Customer Support
Océ maintains a comprehensive support structure for its Arizona T220UV customers. Upon installation of your printer, you
will be provided with the name of the sales and service office responsible for your account. Record this information, along
with the serial number of your Arizona T220UV. Always report service problems to the office assigned to your account at
installation.
Customer Service
When you call our customer service number you will be provided with telephone technical support. Outside of office hours,
you can leave a message and your call will be returned the next working day. When you call, identify yourself as an Arizona
T220UV customer and provide the following information:
• The serial number of your Arizona T220UV
• Your company name and your name
• Your telephone number
• Nature of the problem
If we are unable to resolve your problem over the telephone, field engineers 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 the customer care center
engineer. The more information you can provide initially, the more quickly the problem can be corrected.

Introduction 7
Responsibilities of the T220UV Operator
The operator of the Arizona T220UV must be properly trained. Océ provides training for the operator in the use of the
Arizona T220UV 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 of the Arizona T220UV should be fully versed in the operation of Onyx PosterShop® . For any operator unfamiliar
with its operation, Onyx PosterShop® training is required. On-site or off-site training courses are available; contact Onyx
Graphics Corporation for more information:
http://www.onyxgfx.com/support_training.html
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 Arizona T220UV printer requires some daily maintenance. Periodic cleaning must be scheduled for some components
on a weekly basis. A few minutes spent cleaning ensures the highest quality prints. Several areas require maintenance to
ensure the highest print quality, and the printer design gives you easy access to all these areas. Refer to the Arizona T220UV
User Guide for details.
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 T220UV Service Technician
Field service technicians must have Océ Arizona T220UV service training. The service technician is responsible for all
repairs, upgrading and modification requested by the customer or mandated by the Océ Service and Support Group.
Service personnel are furnished with proper tools for the installation and maintenance of the Arizona T220UV printer. In
addition to the T220UV tools and custom kits, each engineer will have basic tools for proper maintenance and servicing.
An Océ help desk consultant initially screens all customer calls. This means that a trained Océ Arizona T220UV specialist
with system training handles the calls and helps you understand your problem or situation. This process minimizes the
number of print quality issues that are not directly related to hardware. All hardware problems are dispatched to field service
technicians. If an on-site visit is required, the help desk technician can recommend parts which then can be ordered, thus
increasing efficiency in the service cycle.
Statement of Foreseen Use
The Océ Arizona T220UV 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 62 inches wide by 120 inches long by 2
inches thick (1.6 m x 3 m x 5 cm).
The Océ Arizona T220UV holds substrates stationary while the print head assembly moves across to create the print,
eliminating image skew problems associated with rigid stock feed systems. It can print full bleeds, saving time and labor
costs in finishing.
With four print heads per color, the Océ ArizonaT220UV can produce prints at a production speed of up to 180 square feet
(16.7 m2) per hour. It includes the unique Océ ColorBlend® super-CMYK technology, for an apparent resolution of 600 dpi.
The Océ Arizona T220UV uses UV curable pigmented inks, and can print directly onto a variety of uncoated rigid or flexible
substrates such as foam-core style mounting board, PVC sheets, styrene, aluminum-plastic composites and vinyl.

Viewing Specifications (8 pass mode only)
Note: This viewing specification is based on the Océ reference print, imaged on the provided Indoor/Outdoor Poster Grade
Paper (Part # 3010102610).
Banding artifacts - not visible from 8 feet (Texture or Regular Banding).
Non-Banding artifacts - not visible from 3 feet (fisheyes, orange peel).
Océ ColorBlend® Six-Color Printing
Océ ColorBlend® technology uses the printer’s fifth and sixth ink stations to provide the appearance of continuous tone
color. It does this by adding lighter density cyan and magenta inks to the basic four CMYK (cyan, magenta, yellow and black)
inks to create a smoother appearance in the light and midtone colors, a wider color gamut and crisper detail. The result is
near-photographic quality output without the requirement of extremely high resolution or true continuous tone.

Safety Guidelines
Introduction
Read all of the material in this section and review the MSDS documents before handling any UV ink or using the T220 UV
printer.
Caution: Both UV inks and the curing lamps can be harmful if not properly handled. Follow these guidelines carefully in
order to ensure maximum safety.
Personal Safety
The operator should wear butyl rubber gloves, a protective apron, a NIOSH-approved respirator (half-mask organic vapor
respirator), and Safety glasses with side shields when handling inks.
Personal Safety
The Arizona T220UV printer has an integrated safety interlock system that stops all machine motion when a situation that
might compromise operator safety occurs. Thus, opening any of the gantry doors (except during authorized procedures),
tripping the hinged gate on the gantry cover, or activating an Emergency-Stop button will switch the Safety Monitoring
Relay input circuits. This results in the system isolating the power to both the motion control motors and the T220UV curing
system (lamps). For a general description of how the safety interlock system works, see “Safety Interlocks” and for a detailed
technical description see Appendix B.
Handling UV Inks
Read and practice safety guidelines as outlined in the Material Safety Data Sheet (MSDS) for each ink. Post these documents
in the work area as required by prevailing law. MSDS for all six inks are provided when you purchase inks. The following
is a summary of the important safety aspects of the MSDS that are common to all UV inks.

Safety Information 19
UV Lamp Safety
Introduction
The Arizona T220UV printer is designed so that direct light from lamps is not visible and bounce (reflected) light is
minimized. UV lamps radiate harmful ultraviolet rays, which can cause serious burns to skin and eyes. While thermal burns
are felt immediately, UV burns are not felt for several hours. Short exposure to lamp radiation can cause severe burning of
skin and eyes. UV burn of the eyes affects the cornea and takes several days to heal. UV burn is identical to "Welder's burn"
and will feel like sand in the eyes that cannot be washed out. The discomfort is transitory. Extreme caution must be taken -
high power UV radiation can cause blindness.
Limited exposure to UV radiation will evoke erythema on normal skin. Such erythema is transitory and will not produce
blistering, nor tanning, as only a small amount of radiation penetrates the Malpighian layer. Extreme caution must be taken
since high power UV radiation can cause severe burns to the skin.
Note: The Arizona T220UV printer has a built-in interlock safety system that shuts down the UV lights if the gantry doors are
opened. This ensures that the operator is not exposed to potentially harmful UV rays from the lamps. The section “Safety
Interlocks” explains the interlock system and how it protects the operator from UV exposure.
Statement of UV Safety
UV Lamps: 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. Some UV lamps operate at very high temperatures
(approximately 800° C). For this reason, never touch a lamp which has been in operation. Let the lamp cool before attempting
any maintenance, and then use extreme care in handling the bulbs. Most 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.
The UV Lamps emit dangerous levels of UV light. Arizona T220UV operators must limit their exposure to UV/Blue light
escaping from beneath the gantry hinged gates. The UV Radiation Hazards of the machine have been measured according
to EN12198 and are at safe levels outside the machine.
Gantry Cover Brush: The Brushes are used as a UV Shield to prevent stray UV light escaping from the front and back of
the gantry, while still allowing adequate media clearance. The brushes must be replaced if they become contaminated or
deformed by any means. The brushes must be replaced at least every two years, or sooner if they become contaminated or
deformed in any way.

Effective Irradiance respective the Effective Radiance Emmision Category of AzT220UV According to 7.1 of
EN12198-1:2000 Category (1)
Handling UV lamps
Bare skin contact with the UV lamps must be avoided. Replacement lamps must be wiped with the supplied cleaning solution
before placing in service. Compounds from the skin when heated on lamps operating at 600 to 850C will form permanent
etching (devitrification) on the quartz surface decreasing UV energy transmission. A contaminated lamp eventually may
overheat, causing premature failure.
When unpacking the lamps, the carton should be opened fully so lamp can be lifted out of packaging with no twisting or
pulling. Unpacking should take place in an area large enough to eliminate the possibility of inadvertently striking lamp
against walls, pillars, pipes, beams or press machinery.
Ozone Safety
Tri-atomic oxygen or ozone (O3) is the only by-product of the UV lamp. It is formed by oxygen being exposed to 254nm
wavelengths of UV energy. Ozone is effectively eliminated in the printing area by exhausting air from the cooling system of
the T220UV. Such exhausting involves no danger as the hot gas is very unstable and breaks down to oxygen rapidly in
ducting. Also, the Arizona T220UV printer is equipped with ozone filters located above the fans in the gantry. These filters
ensure that ozone is kept to a minimal safe level.

Arizona T220UV Safety Labels
Introduction
The safety labels are placed at strategic locations on the printer to warn the operator of possible dangers and hazards. It is
important to be aware of the meaning of these labels to ensure safe operation of the printer.
Caution: Read and understand all of the safety label descriptions in the table below before operating the printer.
