My Sharp AL1530cs photocopier having error message/code H4 and how can I reset the machine?

SOURCE: SHARP AR-M277

this should resolve it.

NOTE: Some Status codes will not clear even though the problem has been fixed. Status codes that will not clear must be manually reset using the 'Fault Reset 14 Procedure'.

1. Locate the [C] (Clear) button on the Control Panel, at the far right.
2. Locate the Image Quality button, below the Auto on the Control Panel, toward the left side.
3. Press the buttons in the following sequence within 4 seconds. Press [C] (Clear), press [Image Quality], press [C] (Clear) again, press [Image Quality] again.
4. The error code should disappear. If the Status code does not clear, repeat step 3 until the status code clears; but no more than five times.
5. Use the [10] and [1] buttons to enter 14 on the Display Screen, as if you were to make 14 copies.
6. Press the [Start] button. The machine should be ready to use.
7. Make a copy, to check that the machine is working properly.

Performing a Fault Reset 14 will reset your WorkCentre and will help to clear error codes.

1. Find the pink Clear button on the Control Panel of the WorkCentre.
2. Find the button below the word Auto.
3. Press these buttons in the following sequence: [Clear], [Auto], [Clear], [Auto] NOTE: All of the lights on the Control Panel should go out and the LED Display should go blank. If the lights do not go out, then repeat step 3 until they do. It may be necessary to increase or decrease the pace of the [Clear], [Auto], [Clear], [Auto] sequence.
   
4. Press the [10's] key one time and the [1's] key four times to enter '14' in the LED Display, as if you were to make 14 copies.
5. Press the green [Start] button.
6. Press the pink [Clear] button two times.
7. The WorkCentre should now warm up and come to ready.
8. If the above steps do not clear the error code, repeat steps 3 to 6 a second time.

H4-00 means heat roller low temperature detection. It usuallly caused by 3 things :

1. The machine hang : You simply reset the error code by pressing : # * C * then input 14 then start.
2. If the error still displayed, open the side cover, feel the fusing unit ( don't touch, it is hot ), if the
fusing unit feels cold then the problem is the heater lamp ( inside the upper heater roller,
connected with anti heat cable and big connector ), you should replace it.
3. If the fusing unit feels warm or hot then the problem is the thermistor ( connected with small cable
and connector ), replace it.
