Service manuals say to replace a10015 scanner board but I read in a couple other forums that it is actually the power supply that causes the problem. The error also keeps the whole printer from powering down to low-power stand-by mode. The other outputs are xatasheet measured 5.

The caps seem good – tested out of circuit. A current sensing resistor BPR58 0. Or am I barking up the wrong tree? Does anyone have experience with this or similar power supplies?

I’ll get some pictures up in a little bit.

Last edited by golemmaster; at If the sense resistor is supposed to be. The usual function of the resistor is to monitor a particular circuit and send over-current information to a processor. Further troubleshooting at that point would require a schematic. What is the resolution of your meter? Is the filetpe really 3. If you really have 3. I realized my ESR-micro v3.

In-circuit it reads 0.

I’m going to run the machine till it fails and re-read the voltages. I’m working on getting the pics up.

After much poking around and identifying and looking at some data sheets and tracing some things out and measuring All the usual suspects caps and solder joints a few touch-ups are fine.

In the printer’s old age, something drifted resulting in the 3.

There is a variable resistor on the daughter board with the IC. I plugged the supply into the printer. While watching my meter, I adjusted the resistor and was able to bring it down to 3. ttansistor

The other voltages are unchanged. I’ve put the printer back together and turned it on. It would only take about 10 minutes or less for the error to datasgeet up. It’s been running for about two hours.

It went to sleep which is something the error state did not allow. I’ve scanned and copied with it. No error so far. I transustor also read about these power supplies with bad caps. Mine didn’t have that problem. It took a couple days but the error returned. I can’t work on it right now but I will get back to it sometime later. I’m pretty sure you can dwtasheet the schematic for the supply.

I think you will find that it is similar to a computer power supply. Usually the 5 volt line is the one that is regulated via opto-coupler.

At this point, I would stop guessing and post the diagram so we can all have a good look. Here is a useless update: After it told me the toner was low, it started behaving correctly. I replaced the toner cartridge with a genuine HP cartridge. Transistod works with no errors and goes to sleep. So maybe tranxistor 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? I don’t know anything.

I learned a tiny bit. The “universe” won and I was just along for the ride.

Thanks for listening anyway. If it were me I would just recap the power supply and be done with it 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 od up I would have reload the software for the printer for it to maybe transitsor 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 datasheey 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: All times are GMT The time now is Find More Posts dtasheet golemmaster.
