Temperature error, use simulation mode 14 for reset the error , if not replace the thermistor, & use stabilizer to avoid problems due to power fluctuations.
SOURCE: Sharp ar-c330 with an error code of H4-01. Any
yes your copier is problem fuser uniter
such as heater lamp or thermostator burning
SOURCE: Sharp AR-M450 is showing error code ''H4-00''
You're getting a heat roller low temp detection on the fuser in your copier. The fuser is the device that provides heat and pressure to the toner to bond/fuse it to the paper (it's that black, rectangular box in the upper part of the body when you open the left-hand side of the door).
Chances are a peice of paper is jammed up inside and blocking the sensor (probably a small peice that tore from a page someone tried to pull from the fuser). That or the temp sensor is defective.

This means that the fusing unit has a problem. Turn off the copier. Open the small side cover on the right of the fuser unit. You will see the wire connectors leading from the unit and carefully remove them.Open the three screws holding the unit and remove it, check the heater lamp continuity if out replace the lamp. Clean the thermistor and return the unit by reversing the removing process. Now try the code and it will work.
