The H4 means "Heat roller low temperature detection"
Basically the fuser is not reaching a specified temp within a specified time frame. There are several causes/posibilities :
Heater lamp abnormality
Control Board PWB abnormality
or it is just a one glitch and it can be reset.If re-seting the copier does not work then it could be something physically wrong.
To clear error go into SIM mode by pressing the following keys one after the other "#" "interupt" "C" "interupt" (must be in copy mode to start off). enter 14 and start key. Confirm if requested to do so. copier must be restarted when this is done. Do not play around with any other settings in SIM mode.
If error persists then one of the above items is at fault. you could pull out the fuser unit and open it up to check for any dirt/debris buildup around the thermistors/thermostat.
Hope this will help.
