WARNING
1.Always observe precautions.
•Parts requiring special attention in this product will include a label containing the mark shown on the left plus precautionary notes. Be sure to observe the precautions.
•Be sure to observe the “Safety Information” given in the Operator’s Manual.
2.Before starting the procedures, be sure to unplug the power cord.
•This product contains a high-voltage unit and a circuit with a large current capacity that may cause an electric shock or burn.
•The product also contains parts that can jerk suddenly and cause injury.
•If this product uses a laser, laser beam leakage may cause eye damage or blindness.
3.Use the specified parts.
•For replacement parts, always use the genuine parts specified in the manufacturer’s parts manual. Installing a wrong or unauthorized part could cause dielectric breakdown, overload, or undermine safety devices resulting in possible electric shock or fire.
•Replace a blown electrical fuse or thermal fuse with its corresponding genuine part specified in the manufacturer’s parts manual. Installing a fuse of a different make or rating could lead to a possible fire. If a thermal fuse blows frequently, the temperature control system may have a problem and action must be taken to eliminate the cause of the problem.
P-1
4.Handle the power cord with care and never use a multiple outlet.
•Do not break, crush or otherwise damage the power cord. Placing a heavy object on the power cord, or pulling or bending it may damage it, resulting in a possible fire or electric shock.
•Do not use a multiple outlet to which any other appliance or machine is connected.
•Be sure the power outlet meets or exceeds the specified capacity.
5.Be careful with the high-voltage parts.
•A part marked with the symbol shown on the left carries a high voltage. Touching it could result in an electric shock or burn. Be sure to unplug the power cord before servicing this part or the parts near it.
6.Do not work with wet hands.
•Do not unplug or plug in the power cord, or perform any kind of service or inspection with wet hands. Doing so could result in an electric shock.
7.Do not touch a high-temperature part.
•A part marked with the symbol shown on the left and other parts such as the exposure lamp and fusing roller can be very hot while the machine is energized. Touching them may result in a burn.
•Wait until these parts have cooled down before replacing them or any surrounding parts.
8.Maintain a grounded connection at all times. (This item may not apply in the USA.)
•Be sure to connect the ground wire to the ground terminal even when performing an inspection or repair. Without proper grounding, electrical leakage could result in an electric shock or fire.
•Never connect the ground wire to a gas pipe, water pipe, telephone ground wire, or a lightning conductor.
9.Do not remodel the product.
•Modifying this product in a manner not authorized by the manufacturer may result in a fire or electric shock. If this product uses a laser, laser beam leakage may cause eye damage or blindness.
10.Restore all parts and harnesses to their original positions.
•To promote safety and prevent product damage, make sure the harnesses are returned to their original positions and properly secured in their clamps and saddles in order to avoid hot parts, high-voltage parts, sharp edges, or being crushed.
•To promote safety, make sure that all tubing and other insulating materials are returned to their original positions. Make sure that floating components mounted on the circuit boards are at their correct distance and position off the boards.
P-2
CAUTION
1.Precautions for Service Jobs
•A toothed washer and spring washer, if used originally, must be reinstalled. Omitting them may result in contact failure which could cause an electric shock or fire.
•When reassembling parts, make sure that the correct screws (size, type) are used in the correct places. Using the wrong screw could lead to stripped threads, poorly secured parts, poor insulating or grounding, and result in a malfunction, electric shock or injury.
•Take great care to avoid personal injury from possible burrs and sharp edges on the parts, frames and chassis of the product.
•When moving the product or removing an option, use care not to injure your back or allow your hands to be caught in mechanisms.
2.Precautions for Servicing with Covers and Parts Removed
•Wherever feasible, keep all parts and covers mounted when energizing the product.
•If energizing the product with a cover removed is absolutely unavoidable, do not touch any exposed live parts and use care not to allow your clothing to be caught in the moving parts. Never leave a product in this condition unattended.
•Never place disassembled parts or a container of liquid on the product. Parts falling into, or the liquid spilling inside, the mechanism could result in an electric shock or fire.
•Never use a flammable spray near the product. This could result in a fire.
•Make sure the power cord is unplugged before removing or installing circuit boards or plugging in or unplugging connectors.
•Always use the interlock switch actuating jig to actuate an interlock switch when a cover is opened or removed. The use of folded paper or some other object may damage the interlock switch mechanism, possibly resulting in an electric shock, injury or blindness.
3.Precautions for the Working Environment
•The product must be placed on a flat, level surface that is stable and secure.
•Never place this product or its parts on an unsteady or tilting workbench when servicing.
•Provide good ventilation at regular intervals if a service job must be done in a confined space for a long period of time.
•Avoid dusty locations and places exposed to oil or steam.
•Avoid working positions that may block the ventilation ports of the product.
4.Precautions for Handling Batteries (Lithium, Nickel-Cadmium, etc.)
•Replace a rundown battery with the same type as specified in the manufacturer’s parts manual.
•Before installing a new battery, make sure of the correct polarity of the installation or the battery could burst.
•Dispose of used batteries according to the local regulations. Never dispose of them at the user’s premises or attempt to try to discharge one.
P-3
5.Precautions for the Laser Beam (Only for Products Employing a Laser)
•Removing the cover marked with the following caution label could lead to possible exposure to the laser beam, resulting in eye damage or blindness. Be sure to unplug the power cord before removing this cover.
•If removing this cover while the power is ON is unavoidable, be sure to wear protective laser goggles that meet specifications.

Other Precautions
•To reassemble the product, reverse the order of disassembly unless otherwise specified.
•While the product is energized, do not unplug or plug connectors into the circuit boards or harnesses.
•The magnet roller generates a strong magnetic field. Do not bring it near a watch, floppy disk, magnetic card, or CRT tube.
•An air gun and vacuum cleaner generates a strong electrostatic charge that can destroy the ATDC sensor and other sensors. Before cleaning a component with one of these devices, be sure to remove all the sensors. Otherwise, use a blower brush and cloth when cleaning parts.
•When handling circuit boards with MOS ICs, observe the “INSTRUCTIONS FOR HANDLING THE PWBs WITH MOS ICs” (applicable only to the products using MOS ICs).
•The PC Drum is a very delicate component. Observe the precautions given in “HANDLING OF THE PC DRUM” because mishandling may result in serious image problems.
•Note that replacement of a circuit board may call for readjustments or resetting of particular items, or software installation.
•After completing a service job, perform a safety check. Make sure that all parts, wiring and screws are returned to their original positions.
•Check the area surrounding the service site for any signs of damage, wear or need of repair.
•Do not pull out the toner hopper while the toner bottle is turning. This could result in a damaged hopper motor or locking mechanism.
