Precautions 1. Precautions In order to prevent accidents and to prevent damage to the equipment please read the precautions listed below carefully before servicing the printer and follow them closely. 1.1 Safety Warning (1) Only to be serviced by appropriately qualified service engineers. High voltages and lasers inside this product are dangerous. This printer should only be serviced by a suitably trained and qualified service engineer.
Precautions 1.2 Caution for safety 1.2.1 Toxic material This product contains toxic materials that could cause illness if ingested. (1) If the LCD control panel is damaged it is possible for the liquid inside to leak. This liquid is toxic. Contact with the skin should be avoided, wash any splashes from eyes or skin immediately and contact your doctor. If the liquid gets into the mouth or is swallowed see a doctor immediately. (2) Please keep Drum cartridge and Toner Cartridge away from children.
Precautions 1.2.3 Handling Precautions The following instructions are for your own personal safety, to avoid injury and so as not to damage the printer (1) Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause the printer to tip or fall. (2) The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your fingers, hair or clothing in any of these rotating devices.
Precautions 1.2.5 Disregarding this warning may cause bodily injury (1) Be careful with the high temperature part. The fuser unit works at a high temperature. Use caution when working on the printer. Wait for the fuser to cool down before disassembly. (2) Do not put finger or hair into the rotating parts. When operating a printer, do not put hand or hair into the rotating parts (Paper feeding entrance, motor, fan, etc.). If do, you can get harm.
Precautions 1.3 ESD Precautions Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called “Electrostatically Sensitive (ES) Devices” or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

Disassembly and Reassembly 3. Disassembly and Reassembly 3.1 Precautions when replacing parts 3.1.1 Precautions when assembling and disassembling * Use only approved Samsung spare parts. Ensure that part number, product name, any voltage, current or temperature rating are correct. Failure to do so could result in damage to the machine, circuit overload, re or electric shock.
Disassembly and Reassembly 3.2 Parts for Maintenance and Repair 3.2.1 Replacement interval for parts with a limited life Some of the parts in this printer have a limited life, shorter than that of the whole machine. These parts must be replaced periodically. The table below shows the interval at which these parts should be replaced. The table shows the life of each part, and is measured when using A4 paper.
Disassembly and Reassembly 3.2.2 Printer Cleaning A printer should be regularly cleaned, especially if it is used in a dusty environment. This will ensure that print quality remains high and failure due to contamination of printing services is less likely to occur. * Clean the printer with a soft, lint free, cloth dipped in a “Recommended cleaner” “Recommended cleaner” can be purchased from our service center. (where available) * Do not touch the transfer roller when cleaning the inside of the printer.
Disassembly and Reassembly 3.3 Information Related to Disassembly and Assembly. 3.3.1 Special service parts Never disassemble or adjust the items mentioned, a stock of these items should be maintained. 1) Disassembly of the LSU unit 4) Disassembly of DEVE drive ass’y and the main drive ass’y There are no serviceable parts inside the LSU. Alignment of the mirrors is critical. Opening the LSU will allow dust into the laser and signi cantly reduce print quality.
Disassembly and Reassembly 3.3.2 Screws used in the printer The screws listed in the table below are used in this printer. Please ensure that, when you disassemble the printer, you keep a note of which screw is used for which part and that, when reassembling the printer, the correct screws are used in the appropriate places.
