Safety Precaution
2. Safety Against Laser Radiation
As indicated by the Certification and Identification Label attached on the rear cover of the
machine for overseas use, the machine complies with the U.S. Federal Regulations concern-
ing laser safety. The image reader incorporates a laser with a maximum output of 60 mW
(Class 3B, semiconductor laser wavelength of 660 nm, red visible light), but you will not be
exposed to any hazard if you perform tasks as instructed in this manual.
Precautions Against Laser Exposure
Observe the following rules to avoid laser exposure.
Procedures that require precautions against laser exposure
When performing the following procedures, observe the instructions exactly as described in
this manual to avoid laser exposure.
• Remove and restore the scanning optics unit.
• Replace the semiconductor laser unit.
• Replace or clean subscanning unit parts.
After the procedures are completed, put the protective housings and retaining screws back
exactly in their original position to prevent leakage of a laser beam out of the machine.
Preventive maintenance for keeping the machine in compliance
In order to keep the machine in compliance with laser safety standards, perform preventive
maintenance programs described in "Preventive Maintenance Volume" at intervals specified.
Things that should not be done to avoid laser exposure
Observe the following rules during servicing to avoid laser exposure.
• Never attempt to perform procedures other than instructed in this manual because you
may be exposed to laser beam radiation.
• Do not reflect a laser beam by placing a mirror or the like in the laser beam path.
• Do not alter the light path of a laser beam.
• Do not replace optical parts while the laser is energized.
• Never attempt to make optical axis adjustment in the field. Although the semiconductor
laser beam is red visible light, field adjustment of the optical axis cannot be done.
