Explanation : The primary danger in cleaning a fuser assembly is heat. A fuser assembly operates by applying heat to the page, so it becomes very hot. Therefore, you should turn off the computer and let it cool down before cleaning the fuser assembly.
The fuser assembly is located in the printer, not in the computer. It is not necessary to shut down or unplug the computer before cleaning the fuser assembly.
Although you will probably want to unplug the printer cable before cleaning the fuser assembly for convenience, it is not required. A printer is hot swappable, so you do not need to shut down the computer before unplugging the printer cable.
You do not need to attach an Electrostatic Discharge (ESD) strap to the printer casing before cleaning the fuser assembly. The fuser assembly does not include components that would be damaged by ESD.
