    This afternoon I found a printer waiting for the trashman. And a good
    friend needs a printer, at least he did recently. Kismet.

    Nothing happens when I press the On/off button,

    But in the back, the little green LED is lit up when it's plugged in,
    not flickering and not dimming.

    I've done what iiuc is a hard reset: Unplugged, hold down the On button
    for 30 seconds. No change.

    1) Easy to detach the power supply, It shows various voltages, from 6
    to 19 with several others in between, but they only show for a second or
    so. Then the meter drops to zero.

    2) OTOH, when using the AC scale, it shows 46VAC consistently, no going
    on and off.

    Were it not for point 2, I would say that I think I remember that this
    is a popular symptom, right? representing a common problem, right?

    But because if of point 2, I'm not so sure.

    But still I think: In short, the power supply, the brick, is no good,
    right? ???? Even though the LED does not dim or flicker. ????


    Power supply is HP F5S43-60001 Supposed to put out 22V DC up to 455ma.
    I think HP sells it for about $40 and but ebay has 54 listings for $10,
    all in China, and 3 listings in the USA for 27 or 20. Probably going to
    visit him next Sunday so shipping from China would take too long. https://www.ebay.com/itm/133494122165

    Printer is HP Office Jet 3830 All-in-one, plus it's wireless, and has
    a document feeder, but weighs only 12 pounds. Uses a tri-color
    cartridge and ink might be expensive, but I don't think my friend prints
    a lot. (Currently he sends stuff to be printed to his daughter-in-law
    who lives nearby, and someone there prints it for him.) https://www.hp.com/us-en/shop/pdp/hp-officejet-3830-all-in-one-printer#recommendedAccessories

    He used to have all this stuff but a house fire melted his computer, and
    melted the backup drive that was next to it!!

    Amazon has the printer renewed for $249 and "in New condition" for $176
    more than that. That's how they put it. Comes to $425.

    Thanks. I tried everything suggested but nothing helped.

    I also disconnected power supply before measuring the voltage, and, more importantly, I used the 200v range instead of 20, and the voltage was
    21,5 and very stable. I think that's close enough to 22 that that is
    not the problem.

    I wonder about the suggestion to remove the cartridges and see if starts
    then. Hard to believe that could help. The thing seems to have been made
    in 2016, but the cartridges don't expire until the end of this month and
    the end of next month.

    I'm going to google some mroe but I may be out of ideas. I don't even
    know where the rest of circuitry is, and I dont' see screws to remove.

    Other people have complained about the same symptoms.

    It's out of production, but Amazon has reconditioned and like new (for
    425). It's a very nice machine. It's small, only 12 pounds, and does everything, copy, scan, print, fax, except for automatic 2-sided
    printing (which I think is great, and wouldn't want to do without.)

    I see there is more to do in your link. I'll see if I can use that to
    find the problem. I've got until next sunday morning to fix it or die
    trying.
