Help! The scanner won't turn on! Is it fried?

Hello,

my scanner won't turn on anymore, as if there's no power going through!
how can I tell if it's burned out?
how can I know if it's just a part or a component that needs changing?

my scanner is a Hp Scanjet 5470c (it's been out of warranty for a long time)
Serial number: CN21F16067

my computer is a Fujitsu Siemens

I'm on Windows XP (pack 2)

here's what happened: I turned on my scanner. the computer didn't recognize it ("scanner not found"). this has happened several times before and the solution has always been to unplug and plug the USB back in. this time it wasn't enough. so I turned off the scanner, then unplugged it from the USB and the power outlet, restarted my computer, reconnected everything and then... the scanner doesn't turn on at all! as if it had burned out.

also, it's like my scanner has disappeared from my computer! I can't see it either in my computer or in the device manager!

I completely uninstalled and reinstalled it but it still won't turn on!

I contacted Hp to ask for help, to no avail! They sent me back to their website. On that site, the only information I found regarding my problem is that the failure comes either from:

- the power module
- the cord
- the scanner

it's crazy how much that helps!!!

If it were a software issue, I might have found a solution, but if it's hardware-related, I know absolutely nothing!

I also can't afford to take it in for repairs.
If it's just the power cord that needs to be changed, it would be cheaper for me to buy a new one.

So I'm reaching out to hardware experts to help me solve my problem. It's quite urgent because I need this device for my work.

If any of you could at least explain to me how to test the scanner to ensure it has burned out or explain how to open it and tinker with it (if possible, of course) to diagnose the failure, that would be really nice!
Configuration: Windows XP Firefox 3.0.10

Do you have the ability to check or have the output of the power supply checked?
You need to know if you have the voltage indicated on the power supply at that output.

Thank you, finally a response!

The problem is that I have no idea how to go about controlling this. I know absolutely nothing about hardware.

What exactly is this output and what do I need to control it?

Is there no technicians on this site or what?

I thought I would find an answer quickly...

Hi,

Check your wall outlet, the power cord.
Either the scanner is not receiving power or it is receiving power and is malfunctioning.
(This won't be resolved over the internet and this site is not a workshop.)

As an illustrator, I also rely heavily on my scanner, and I have the same problem as you: it won't turn on! So I don't know if it's the power supply or something else... HELP US!

lol welcome to the club of the struggling ones then! lol

I have no answers!!!

I thought there were professionals here to answer this kind of question, which, I must say, doesn't seem complicated for someone who knows a bit about the material...

HEEEEEELLLLLP!!!

thank you jiminsk

I'm not that useless... lol

Of course, the first thing I did was check that my device was properly plugged in, using different wall outlets.

Otherwise, yes, I noticed that this site is not a workshop, but it is still well-known and frequented enough for at least one experienced person or a technician to see my message and guide me in my approach!

Otherwise, why call this forum "Equipment/Hardware"???

Re-

The hardware forum deals with this kind of issues, but what do you want us to say other than what seems obvious? The only viable option is to take this scanner for repairs, unfortunately.
It's impossible to test your power supply from here.
This forum mainly deals with proper installation and troubleshooting of device drivers, thus focusing on the software troubleshooting of hardware.

Thank you, Jiminsk

Let’s say I would have liked to test the device myself before taking it in for repair because if it’s just the cord that’s burnt out, it would cost me less to buy a new one than to drop off the scanner for repairs.

I have limited financial resources, so I’m first trying to manage on my own to keep costs down.

So at the outset, answering:

“Where is the power supply unit located?”
“How to test it, as well as the power cord?”
“What equipment?” (I know nothing about testers)

would already help me a lot!

Re - ,

Don't take it the wrong way, but I doubt anyone on this forum would tell you: go ahead, plug your scanner into the socket, open it up, and stick a screwdriver anywhere until you feel if there's some juice. Remember that there can be serious consequences to tampering with electrical equipment, even when it's off.

Let someone who is used to this kind of work handle it; 220V in your fingers is no joke.

Sorry for your trouble.
