You can print your Parts List or export to Excel to further work with it. We only help you to create your parts list for request from your suppliers. Add your headers and comments. Use saved Parts Lists as templates to create new lists. Change the contents of the old list and save it as new. You can add, delete list items, change headers, comments and quantity of spare parts. Depending on the model, some of the precautions given in the following do not apply. Different markings are used to denote specific meanings as detailed below.

The following graphic symbols are used to give instructions that need to be observed. Used to call the service technician attention to what is graphically represented inside the marking (including a warning). Used to prohibit the service technician from doing what is graphically represented inside the marking. Used to instruct the service technician to do what is graphically represented inside the marking. 1-1. Warning WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. WARNING1. 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 Operators Manual. 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. Do not throw toner or the toner bottle into a fire. Do not throw toner or the Toner Bottle (Imaging Cartridge, Toner Cartridge) into a fire. Toner expelled from the fire may cause burns. 4. Use the specified parts. For replacement parts, always use the genuine parts specified in the manufac-turers parts manual. Installing a wrong or unauthorized part could cause dielectric breakdown, overload, or undermine safety devices resulting in possi-ble electric shock or fire. Replace a blown electrical fuse or thermal fuse with its corresponding genuine part specified in the manufacturers 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. 5. 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 con-nected. Be sure the power outlet meets or exceeds the specified capacity. Use only the power cord supplied in the package. If a power cord is not sup- plied, only use the power cord and plug that is specified in POWER CORD INSTRUCTION. Failure to use this cord could result in a fire or electrical shock. Use the power cord supplied in the package only for this machine and NEVER use it for any other product. Failure to observe this precaution could result in a fire or electrical shock. 6. Be careful with the high-voltage parts. A part marked with the symbol shown on the left carries a high voltage. Touch-ing 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. 7. 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. 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 ener-gized. Touching them may result in a burn. Wait until these parts have cooled down before replacing them or any sur-rounding parts. 9. Maintain a grounded connection at all times. Connect the power cord to an electrical outlet that is equipped with a grounding terminal. 10. 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. 11. 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. CAUTION1. Precautions for Service Jobs. A star washer and spring washer, if used originally, must be reinstalled. Omit-ting 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 mal-function, 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. 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 manufac-turers parts manual. Before installing a new battery, make sure of the correct polarity of the installa-tion or the battery could burst. Dispose of used batteries according to the local regulations. Never dispose of them at the users premises or attempt to try to discharge one. 5. Precautions for the Laser Beam. (Only for Products Employing a Laser) Removing the cover marked with the caution label could lead to possible expo-sure 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. Make sure that no one enters the room when the machine is in this condition. When handling the laser unit, observe the Precautions for Handling Laser Equipment. 6. Precautions for storing the toner or imaging cartridge. Be sure to keep the toner or imaging cartridge out of the reach of children.

Licking the imaging cartridge or ingesting its contents is harmful to your health. Discover everything Scribd has to offer, including books and audiobooks from major publishers.
