Handling Toner; Laser Safety - Ricoh RN-MF2 Field Service Manual

• The Controller board on the MF model 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

Handling Toner

• Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid spilling
toner on clothing or the hands.
• If toner is inhaled, immediately gargle with large amounts of cold water and move to a well
ventilated location. If there are signs of irritation or other problems, seek medical attention.
• If toner gets on the skin, wash immediately with soap and cold running water.
• If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are signs of
irritation or other problems, seek medical attention.
• If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there are
signs of any problem, seek medical attention.
• If toner spills on clothing, wash the affected area immediately with soap and cold water. Never use
hot water! Hot water can cause toner to set and permanently stain fabric.
• Always store toner and developer supplies such as toner and developer packages, cartridges, and
bottles (including used toner and empty bottles and cartridges) out of the reach of children.
• Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not
exposed to direct sunlight.
• Do not use the cleaner to suck spilled toner (including used toner). Sucked toner may cause firing
or explosion due to electrical contact flickering inside the cleaner. However, it is possible to use the
cleaner designed for dust explosion-proof purpose. If toner is spilled over the floor, sweep up
spilled toner slowly and clean remainder with wet cloth.

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.
