Doesn't turn on!

I can't get the scanner to be "on". I used it a couple of days ago and it worked fine ... has been perfect for the 2.5 years I've had it. Everything is plugged in and I just finished the driver download sequence. I have in on an iMac for the last year. Could it have "died" on me?

Re: Doesn't turn on!

I had a "Doh!" moment the day after posting my problem. As I was packing up the scanner to put it in the attic, I suddenly noticed the on/off switch on the side. I'd never noticed it before. Connecting everything and flicking it to ON made the lights come on and my scanner worked perfectly. I'd recommend switching off at the mains after every use, however, as there is something a bit dodgy about the power supplies.

Re: Doesn't turn on!

I had the same problem a year ago or so. The solution was to replace the power cord. I have the problem again even though I haven't used the scanner much in the meantime. I think there's a power trickle effect going on and I should have unplugged the cord from the outlet when not in use.

When I turn on the Epson v700 scanner, only the little blue light on top blinks but the scanner will not fully turn on and it makes no sounds. It was working fine a few days ago. I never had any problems...

If the drive icon is displaying on My Computers then nothing to worry.. if not check all cables or reinstall the drivers. if still it persists go for repair...

Make sure you have Adobe acrobat or similar installed so that you have PDF available on the PC. It may also be in the software for the Epson. I had a scanner a few years ago whose software excluded PDF and I ended up installing new software of a generic printer / scanner to use Adobe PDF

No software to install epson 2490 scanner

Try going to Then go to the Drivers and Support page and look up your scanner. The Drivers and Downloads link is one of the first items in the list. I could not find a model 2490 on the site.

I hope this helps.

Need a document feeder for 4990 scanner

I don't believe it is possible to add a paper feed to this scanner. The only hopper fed scanner of which I'm aware is the Kodak s1220.

Scanning App won't open.

Actually, it's okay- I just installed the windows drivers under Boot Camp, and that seemed to 'reset' the scanner under OSX.

Epson Perfection V200 Photo scanner

You have tired all the computery things seemingly
but it is work trying some more
Remove all software.- using the Epson Uninstall routine .
and just to be sure go to Programs.Epson and maually delte all you can find.
Make sure that when you re install- the computer is off line and the ant virus program is disabled.
That should sort the problem Computer wise.
When you go to operate the scanner- does it then go through the motions of Scanning but no light - is that it?
If it is - there is nothing for it but to replace ther scanner
To bad about the warranty card but if you have the sales recieipt
And purchased less than a year ago - the the seller has a responsability [UK wise any way]
But a pleading message toi Epson may surprise you too.

Scanning slides with the Epson Perfection 1250

To be honest, I have no idea of how you were able to scan larger transparencies in the past. The scanner and its software were never designed to do this and there is no workaround.
