Hi all,

Looking for some assistance. I'm running Windows Vista and have an Epson Scanner V100. I recently started having problems with the scanner as I keep getting an error when I try to scan something ("Epson Scan cannot be started"). I also have a BROTHER MFC-440CN all-in-one printer and both are plugged into the USB ports on the back of my TOWER. Weird thing is, my printer works FINE, but it's the scanner function that doesn't work. I tried to switch the USB plugs around and that worked a couple times. I don't seem to have a problem when I plug them into the USB ports in front of the tower.

I did go to Control Panel to remove the Epson from the Scanners and Cameras listing, but it won't let me. I can't right click it or check the Properties. I did uninstall Epson Scan and re-install it. That worked until I shut down and booted my computer the next day.

Thanks for your help everybody.Go Start, type in:
services.msc
Hit Enter.
Services window will open.
Scroll down to:
Windows Image Acquisition (WIA)
Make sure, this service is set to Automatic, and it Started, already.Windows Image Acquisition is already set to Automatic and status is Started.Are you saying, that both, Epson Scanner V100 (standalone), and scanner module of Brother MFC-440CN don't work?
And they both work, when plugged in to front panel USB?Yes. The Epson and the scanner on my Brother seem to work fine when I plug them in the front USB ports. But, I don't think the ports are damaged as the printer works and I've plugged a flash drive into both of them and that's okay.

Forgot to mention that when I attempt to manually start the Epson scanner, I get an error that says "Open Devinf.def File error." That's only when I can actually get it to work when it's plugged into the front ports.I did search for "Open Devinf.def File error", but all I got were Chinese pages.
Did you try to contact Epson?
I had similar problem: "Epson Scan cannot be started", but in my case, it was a problem with the service, I mentioned before, not running.
When I contacted Epson via email, they responded in next 24 hours. You may try it.1. USBDeview. The following utility, USBDeview by Nirsoft, may be useful. You can use it to clean up any "ghost" USB entries in your system registry. It may prove helpful with your problem. At any rate it provides a lot of useful information in a format that's easier to read than Microsoft's "Device Manager".

2. Device Manager. Have you checked the status of your USB devices/hubs/controllers under Microsoft's Device Manager utility? Any yellow or red flags, or any error statuses within device manager?
As scanners have PRETTY high power requirements you may want to unplug as many devices as you can when SCANNING...Thanks for your help, guys. Scanners still aren't working right. I'll contact EPSON.Quote from: WillDLeeEsq on November 15, 2007, 04:08:40 PM
