Hello From The Uk & Happy New Year
Can anyone offer assistance please With A hp FB 950 Error Code

Questions
1. Are They User Replaceable
2. Where Are They Situated Service Side Or Monitor Side & EXACTLY WHEREABOUTS
3. Computer Boots Up Ok But Reports These Error Codes.... No Apparent Reason For Error Codes As The Machine Has Run Pretty Much Faultlessly Since New
I Have Tried To Find A Service Manual That Gives More Info Than The Standard User Guide But To No Avail.
Any Advice Or Thoughts Appreciated
Seasons Greetings & The Best To All My Sign Colleagues Around The World
Thanks Perry

probably you burned the 24-38v power supply,
it is a golden box in electonic box user side.
i replace it with two separate power supply ov 24 and 38v.
you have to watch the amperes.
do you have the technical manual?

FB950 blown fuses

Fuses are self-healing.(no need to replace-not really replaceable anyway) Check circuit for short or over-current condition.

Pointing towards something that is powered by 24 volt has shorted out. If you suddenly have a case fan or a printer fan that is not working. It is likely that is causing this because it has shorted out.

If Electronics boots ok, then it is even more likely a fan, or one of the below, as the printer checks these prior to booting.


Codes also suggesting,
1.bad heater in printhead "jetpack".
2.Possible bad spot in power cable between Ebox and Headboard. Check that power cable-if you have had this printer for several years-as it might have worn through to the wires inside.
3.Anything that runs on 24v. Camera, thermistors, and valves.
