I have a SHARP MX-3501N.

I received a H4-00 Code. I walked through and cleared the code. After it Power Cycled, I received an H4-30 error. Any advice

The engineers code above worked on our AL-1000 when it started doing an H4 after a power outage. Thanks.

I have a Sharp AL1540CS MFM. It has been displaying the H4 code for a while. Clearing it would work for a time. Removed the fuser assy., and cleaned the temp sensor. It had a wad of toner stuck to it. Cleared the code again, so far so good. Thanks Dan

Thanks Joides, your reply with the engineer reset codes just fixed our "phantom" H4 error after a power failure. I'm sure you saved me tons of time and potentially money :-)

A H4 error means “It is the fuser, but sometimes it is just a false code”, caused by a hiccup in your power supply.

SHARP AL-1642CS Engineers Code for clearing a H4 error (maybe others also)

PRESS: Clear - exposure - clear - exposure = the LED display will turn off.

PRESS: # of copy keys until you have 14 displayed.

PRESS: Enter.

heater lamp error low fuser temp

It is a fuser temperature error or one of the sensors is dirty. You could try removing the fuser assembly - ensure power is switched off- then try cleaning the sensors as they tend to get paper dust and melted toner which collects between the surface which senses the heat from the fuser `Hot` roller. if this does`nt fix it you may need to replace the fuser. There is also an engineer code that you can enter to clear the fault so if you know of a friendly sharp copier engineer....they just might be kind to you !
