In the printer’s old age, something drifted resulting in the 3.
Is the voltage really 3. I have also read about these power supplies with bad caps.
Or am I barking up the wrong tree? I’m going to run the machine till it fails and re-read the voltages. The time now is I plugged the supply into the printer. 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 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 dqtasheet 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 transidtor 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: The “universe” won and I was just along for the ride.

I can’t work on it right now but I will get back to a10015 sometime later. There is a variable resistor on the daughter board with the IC. All the usual suspects caps and solder joints a few touch-ups are fine. I learned a tiny bit. The caps seem good – tested out of circuit. In-circuit it reads 0.
The other filetypee are unchanged. I’m working on getting the pics up. I fixed the voltage prob and the rest eventually worked itself out? I don’t know anything. It’s been running for about two giletype. It would only take about 10 minutes or less for the error to come up. Last edited by golemmaster; at What is the resolution of your meter? I realized my ESR-micro v3. If you really have 3.
A current sensing resistor BPR58 0. After much poking around and identifying and looking at some data sheets and tracing some things out and measuring At this point, I would stop guessing and post the diagram so we can all have a good look.

While watching my meter, I adjusted the resistor and was able to xatasheet it down to 3. I’ll get some pictures up in a little bit.
I think you will find that it is similar to a computer power supply. It went to a10155 which is something the error state did not allow. Thanks for listening anyway. Here is a useless update: Still works with no errors and goes to sleep. I’ve scanned and copied with it. The error also keeps the whole printer from powering down to low-power stand-by mode. So maybe the voltage was the problem and the off-brand low toner made it worse No error so far.

The other outputs are as measured 5. All times are GMT It took a couple days but the error returned. I’m pretty sure you can find the schematic for the supply. Usually the 5 volt line is the one that is regulated via opto-coupler.
