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 acces-

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

operator is not exposed to any hazardous laser radiation during operation and mainte-

nance.

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 PantherPro is

not removed.

The PantherPro uses a low-power, 5 milliwatts laser diode which only 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 PantherPro on

a protective panel that encloses the laser optics, on the rear panel, and the electronics

cover. (See Figure 1-2).

CAUTION - LASER RADIATION WHEN OPEN.

AVOID DIRECT EXPOSURE TO BEAM.

Operator Safety

Operator access to laser radiation is not possible during operation or operator mainte-

nance. 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 PantherPro 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 compo-

nents. 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.

The supply cassette door 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 is invisible and can cause permanent damage to the

eyes.

1-3 Regulatory Agencies Information

The PantherPro 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 comput-

ing 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 unaccept-

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

are necessary to correct the interference.

The PantherPro also complies with specific European safety standards; international mod-

els are shipped with a label bearing the “CE” mark. This label demonstrates compliance

with IEC safety standards. The PantherPro 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

1-5November 1994 PrePRESS SOLUTIONS CONFIDENTIAL

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

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

Electrostatic discharge has become more and more of a hazard as microcircuit compo-

nents 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 elec-

tronic printed circuit boards and assemblies.

WARNING: Make sure you are NOT grounded when working on equipment that is

plugged in and ON.

1. Always use the antistatic portable field service kit when working on electronic parts of

PrePRESS Solution’s products or when handling printed circuit boards.

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

chine frame as a grounding point.

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

nected 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 elec-

tronic parts.

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
