Epson scanner communications problem

Alan Edward Klein · Apr 30, 2020

I'm setting up a new V850 scanner and I have a problem. Computer cannot communicate with scanner. See picture. I was having this problem on and off with the V600 and use to have to reinstall the program. But that doesn;t seem to work with the V850. The light is green on the scanner and I unlocked it with the two ship switches. I believe the computer is see the scanner because I have a program that check the status of everything and it see it in the report. I've tried different USB jacks. I'm running WIndows 10 64 bit Dell computer. Thanks for your help.

I've owned many Epson scanners on many computers and have never seen this problem. Have you tried another computer?

I started getting that at the end of a high resolution scan but the scanned image file was saved so I just ignored it. The problem may be with the recent Windows updates and we'll have to wait for Epson to catch up to Microsoft.
When I'm image editing Windows sees the computer as idle so background apps and services start running causing delays in the response from the computer including not reading the scanner as the OS is doing something else. A possible workaround is to disconnect from the internet when scanning or editing. Also check Epson's web site and verify you have the latest version of the software.

Verify your Windows installation is good: https://support.microsoft.com/en-us/search?query=sfc+in+Windows+10&ui=en-US&rs=en-US&ad=US

I called Epson in California and got connected to their expert in the Philippines. He was able to solve my problem. He had me delete the scanner in Device Manager > Imaging Device. I then uninstalled the program and installed it again from their website rather than the DVD that came with the unit. Also, you have to install the USB after the software is loaded and with the scanner power ON. Everything working now. Thanks all.

Good tip on the sequence. I'm ordering a V850 from B&H and they told me to download the software and driver (I think this is what you mean by the "USB") from the web site and not even try the cd, which is pretty normal for peripheral devices. I have a Mac, though, and my sequence may be slightly different.

George, the USB is the cable that connects the computer to the scanner. I'm not sure what it's called with a Mac. I just scanned my first three 4x5's yesterday and posted in Flickr. https://www.flickr.com/photos/alanklein2000/albums/72157714124881023

I used Epsonscan to scan because I'm familiar with it from the V600. I want to go back and re-scan some of my older medium format film to compare the two scanners. I bought the V850 Pro that came with Silverfast XE and Xrite color profile software for the scanner, but haven't tried them yet. Good luck. Feel free to contact me if you have any questions. Alan.

Did you try a different USB cable?

It was another issue. See my post #4. Thanks.

Correct. To clarify what happened (and I made the same mistake, even though I should know better)-- When you plug in a USB device, Windows scans for a driver, and if it can't find an exact match, it installs a generic driver. Then even though you install the Epson driver after that, Windows is still insisting on using the generic driver. This has been a problem in Windows since Windows 98 (or earlier).

By deleting the device and plugging it back in, you force Windows to re-scan the driver database while "getting your device ready". In theory, moving the USB connector to a different controller should force Windows to re-scan-- But the two front USB ports are usually on the same controller, so you'd have to switch from a back port to a front port, or vice versa (or USB 2.0 to USB 3.x).

So the rule is, always install the driver, THEN connect the USB cable. I have a vague memory that the instructions said plug it in, THEN run the software, but it was late at night, and I wouldn't swear to it.

Glad you got it working.

Oh, and for Silverfast, you're probably better off installing from the CD, registering it (which requires the physical CD), and then downloading the update from Silverfast.

Yes, that driver issue with WIndows I;ve had before. As an aside I tried try switching to the top USB ports on my Dell XPS desktop but that didn't make a difference. It required deleting the device and reinstalling the software, then plugging in the cable.

It is usually in installation manual. Install software (it will install driver), and only after it plug in, turn on device.
But if it is wrong software, it is not helping. And this is common problem indeed. Software on CD which is tossed with shipiping doesn't get updated. Some gadgets makers stopped shipping CD with software and drivers. Even manuals has to be taken from manufacture site. So, shipping of old CD is eliminated.
I have to deal with IBM servers once. Not only they were shipping them in parts and by separate shipping of those parts, but all CD were with way too old drivers.
I was glad we switched to Dell back then

I've been using Dell for 15 or 20 years. Viruses use to crap them out. So I'd eventually replace them. But Windows has gotten better and my Kaspersky virus protection software seems to be doing it's job. The Russians seem to know what they're doing even if Putin is listening in. So I've much less problems since Windows 7 and now Windows 10.

Dell has good support documentation. So when I've had to replace a battery or something else, rare occasions anyway, their service documentation was very descriptive and helpful. Most new software that comes on a CD usually has an automatic update where the program asks you if you want to download updates. The Epsonscan software did have that. There's also an auto update routine that operates to checks the Epson site for new updates from time to time. I think I set mine on a one month interval.

Auto update is good if software initially provided was correct, not too old.
Kaspersky and Norton are too intrusive and slowing down computers. Outdated solutions. Just like Russian photo cameras and minds.
I leave computer with what comes with OS or install ZoneAlarm.
