0006-0766
The machine's power supply PCB and the power supply PCBs of its accessories are equipped with an overcurrent/
voltage protective mechanisms that prevent damage to the power supply circuit by automatically cutting off the
output voltage in the event of an overcurrent/voltage caused, for example, by a short-circuit in any of its loads.
If the protective function has gone ON, turn off the power switch of the printer unit, disconnect the power plug of
the printer unit or the accessories power supply circuit, and remove the cause of activation; then, leave the machine
alone for about 3 min, and turn it on to reset.
