Translstor maybe the voltage was the problem and the off-brand low toner made it worse I fixed the voltage prob and the rest eventually worked itself out? After it told me the toner was low, it started behaving correctly. I’ve scanned and copied with it. Or am I barking up the wrong tree?

I’m pretty sure you can find the schematic for the supply. It took a couple days but the error returned. Usually the 5 volt line is the one that is regulated via opto-coupler.

Mine didn’t have that problem. I don’t know anything. The error also keeps the whole printer from powering down to low-power stand-by mode.

If you really have 3. A current sensing resistor BPR58 0. The caps seem good – tested out of circuit.

In-circuit it reads 0. If it were me I would just recap the power supply and be done with it Ttansistor 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 the page that you want Here is the link to where I had recapped this printer http: Here is a useless update: Is the voltage really 3.

What is the resolution of your meter? Last edited by golemmaster; dataeheet There is a variable resistor on the daughter board with the IC. After much poking around and identifying and looking at some data sheets and tracing some things out and measuring I have also read about these power supplies ttansistor bad caps.

The other outputs are as measured 5. Further troubleshooting at that point would require a schematic. The usual function of the resistor is to monitor a particular circuit and send over-current information to a processor.

I can’t work on it right now but I will get back to it sometime later. Thanks for listening anyway. I realized my ESR-micro v3. I’m going to run the machine till it fails and re-read the voltages. The “universe” won and I was just along for the ride.

Still works with no errors and goes to sleep.

In the printer’s old age, something drifted resulting in the 3. At this point, I would stop guessing and post the diagram so we can all have a good look. I learned a tiny bit. I’ve put the printer back together and turned it on.

All times are GMT I’ll get some pictures up in a little bit. All the usual suspects caps and solder joints a few touch-ups are fine.

The time now is It went to sleep which is something the error state did not allow. It’s been running for about two hours.

I replaced the toner cartridge with a genuine HP cartridge. 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.

If the sense resistor is supposed to be.
