DATASHEET OF A1015 TRANSISTOR FILETYPE PDF
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 other outputs are as measured 5. So maybe the voltage was the problem and the off-brand low toner made it worse All the usual suspects caps and solder joints a few touch-ups are fine. What is the resolution of your meter?

The usual function of the resistor is to monitor a particular circuit and send over-current information to a processor. The “universe” won and I was just along for the ride.
Last edited by golemmaster; at If it were me I would just recap datasheeet 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 darasheet 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: Mine didn’t have that problem.
It’s been running for about two hours. Still works with no errors and goes to sleep.
At this point, I would stop guessing and post the diagram so we can all have a good look. 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.
In the printer’s old age, something drifted resulting in the 3.

I’ve scanned and copied with it. After much poking around and identifying and looking at some data sheets and tracing some things out and measuring Does anyone have experience with this or similar power supplies?
I’m working on getting the pics ttansistor. After it told me the toner was low, it started behaving correctly. I have also read about these power supplies with bad caps. It took a couple days but the error returned. Further troubleshooting at that point would require a schematic. No error so far. If the sense resistor is supposed to be. Usually the 5 volt line is the one that is regulated via opto-coupler.
There is a variable resistor on the daughter board with the IC. I don’t know anything. I think you will find that it is similar to a computer power supply. I’m going to run the machine till it fails and re-read the voltages. The time now is I’ll get some pictures up in a little bit.

Here is a useless update: Thanks for listening anyway. I realized my ESR-micro v3. It would only take about 10 minutes datashheet less for the error to come up. Find More Posts by Longbow.

It went to sleep which is something the error state did not allow. In-circuit it reads 0. I replaced the toner cartridge with a dattasheet HP cartridge.
I learned a transistir bit. If you really have 3. I’ve put the printer back together and turned it on. Is the voltage really 3.
Or am I barking up the wrong tree? The caps seem good – darasheet out of circuit. I fixed the voltage prob and the rest eventually worked itself out?
