WARNING:
High voltages are present inside the printer when the power is
on. Do not attempt to remove the controller board unless the
printer is turned off and the power cord is unplugged. Also,
try not to touch the contacts on the board because many
of the
components can be destroyed by the static electricity in your
body.
