The code H4 is common to all Sharp copiers. This occurs due to abnormal low temperature being sensed by thermistor. This means that the heater lamp which generates heat around the fuser rollers is either not working or producing very low heat. Low heat generated comes from low power output in the mains so, when you suspect low voltage, always switch off your copier and wait for normalcy. You can see from dim bulbs and know that's low voltage.

H4-00 on Sharp means that the temperature inside the printer is too low. That is usually the fuser lamp, and rarely the temp sensor.
When this happen you need to have the fuser unit replaced, if that does not fix the problem the technician will replace the temperature sensor.
