The time now is Further troubleshooting at that point would require a schematic. The other voltages are unchanged. I learned a tiny bit.

Last edited by golemmaster; at If it were me I would just recap the power supply and be done with filethpe I have a HP all in one printer that would keep telling that it was not available Really it plugged in the wall the Ethernet cable hook up I would have reload the software for the printer for it to maybe work This is when I had with this printer and decided to recap the power supply and mother board of the printer before I send it to landfill and be done with it well after recapping both boards I not have any more problem with this printer Now my tablet dose not always show that printer available but is because HP app dose not really want to work with the Lollipop operating system of this tablet but there is a work around that works most of the time save it as a PDF file and then print ifletype page that you want Here is the link to where I had recapped this printer http: The “universe” won and I was just along for the ride.


I replaced the toner cartridge with a genuine HP cartridge. I have also read about these power supplies with bad caps.

Here is a useless update: A transixtor sensing resistor BPR58 0. All the usual suspects caps and solder joints a few touch-ups are fine. So maybe the voltage was the problem and the off-brand low toner made it worse I realized my ESR-micro v3. There is a variable resistor on the daughter board with the IC.

After it told me the toner was low, it started behaving fi,etype. I’m going to run the machine till it fails and re-read the voltages.

Thanks for listening anyway. If you really have 3.

The error also keeps the whole printer from powering down to low-power stand-by mode. It would only take about 10 minutes or less for the error to come up. I plugged the supply into the printer. No error so far. Find More Posts by golemmaster. I fixed the voltage prob and the rest eventually worked itself out? It took a couple days but the error returned.


It went to sleep which is something the error state did not allow.

I can’t work on it right now but I will get back to it sometime later. What is the resolution of your meter? Service manuals say to replace the scanner board but I read in a couple other forums that it is actually the power supply that causes the problem. At this point, I would stop guessing and filetgpe the diagram so we can all have a good look.

I’ll get some pictures up in a little bit. The other outputs are as measured 5. While watching my meter, I adjusted the resistor and was able to bring it down to 3.

Still works with no errors and goes to sleep.

Usually the 5 volt line is the one that is regulated via opto-coupler. Mine didn’t have that problem. Does anyone have experience with this or similar power supplies?
