4.4 PRECAUTIONS FOR HANDLING THE LASER EQUIPMENT
• 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 printerhead and PC Drum, be sure first to turn the printer OFF.
• If the job requires that the printer 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 tools on the user’s premises.
• The Print Head is not to be disassembled or adjusted in the field. Replace the Unit or
Assembly including the Control Board. Therefore, remove the Laser Diode, and do not
perform Control Board trimmer adjustment.
