Laser Safety - Ricoh D146 Service Manual

Observance of Electrical Safety Standards
The copier and its peripherals must be serviced by a customer service representative who has
completed the training course on those models.
§
Keep the machine away from flammable liquids, gases, and aerosols. A fire or an
explosion might occur.
§
The Controller board on this machine contains a lithium battery. The danger of explosion
exists if a battery of this type is incorrectly replaced. Replace only with the same or an
equivalent type recommended by the manufacturer. Discard batteries in accordance with
the manufacturer's instructions and local regulations.
§
The optional fax and memory expansion units contain lithium batteries, which can
explode if replaced incorrectly. Replace only with the same or an equivalent type
recommended by the manufacturer. Do not recharge or burn the batteries. Used batteries
must be handled in accordance with local regulations.
Safety and Ecological Notes for Disposal
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed
to an open flame.
2. Dispose of used toner, the maintenance unit which includes developer or the organic
photoconductor in accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do not put more than
100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to
chemical reactions and heat build-up.

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.
