Releasing Plastic Latches
Many of the parts are held in place with plastic latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the latch away from the part to which it is latched.

Disregarding this warning may cause bodily injury
1. The fuser unit works at a high temperature. Use caution when working on the machine. Wait
for the fuser to cool down before disassembly.
2. Do not put fingers or hair into the rotating parts (paper feeding entrance, motor, fan, etc.).
Doing so may cause injury.
3. When you move the machine.
This machine weighs 12kg (26.7lb) including packaging. Use safe lifting and handling tech-
niques. Back injury could be caused if you do not lift carefully.
4. Ensure the machine is installed safely.
The machine weighs 9.7kg (21.4lb) including toner cartridge, ensure the machine is installed
on a level surface, capable of supporting its weight. Failure to do so could cause the machine
to tip or fall possibly causing personal injury or damaging the machine.
5. Do not install the machine on a sloping or unstable surface. After installation, double check
that the machine 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.
CAUTION
Be sure 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
assembly, drain off any electrostatic charge on your body by touching a known earth ground.
Alternatively, employ a commercially available wrist strap device, which should be removed
for your personal safety reasons prior to applying power to the unit under test.
