1-2 Laser Safety Information

CAUTION - Use of controls or adjustments or performance of procedures other than

those specified herein may result in hazardous radiation exposure.

Classification and Labeling of Laser Product

According to the Code of Federal Regulations, laser products are classified in Classes I

through IV. These classes are assigned according to the amount of laser radiation accessible

to the operator. The PantherPro/46 Image Recorder is certified as a Class I product. The

operator is not exposed to any hazardous laser radiation during operation and maintenance.

The laser itself, however, is a Class IIIb laser, and emits laser radiation which is considered

hazardous according to the Federal Code of Regulations, section 1040.10. This level of

radiation is not accessible to the operator as long as the optics cover of the Panther Pro/46 is

not removed.

The PantherPro/46 uses a low-power, 5 milliwatt laser diode which emits visible red light. As

with any bright source of optical energy, safety precautions should be applied. One should

not stare into the beam or any reflections from shiny sources.

Laser Warning Labels

Figure 1-1 represents the laser warning label. This label is located inside the Panther Pro/46

on a protective panel that encloses the laser optics and on the rear panel.

Safety Label

Figure 1-1

Operator Safety

Operator access to laser radiation is not possible during operation or operator maintenance.

During operation the protective housing prevents access to all radiation fields. The recorder

hinged supply cassette cover may safely be opened for operator maintenance. This

maintenance includes removing and installing the photographic media supply and take-up

cassettes.

To insure safety during maintenance, redundant interlocks shut off power to the laser diode

assembly (laser diode power up to 5 milliwatts at 670 nanometers could be accessible in the

machine interior if the interlocks are defeated). The Panther Pro/46 electronics and optics

covers should never be removed by the customer.

Servicing Safety

Service procedures include removal of the machine covers to replace or adjust components.

The inner laser assembly and other components may be replaced in the field. The laser

output and the focused beam are accessible in the interior.

PantherPro/46 Image Recorder TP8251

October 1995 PrePRESS SOLUTIONS CONFIDENTIAL 1-3

The supply cassette cover includes two magnetic interlock switches which are mounted and

connected in series so that if the access door is lifted, both switches open to open the

interlock circuit. When the interlock circuit is open, all power is dropped to the current source

for the laser diode.

All service procedures will be performed with the main power shut off and with the safety

interlock circuit open (no laser diode current).

When performing alignments, carefully follow the procedures documented in the technical

manual. DO NOT defeat the safety interlock switches unless specified in the procedure. Also,

NEVER override the safety interlock switches if the polygon/motor assembly is not spinning,

as this could allow the focused beam to be emitted.

Caution: Direct or indirect reflected eye contact with the laser beam may cause serious

eye damage.

Warning: At no time should the unit be left unattended with the interlocks defeated.

The following safety precautions should always be observed:

1. Never operate the unit with the optics cover removed.

2. Laser safety goggles must be worn when making any adjustments to the recorder with the

interlocks defeated.

3. Any adjustments that are to be made with the interlocks defeated must be made in a

secure area, with only trained personnel present.

4. Do not place screwdrivers or other shiny objects in the path of the laser beam.

5. Remove all jewelry from fingers and wrists before making any alignments.

6. Remember that the laser beam may cause permanent damage to the eyes.

1-3 Regulatory Agencies Information

The PantherPro/46 is an approved product designed and manufactured in accordance with

UL (Underwriters Laboratories) and CSA (Canadian Standards Association) standards. The

product also complies with the requirements in Part 15 of FCC Rules for a Class A computing

device.

This equipment complies with the requirements in part 15 of FCC Rules for a Class A

computing device. Operation of this equipment in a residential area may cause unacceptable

interference to radio and TV reception requiring the operator to take whatever steps are

necessary to correct the interference.

The PantherPro/46 image recorder also complies with specific European safety standards;

International models are shipped with a label bearing the “CE” mark. This label demonstrates

compliance with IEC safety standards. The PantherPro/46 also meets EN55022/VDE Class B

emissions standards.

1-4 Electrostatic Discharge - ESD

Static electricity is, simply, electricity that is not moving. It is harmless as long as it remains

static. Unfortunately, an electrical charge is unstable and is always looking for an opposite

charge to unite with. When a charge moves, it becomes a current, which is often greater than

a electronic circuit can handle.

The smallest static charge that can be felt is 3,000 volts; the smallest charge that can be seen

is 5,000 volts; and the smallest charge that can be heard is 10,000 volts. Some

semiconductor devices are susceptible to a static charge as little as 10 volts.

Electrostatic discharge has become more and more of a hazard as microcircuit components

have become smaller and more sensitive.

ESD Prevention Rules

These are the rules to be learned and followed in order to prevent ESD damage to electronic

printed circuit boards and assemblies.

1. Always use the antistatic portable field service kit when working near exposed electronic

parts or when handling printed circuit boards.

2. Make sure machine is plugged in a grounded outlet (and switched off) if using the

machine frame as a grounding point.

3. Make sure your wrist strap and antistatic service kit are connected together and

connected to ground.

4. When replacing printed circuit boards, remove the old board from the machine before

removing replacement board from the antistatic bag. Then install replacement board and

place old board in the antistatic bag.

5. Always transport and store electronic components in an antistatic bag.

6. Use the correct size bag, not too big or not too small.

7. Keep antistatic bags in good condition. Bags with pin holes, rips, tears, or crumpled bags

are less efficient and may provide little or no protection.

8. Do not remove components from bags just to look at them. You can usually see through

the bag to identify the part.

9. Keep spare bags on hand.

10. Always ship back field returns in an antistatic bag. Even defective components should be

stored and transported in antistatic bags so that they are not damaged further.

11. Keep static producing materials such as polyester, plastic, and Styrofoam away from

electronic parts.

PantherPro/46 Image Recorder TP8251

12. Don’t pick up boards unless you are grounded or the boards are in antistatic bags. Do

not touch edge connectors on PCB’s, or exposed circuitry. Handle IC’s, and boards by

the edges, and never place components on metal surfaces.

13. Static is present at all times, more so when the humidity is low.

14. Educate customers about static protection, especially the ones who maintain their own

equipment.
