H4 indicates "low temperature", possibly caused by a failure of the heater lamp or fuser. Sometimes this error is shown without an actual damage when the power cord is pulled without shutting down the copier first.
To cancel the error code, press [CLEAR], [AUTO], [CLEAR], [AUTO] in rapid succession. The display should go blank. Next, select 14 (clear low temperature code), press [START]. Finally, switch off and on the machine.
If there was no actual damage (i.e. power cord pulled), the machine should be OK again. If the error persists, immediately or after short time of operation, you will need to contact Sharp technical service for repair.
