Try this:
to reset enter buttons clr, exposure, clr, exposure, the display will blank, enter 14, press prnt button, then clr several times to get out. This may work, if not then you definately need a fuser. Where are you located. Maybe I could send you a used one if this doesnt work.

Sharp AL-800 is blinking H and 4 what could be the problem?

the error code H4, means that an abnormal temperature was detected in the fusing section (the hot roller was not working properly during the initialisation of the printer), to solve the problem;
  1. unplug the printer from the power source
  2. wait for 10 mn
  3. plug the printer again to the power source
  4. switch on the printer
if the error H4 still displayed, you need change the fixing unit, that must be doing by a qualified technician,

Error code H4 flahing on Sharp AL-1000 after power on

That error code is a fuser error. Sometimes it can be reset by a tech, other times you may have to replace a lamp or thermister. Either way you should call your local tech

We had this problem when the power was fluctuating in our building. I called Sharp and they told me to clear this condition with the following code: #*C* and when the screen shows 00-00 enter 14 and press the green copy buton. This worked on the AL-1655CS. On the AL-1631 we had to do a similar thing: C<auto>C<auto> 14 <copy>
