1.6 Safety

1.6.1 Safety of the Laser Light

LBP5050N / LBP5050

Laser beam radiation may pose a danger to the human body. A laser scanner mounted on the machine is sealed with the protection housing and external cover to

prevent the laser beam from leaking to the outside. The laser beam never leaks out of the scanner as far as users operate the machine normally

The following warnings are given to comply with Safety Principles (EN60950).

Laserstrahlen können für den menschlichen Körper gefährlich sein. Aus diesem Grund ist das optische Lasersystem mit einem Schutzgehäuse und einer Außenab-

deckung dicht verschlossen und hat eine Struktur, die keine Laserstrahlen nach außen dringen lässt. Unter der Voraussetzung, dass der Benutzer dieses Gerät normal

bedient, ist ein Austritt von Laserstrahlen daher ausgeschlossen.

1.6.2 CDRH Regulation

LBP5050N / LBP5050

The Center For Devices and Radiological Health (CDRH) of Food and Drug Administration in U.S. has implemented a regulation regarding laser products on Au-

gust 2nd, 1976. This regulation is applied to all products manufactured since August 1st, 1976, and prohibits the sale of laser products without certification.

The following labels certify compliance with the CDRH regulations, and must be attached to all laser products that are sold in the US.

1.6.3 Handling the Laser Unit

LBP5050N / LBP5050

When servicing the area around the laser assembly, be sure to turn off the main power.

If you must servicr while the power is turned on, be sure to keep the followings:

- Do not use a screwdriver or tools that have a high level of reflectance in the laser path.

- Remove watches and rings before starting the work. (They can reflect the laser beam, possibly hitting the eye.)

The machine's covers that can reflect laser light are identified by means of a warning label (Figure). If you must detach a cover showing the label, be sure to take

extra caution during the work.

The following warnings are given to comply with Safety Principles (EN60950).
