The machine's DC power supply PCB and those of its accessories are equipped with protective functions against excess current and voltage, which will automati-
cally cut off the output voltage in response to an error power condition (caused, for example, by a short-circuit on a load).
If any of these protective mechanism has gone on, turn off the main power switch of the printer unit, and remove the cause of activation; then, leave the machine
alone for about 3 min, and turn its power back on to reset it.
