The error code E004 deals with the fixing unit. Odds are that you may have one or all of the following parts need to be replaced > the fixing lamps or thermistor or the thermal fuse or the upper fixing roller.... Just for starters... Good Luck

E004-0001 Problem with the Copiers E004-0001 has by fixing Assembly then trimester & film error

This is fixing error, probably bad thermistor. You should check the termistors, lamp, termoswitch.

Here's a link to your support site.

Hope this info helps.

E004 CODE IS FOR FIXING UNIT TEMPERATURE IS NOT REACHED THE SPECIFIED RANGE. CHECK HEATER LAMP, THERMISTER, THERMOSTAT.

A E004 deals with the fuser unit. Have you looked at the Thermister or the thermal fuse or the fixing lamps? I would say that most likely you have a blown or shorted thermister. One of the wires may have come off the pcb.. I you want to see the error code, I believe it is under *6* counters... *4* is for resetting the code

E004 Fixing Unit Failure.
I would recomend calling repair Tech to resolve this issue....unless you know how to access service mode and perform a Printer Reset operation. Could be complete Fuser Unit failure.
