Laser Safety - Ricoh Aficio SP C440DN Field Service Manual

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: Turn off the main switch before attempting any of the procedures in the Laser Optics
Housing Unit section. Laser beams can seriously damage your eyes.
• CAUTION MARKING:
