When operating a printer. The fuser unit works at a high temperature. If do. After installation. Wait for the fuser to cool down before disassembly. Failure to do so could cause the printer to tip or fall possibly causing personal injury or damaging the printer. Back injury could be caused if you do not lift carefully. Do not remove a replacement ESD from its protective packaging until immediately before installing it.
Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions. Examples of typical ESDs are: After removing an electrical assembly equipped with ESDs. Super capacitor or Lithium batteries contain toxic substances and should not be opened. Use only a grounded tip soldering iron to solder or desolder ESDs. When sprayed. Immediately before handling a semiconductor component or semiconductor-equipped assembly. Exercise caution when replacing a super capacitor or Lithium battery.
Be sure to replace the battery with the same or equivalent type recommended by the manufacturer. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed.
The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity. Most replacement ESDs are packaged with all leads shorted together by conductive foam. Immediately before removing the protective shorting material from the leads of a replacement ESD.
Do not use Freon-propelled chemicals. For general home use. Reference Information 11 Reference Information This chapter describes the reference information for applying this training manual.
