Code h4-01 on sharp ar407 had stuck sheet of paper cleared and still have the code.

H4 means the copier (fuser) does not reach a specified temperature within a given time frame.
This means one or more of several things. A bad or dirty thermistor or thermostat (most likely) or a bad heater lamp or a bad control board or AC supply.
The first thing to do is reset the error and see if it comes back. To do this enter service mode by pressing the following keys one after the other (make sure you are in copy mode) "P" "interupt" "C" "interupt" then enter 14 and "start" then enter "1" "start" and accept the reset. Restart the copier. (DONT play around with any other codes)
If problem persists then you may need to remove the fuser unit and take it apart in order to inspect/clean the thermistors and maybe reset/replace the thermostat.
