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.
Page 10: Caution For Safety
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.
Page 11 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.
Page 12 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.
Page 13: Esd Precautions
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.
