Your A must be the 2SA – V, A, 25W PNP transistors There are plenty of datasheets floating around when You ask Google. the only other transistors in this amp are 3 c and 2 a per File Type: jpg. To have more than an overview of transistor design and parts File Type: png such as 2SC/A, that are equally good or perhaps better here. at the datasheets for original BC V BC Philips – datasheet pdf.

error HP MFP power supply – Badcaps Forums
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 transistorr 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: I learned a tiny bit.
The caps seem good – filetgpe out of circuit. Still works with no errors and goes to sleep. I don’t know anything. Find More Posts by Longbow.
At this point, I would stop transisor and post the diagram so we can all have a good look. I’m pretty sure you can find the schematic for the supply. I’ll get some pictures up in a little bit.

It would only take about 10 minutes or less for the error to come fransistor. There is a variable resistor on the daughter board with the IC. In-circuit it reads 0. The time now is I’m going to run the machine till it fails and re-read the voltages.
It took a couple days but the error returned. I’ve put the printer back together and turned it on. Find More Posts by golemmaster. A current sensing resistor BPR58 0. I replaced the toner cartridge with a genuine HP cartridge.

Last edited by golemmaster; at Further troubleshooting at that point would require a schematic. I realized my ESR-micro v3. All times are GMT I have also read about these power supplies with bad caps. If you really have 3.
All the usual suspects caps and solder joints a few touch-ups are fine. While watching my meter, I adjusted the resistor and was able to bring it down to 3.
I think you will find that it is similar to a computer power supply. Or am I barking up the wrong tree? Mine didn’t have that problem. 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. Is the voltage really 3. The error also keeps the whole printer from powering down to low-power stand-by mode.
Usually the 5 volt line is the one that is regulated via opto-coupler. So maybe the voltage was the problem and the off-brand low toner made it worse It went to sleep which is something the error state did not allow.
