PRECAUTIONS FOR HANDLING THE LASER EQUIPMENT

• The laser used in this copier is a semiconductor laser with the following specifications:
• When laser protective goggles are to be used, select ones with a lens conforming to the
above specifications.
• When a disassembly job needs to be performed in the laser beam path, such as when
working around the PH and PC Drum, be sure to turn the copier OFF first.
• If the job requires that the copier be left ON, take off your watch and ring and wear laser
protective goggles.
• A highly reflective tool can be dangerous if it is brought into the laser beam path. Use
utmost care when handling such tools near the laser.
• The PH is not maintainable in the field. It is to be replaced as a unit including the control
board. Never, therefore, attempt to remove the laser diode or adjust trimmers on the con-
trol board.
