While drum unit and scanner window cleaning basically can be implemented by the end user,
the electrical terminals inside the machine and on the drum unit should be cleaned by a
service technician. Instruct the users not to touch those terminals.
There are high voltage electrodes inside the machine. Before cleaning the machine,
make sure that the power switch has been turned off and the power cord has been
unplugged from the power outlet.
