Did you try a different outlet?

Remove the Hard Drive (if you have one installed), network card (if it's not embedded in the board), and any other optional equipment (sorter stacker, additional feeder trays, etc...). Power it up and see if it is good. If it is, power the machine off and add one of the options you removed. Then, power it up again. Repeat with each optional component. When you start having problems again, remove the last part installed as that will be the defective part.

Do you hear any fans running? I am guessing it wont print an engine test?

Usually if there are no fans and it's completely dead, it's the LVPS. But you said you've changed that. There are 2 power supplies in this machine, BTW. The reason I mentioned the other opt. equipmnt. is sometimes a short in one of them can cause power issues.

Thanks Guys

Well yes i changed the outlet , power cord and all the others components that i could.(trays,duplex,formatter,adf) and i cant see or hear any fan running. Hp sended hight voltage, low voltage and dc controller that i changeg but the printers dosnt work and i recall Hp to have support and they just say probably Low voltage was DOA then send a new one but last night i chenged and nothing happend.
i want to ask the 3 parts at same time and change it in one shoot because for me something of this 3 stuff are wrong and broke another of them. can be??
what else is there , Team??

I've seen the formatter cause it to be completely dead before.

[Ac.skywalker]

Well i guess not!! , cause i try with out formatter too and others and it wasnt work.
actually i replace the news parts(low voltage , high voltage ,dc controller) with the old ones, and try a mix. Its the same result.

There is something that i can see...i need more advice before i call HP . Please

[ucinn]

I believe if the formatter is not in the machine, it will be dead, so the only way to find out is take one from another machine for testing. That's what I did to find out.... the boards in these things suck.

[Ac.skywalker]

i not agree , couse how do u perform a engine test?? with the formatter?, without it thats how i do , and without the formatter the machines run or fans and motors get on ; plus i try with another formatter and it dosnt help!

machine still out service!!

Have you tried with the fuser out of the machine?.. maybe something in the fuser shorting out the PS... It's now a guessing game since you have replaced everything I can think of....I would try taking out the fuser and cart and see what happens..see if you can at least get fans. This is a very weird problem because usually one of those boards should do it.

[Ac.skywalker]

Yes Uccin, that was one of that all thing i did. Actually i call Hp support center and i give them all the information and test that i had.
They were thinking its time to get all the 3 componets change at same time, soo now we will se and im sure it will fix this weird problem...but i can hear anothers views.

Let me knwo team.....Thanks

Did you replace the ADF power supply or the engine power supply?

[Ac.skywalker]

not really. I replace the low voltage, high voltage and dc controller. But in other test i tested the printer with out ADF, trays, formatter and etc. Now im just waiting for the LV , HV and controller , that was a advise of Call center. If im wrong please explainme but that adf power sypply is the same of this 3 last parts??

Waiting news, thanks Team
