xiv Introduction
Imagesetter Safety Information
Laser Safety
WARNING:
Looking directly into the laser beam or laser beam
reflection can cause permanent eye damage.
The Avantra is a class 1 laser radiation device and is harmless during normal
operation. However, during certain system alignments and tests, the laser is
considered a class 3B device. In this classification, the laser can be harmful to
your eyes.
The laser presents no danger as long as the protective covers are in place.
When the protective covers are removed, follow these safety rules:
• Never look directly into the beam.
• Never expose other persons to the laser beam.
• Use caution with tools and other reflective surfaces to prevent laser reflec-
tion.
• Keep the work area well lit.
• Follow the assembly/disassembly procedures precisely. No short cuts.
These procedures are in the Imagesetter section (Section I), Chapter 4,
“Imagesetter Component Removal/Replacement Procedures”.
• Never operate the laser with the covers removed from the Avantra system.
• Promptly report any actual or suspected accidents. The service engineer
must report immediately to a medical facility if he or she experiences any
of the following eye symptoms:
• A visual halo effect
• A change in tearing (eyes wetter or drier than normal)
• A change in the way colors are seen

• To protect against the hazard of electric shock, do not allow water to run
or spill into the electical compartment or components.
• Before servicing, always disconnect the electric power or unplug the
power cable at the mains.
NOTE:
The OLP has six built-in safety switches, which disconnect
all power whenever the top lids are opened.
• The processor contains a lithium battery.
WARNING:
The battery may explode if mistreated.Do not recharge
or disassemble. Follow local rules for the disposal of lithium batter-
ies.
When handling chemistries, always follow the safety procedures described by the
manufacturers.
Service Manual Audience
This manual is intended for service engineers. It assumes prior knowledge and
experience with the internal workings of an image processor.

before attempting to service the inside of an Avantra 36/44 imagesetter,
processor, bridge, buffer or crane.
NOTE:
The intent of the Removal/Replacement Procedures chap-
ters in this manual are not to repair the units to the level of
their individual components (e.g., the chips on the boards).
They provide instructions for replacing modules (e.g., the
control panel assembly, power supplies, motors, sensors,
etc).

Avantra 36/44 Service Manual
xx Introduction
Product Description
The Avantra 36 and 44 are members of the Avantra family of high-end laser
based PostScript image recorders. They build upon the Avantra 20/25 advanced
capabilities and add new features. The Avantra 36/44 line is especially designed
for users requiring large format output, such as packaging and posters. Both
systems support the high quality imaging requirements needed for CristalRaster.
Standard Equipment
The Avantra contains the following standard equipment:
• Punch system
• head and tail
• Stoesser, Bacher, or Bacher Plate
• Multiple media supply capability
• allows two different (or same) media to be on line within the engine at
the same time
• Flex media
• automatically adjusts focus for the selected media thickness
• user-definable media widths
Advanced Features
In addition to the advanced design features of the 20/25, the 36/44 has:
• EasyLoad media handling, which allows the convenient loading of large
format supply cassettes.
• Vacuum system, which aids in keeping the media tight against the drum for
optimum image quality.
• Integrated on-line processor with bridge/buffer/crane (optional).
Options
Options include:
• On-line bridge buffer
• bridge is contained within the engine
• buffer is a separate unit attached to the back of the imagesetter, which
allows a full page to be buffered while imaging the next page
• crane for loading and unloading off-line cassettes
• standard cassette can be easily used if a problem with the bridge/
buffer is encountered
• Custom punches
• Easyload media handling cart
