SAFETY INFORMATION
This printer is a page printer which operates by means of a laser. There is no possibility of danger from
the laser, provided the printer is operated according to the instructions in this manual provided.
Since radiation emitted by the laser is completely coti-ined within protective housings, the laser beam
camot escape from the machine during any phase of user operation.
For United States Users:
[Laser Safety]
This printer is certified as a Class 1 Laser product under the U.S. Department of Health
and Human Services (DHHS) Radiation Performance Standard according to the Radia-
tion Control for Health and Safety Act of 1968. This means that the printer does not
produce hazardous laser radiation.
[CDRH Regulations]
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration implemented regulations for laser products on August 2,1976. Compli-
ance is mandatory for products marketed in the United States. The label shown below
indicates compliance with the CDRH regulations and must be attached to laser products
marketed in the United States.
`WARNING: Use of controls, adjustments or performance of procedures other
than those specified in this manual may result in hazardous radiation exposure.
[Internal Laser Radiation]
Maximum Radiation Power: 5.7 x 104 (w)
Wave Length: 780 nm
This is a Class IIIb Laser Diode Assay that has an invisible laser beam. The print head
unit is NOT A FIELD SERVICE ITEM. Therefore, the print head unit should not be
opened under any circumstances.
For Other Countries Users;
wARNING: Use of controls, adjustments or performance of procedures other
than those specified in this manual maY result in hazardous radiation exposurel
?his is a semiconductor laser. The maximum power of the laser diode is 5.7 x
10-4 W and the wavelen @h is 780 nm.
