An H4 error code indicates trouble in the fusing section - a certain temperature has not been reached within a specified time. It could mean a dirty/bad thermistor or dirty/bad thermostat (both inside the fuser unit. Make sure both of these are clean and there is not debris/paper stuck inside the unit.
You can try resetting the code by : Get into SIM mode by pressing the following keys one after the other "#" "interupt" "C" "interupt" then enter 14 and the start key - confirm if requested then make sure the copier restarts.
Hope this helps.
