SAFETY AND IMPORTANT WARNING ITEMS WARNING: Safety Checkpoints • After replacing a part to which AC voltage is applied (e.g., optical lamp and fixing lamp), be sure to check the installation state. A risk of fire exists. • Check the interlock switch and actuator for loosening and check whether the interlock functions properly. If the interlock does not function, you may receive an electric shock or be injured when you insert your hand in the MFP (e.g., for clearing paper jam). • Make sure the wiring cannot come into contact with sharp edges, burrs, or other pointed parts. Current can leak, leading to a risk of electric shock or fire. • Make sure that all screws, components, wiring, connectors, etc. that were removed for safety check and maintenance have been reinstalled in the original location. (Pay special attention to forgotten connectors, pinched cables, forgotten screws, etc.) A risk of MFP trouble, electric shock, and fire exists. DANGER: HANDLING OF SERVICE MATERIALS • Toner and developer are not harmful substances, but care must be taken not to breathe excessive amounts or let the substances come into contact with eyes, etc. It may be stimulative. If the substances get in the eye, rinse with plenty of water immediately. When symptoms are noticeable, consult a physician. • Never throw the used cartridge and toner into fire.
