I'M guessing that you have a Sharp copier? A H4-00 is a fuser error code. You may be able to reset it? There are a few different ways to get into service mode, but I don't know the model you have. Good Luck

There are 2 possible causes for this error - both closely related. H4-00 means the fusing temperature is not reached within a specified time. You can check and clean/replace the thermistors in the fuser unit, check the thermostat aswell. If thermostat rattles it is good otherwise press the reset button it. If everything checks ok reset the fuser code in service mode pressing the following keys :
P * C * then enter 14 and start then confirm action and restart copier. If error comes back then it could be related to the wiring harness to the PCU board (loose connector) or possibly a bad lamp. Check the lamps with a meter set to check continuity (you should get a beep if its working)

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.
