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.

The “universe” won and I was just along for the ride. It would only take about 10 minutes or less for the fransistor to come up. Mine didn’t have that problem. Last edited by golemmaster; at After it told flietype the toner was low, it started behaving correctly. 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.

I have also read about these power supplies with bad caps. Thanks for listening anyway. I replaced the toner cartridge with a genuine HP cartridge. I’ll get some pictures up in a little bit.

I’ve put the printer back together and turned it on. Here is a useless update: While watching my meter, I adjusted the resistor and was able to bring it down to 3. The other voltages are unchanged. It’s been running for about two hours. The time now is I dagasheet the supply into the printer. I’m going to run the machine till it fails and re-read the voltages.

I fixed the voltage prob and the rest eventually worked itself out? No error so far. The other outputs are as measured 5.

At this point, I would stop guessing and post the diagram so we can all have a good look. Is the voltage really 3. I can’t work on it right now but I will get back to it sometime later. Still works with no errors and goes to sleep. The usual function of the resistor is to monitor a particular circuit and send over-current information to a processor.

What is the resolution of your meter? 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 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 datashedt print the page that you want Here is the link to where I had recapped this printer http: It took a couple days but datasheett error returned.

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. If you really have 3. All the usual suspects caps and solder joints a few touch-ups are fine.

All times are GMT A current sensing resistor BPR58 0. 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 In-circuit it reads 0.

I think you will find that it is similar to a computer power supply. The error also keeps the whole printer from powering down to low-power stand-by mode. I realized my ESR-micro v3.

Further troubleshooting at that point would require a schematic. So maybe the voltage was the problem and the off-brand low toner made it worse I don’t know anything. Filetypd the 5 volt line is the one that is regulated via opto-coupler.
