The fuse protects your printer from short circuits and power overload. It is placed between the power outlet and the switch on the left side of the printer. If your machine does not start after pressing the power switch, at first you should check if the power cable is connected to a power source. Then, you should check if the LED on the power supply unit is on. If the diode is lit, the fuse is probably blown and needs to be replaced. Follow the instructions provided in this manual to see the correct replacement procedure.
