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 fingers 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 so, you may get harm.
3. When you move the printer.
This printer weighs 17.8kg including the toner cartridge and cassette. Use safe lifting

Failure to do so could cause the printer to tip or fall, possibly causing personal injury or
damaging the printer.
5. Do not install the printer on a sloping or unstable surface.
After installation, double check that the printer is stable.
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.
ƒ Be sure that no power is applied to the chassis or circuit, and observe all other
safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped
