image feature.
When imaging fine detail such as small type or fine lines, very small droplets can be
used, when imaging areas of tonal transition or quarter-tone values such as skin tones
drops of medium volume can be used and when printing areas of high density such
as solid colors, large droplets can be used.
Océ VariaDotfor Improved Image Quality
Océ VariaDot imaging technology can be compared to painting a room in your
house. You use a large brush size for quick coverage over large areas and a much
smaller, finer brush for detailed areas. Trying to paint a large wall with a tiny brush
would result in many artefacts and trying to paint a fine fresco trim with a large brush
would be very frustrating. In the same way, Océ VariaDot uses the appropriate size
droplet for each specific image feature resulting in the best possible image quality in
every part of the printed image.
Océ VariaDotfor Reduced Ink Consumption
A significant benefit of Océ VariaDot imaging technology is that it allows the use of
only four inks (CMYK) for all areas of the printed image. This is very significant to
the user in terms of ink consumption per square meter because the current "de facto
standard" in the industry is six-color piezoelectric printing. This older technology
uses lighter versions of Cyan and Magenta inks, often referred to commercially as
"Light Cyan" and "Light Magenta" to overcome the image quality problem
previously associated with four-color (CMYK only) printing.
