Replace the thermistor in the fuser unit.

At the exit there is a unit with two big rollerrs, this is the Fuser unit there is a sensor there that regulates the temperature, it is bad, replace and it should be OK, not sure if you have to clear the code internally.

While starting the xerox machine SHARP AR 5316 , indicator is showing 4 and blinking everytime, unable to take the printout

I'm going to guess that if you watch the display closely, it is alternating between an "H", and a "4". If that is the case, you have an "H4" error code. This is a fuser error and can either be a freak out from the machine, or an indication of something serious. I would recommend resetting the code and seeing if it comes back. To reset the code, turn the machine on and press "#" -> "Interrupt" -> "Clear" -> "Interrupt". Doing this should put you into service mode, where the display will show a blinking double dash (--). Enter 14 and press the green start button, just like you are trying to make 14 copies of something. At this point, the machine should restart itself and hopefully the error code will go away. If the error code does not go away, or recurs on a fairly frequent basis, I would recommend contacting a professional service technician.
