Although modern printers now include many safety interlocks and protection circuits, it is still possible for a high voltage or a residual voltage to be present on the various rollers, wires, and metal contacts inside a laser printer. It is important that care should be taken to avoid unnecessary contact with these parts to reduce the potential for painful electrical shock.

Most importantly, unplug the printer first. Do not perform any service or maintenance on an equipment that is plugged in. Printers can also have very hot surfaces (used to melt the print media into the paper) so there is a possibility for burns, so let the equipment cool for at least an hour or so before opening it up.

Another thing is to remember to close everything up before plugging the equipment back in. Never assume equipment is de-energized just because you turned an on/off switch to the off position. Most electrical equipment nowadays uses some power even when turned off.
