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.

What is error code H4


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

HOW TO REDUCE CHANCES OF H4 CODE IN SHARP COPIERS


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.

Zoom H4 Battery Problem


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!

Sharp copier SF-2025 displays an error code H4


H4, not heating up, replace fuser unit complete or work with hivolts and replace an expensive and tricky lamp/thermister . wont be cheap.

. Here use the reset for it first, sometimes power surges can just flip them out but most times will just reappear shortly after reset, indicating the want of a working fuser assembly

Fuser (not fuse) is the hot bit with rollers at paper exit if code fails it needs to be replaced, wont come cheap no matter how you approach it

C-Exposure key-C-Exposure key-14-copy key to clear ... but it will come back I bet...

H4 error code


H4 is a Fuser Unit heating problem.
This reset is for another model sharp, see if it will work for you.

Press "Clear", "Auto Exposuer", "Clear", "Auto Exposure", the display will go dead... then press "14" (Like your going to make 14 copies), then press "Start".

Hope this works.
Good luck,
Mac

Cant get rid of blinking error message, nothing works


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.
