It happened only when our generator failed to continously working and it happened to turn on and off. before the last power shut-off i made a few copies from it and when the last power off this "H4" code blink on. please help on this. what does it mean? ive heard that some codes can be reseted, please if there is any what it is?

Re: H4 error code
H4 codes are related to the fusing unit. Specifically a low heat condition. Follow the reset procedure below. If that doesn't work further diagnosis of the fusing unit an peripherial circuits may be warranted.
Error code reset:
Perform the following key procedure "#" key, Interrupt key, "C" key, Interrupt key
"1" key, "4"key
Start key, "CA" key.
See if unit cycles and comes back up. If not turn off and then back on the main power. If error reappears on site technical service may be required.

Hi don the error code is a system overload. There are a lot of things that could be causing this temperature short circuit. Inwould take the cover of the unit and see if you can visually see any maybe dust or debri on any condenser coils or fans. If you can't figure it out call an expert.
Here is a link to the manual for your system
The code H4 is common to all Sharp copiers. This occurs due to abnormal low temperature being sensed by thermistor. This means that the heater lamp which generates heat around the fuser rollers is either not working or producing very low heat. Low heat generated comes from low power output in the mains so, when you suspect low voltage, always switch off your copier and wait for normalcy. You can see from dim bulbs and know that's low voltage.
I am having the same problem with my Zoom-H2. I have 2 2650 mah rechargeables, and the draw is such that 20-30 minutes of record &/or playback kills the batteries. Last night I just turned the power on and did nothing. 5 hours later the batteries were dead...
This isn't a solution. It is a reaffirmation that you aren't crazy!
You shut the machine off then on, Press Clear, auto,clear , auto, then when the lights go out, program it as if you were running 14 copies. press start and that should reset it.
Thats the redish pink clear button and the auto exposure button, Clear, Auto , clear auto, and the display goes blank , enter 14 and start. Dont ask me why I repeated that LOL
The correct buttons to push in order to get into the service mode on a 162D are [#] key, [*] key, [C] key and [*] key. Then you key in 14 - 00 and press the Start key. If that fails to bring your machine back on, you'll have to replace the fusing assembly.
