Re: Sharp SF-1118 copying machine H 4 Error
Open right side door and check for a jam in the fusing unit (the one that is normally hot). Remove jam carefully. Hit P * C * and enter 14. Push the start button like you are making a copy. Machine should reboot and code should not return. if it does, you may have a dirty themistor, or blown lamp.

This is a heating error for the fusing section, the lamps may be damaged or there could be a build up of dust and debris on the thermistors that monitor temperature. I would check the fusing section. THIS IS THE UNIT THAT HAS THE TWO ROLLERS THAT THE PAPER PASSES THROUGH AT THE END OF THE PAPER PATH. Check there is nothing jammed or damaged. you may need to replace unit.
I found this on another website and it worked for me. It apparently resets the printer. Hope it works for you:
1.) power on (error message) 2.) press the "Stop (triangle)" and the "Colour copy" button and hold them 3.) press the power button to power off, still hold 2.) 4.) press the power button to power on, still holding 2.) 5.) the LEDs start to flash, then they stop to flash and the red exclamation mark starts to flash. Now release 2.)
6.) the LED should say: "Init EEprom" 7.) now press and hold the power button until the printer powers off and powers on again.
Find the pink Clear button on the Control Panel of the WorkCentre.
Find the button below the word Auto.
Press these buttons in the following sequence: [Clear], [Auto], [Clear], [Auto]
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.
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.
Press the green [Start] button.
Press the pink [Clear] button two times.
The WorkCentre should now warm up and come to ready.
If the above steps do not clear the error code, repeat steps 3 to 6 a second time.
OK, CH normally means the one of the covers(front or side panels) is open or the developer unit is unplugged try these to see if that fixes the problem.
When the covers are closed a small tab on the covers triger a interlock switch or optical switch.
Hope this helps
