Ricoh P C300W Field Service Manual page 7

Laser Safety
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units
in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite
equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser
chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and
laser subsystems to the factory or service depot when replacement of the optical subsystem is required.
•
Use of controls, or adjustment, or performance of procedures other than those specified in this
manual may result in hazardous radiation exposure.
WARNING FOR LASER UNIT
WARNING:
Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser
beams can seriously damage your eyes.

Batteries
Always replace a battery with the same type of battery prescribed for use with the color controller unit.
Replacing a battery with any type other than the one prescribed for use could cause an explosion.

Never discard used batteries by mixing them with other batteries or other refuse.

Always remove used batteries from the work site and dispose of them in accordance with local
laws and regulations regarding the disposal of such items.
