Power supply
Ensure yourself ...
that the ratings of the power supply match the ratings shown on
the back of the printer. If in doubt, ask your supplier;
that the printer is connected to an earthed mains socket with the
cable supplied;
when using an extension cable or multiple socket that you do
not exceed the maximum electrical load for this;
all reasonable precautions have been taken to prevent damage
to the power cable. Do not place objects on the cable and make
sure it is routed so that nobody walks on it or trips over it;
that a damaged cable is replaced immediately;
before cleaning the printer or the case, that the power cable is
removed from the power supply. Use only a clean cloth for
cleaning. Do not use liquids or aerosol cleaners;
you have removed the plug from the mains outlet to ensure
complete isolation from the mains supply. The mains outlet you
are using must be located close to the printer and be easily
accessible.
The three wires of the power cable are colour coded. The earth wire
is yellow-green, the neutral wire is blue and the live current is on
the brown wire.
