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.

At this point, I would stop guessing and post the diagram so we can all have a good look. There is a variable resistor on the daughter board a1105 the IC. The other voltages are unchanged. It went to sleep which is something the error state did not allow.
The error also keeps the whole printer from powering down to low-power stand-by mode. After much poking around and identifying and looking at some data sheets and tracing some things out and measuring All times are GMT 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. Or am I barking up the wrong tree?
Is the voltage really 3. I fixed the voltage prob and the rest eventually worked itself out? In-circuit it reads 0.

I’ll get some pictures up in a little bit. I have also read about these power supplies with bad caps.
I think you will find that it is similar to a computer power supply. Trasistor replaced the toner cartridge with a genuine HP cartridge. It’s been running for about two hours.
After it told me the toner was low, it started behaving correctly. I can’t work on it right now but I will get back to it sometime later. Here is a useless update: While watching my meter, I adjusted the resistor and was able to bring it down to 3. All the usual suspects caps and solder joints a few touch-ups are fine.
The “universe” won and I was just along for the ride. The time now is I realized my ESR-micro v3. I’m working on getting the pics up.

Find More Posts by Longbow. I don’t know anything. I plugged the supply into the printer. I’m pretty sure you can find the schematic for the supply. It would only take about 10 minutes or less for the error to come up. It took a couple days but the error returned. What is the resolution of your meter?
Does anyone have experience with this or similar power supplies? In the printer’s old age, something drifted resulting in the 3.
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 fileype HP app dose not really want to work with the Lollipop operating system of this tablet but there is a work around that filety;e 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:
