Code H4 comes up when the sharp copier ar-5316 is switched on. it cannot be use. what shall I do to solve this problem of error code H4.

H4 normally is the problem with the fuse unit caused by thermistors or therm-state charge them then clean it by sim 14 but first check if the connector and fame then do sim 5-02 to check the lamp status

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.

H4-00 Heat roller low temperature detection

For H4 enter the following codes # interrupt C interrupt 14 Start button twice For ch check whether all the doors(side door,front door) are closed.
