Windows Forum / Windows XP / General Topics 2 / May 2008Windows Unable To Recognize Scanner Driver
Hello, For some reason my scanner won't work anymore. When I try to use it, I get the following message: "C:\Program Files\EPSON\Smart Panel\File.exe\:"/T:EPSON TWAIN 5" Application can't be found." When I check Device Manager, it shows the correct scanner and indicates that the driver is in place. When I remove and re-install the Twain driver, the message I get in the notification area is that new hardware has been found and that it is ready to use. I haven't moved any files from where they were installed by the installation software for Smart Panel, nor by the Twain installer. I'd sure appreciate any advice as to what could be the problem. Thanks in advance, Danno Try disconnecting the scanner, then uninstall the scanner software & twain drivers. After the install shut the PC down, then connect the scanner and reboot.

[quoted text clipped - 22 lines] >> Thanks in advance, >> Danno I have had endless trouble with my Canon FS2710. It all boiled down to installing the adaptec\aspi in drive C: Having placed the files there, of course I had to run the aspiinst.exe. Then I installed the scanner and have not had any trouble since. There is even a program called aspichk.exe which does what the name suggests, check the installation. Børge in sunny Perth, Australia Thanks JS, but I've tried that until I'm blue in the face... to no avail. In fact I just tried it now, one more time... at your suggestion. Device Manager says the scanner is installed and is working properly. It says the driver is (Twain) is there. And the entire uninstall and re-install of Epson's Smart Panel software went ahead smoothly. But again.... Smart Panel can't seem to find the Twain driver. This is a mystery to me, since it all worked well in the past. The operating system was freshly installed a little over a month ago, and the scanner has worked since then. When I disconnect the scanner, windows detects that it has been removed, and windows also detects when I reconnect the scanner. Any further suggestions would be welcome.

I'll try it again today, and this time, I'll delete the directory too. I'll let you know what happens. Thanks again!

[quoted text clipped - 48 lines] >>>> Thanks in advance, >>>> Danno Well I'm still having no luck. The device manager says the scanner's driver is in place and that the hardware is working properly. But the Smart Panel software can't find the driver. The software is there... the driver is there, but the two are not communicating. I've tried every way I can think of to uninstall all the software and re-install it, but to no avail. I'd sure appreciate any further advice. It would be nice to scan documents I need for work.

First check Epson's web site for the latest drivers and software and download to a folder. Now follow these steps 1) Disconnect the scanner. 2) Uninstall the software and twain drivers. 3) Remove any folders/files related to the twain drivers or scanner software. 4) Check Device Manager and remove any entries if necessary. 5) Create a Restore Point 6) Scan registry using the brand name/make of the scanner as key word for search. (Delete any entries found, but be certain it's a scanner related entry) 7) Reboot the PC and once again check Device Manager, it should show noting for the scanner. 8) Now reinstall the software and twain drivers. 9) Shutdown the PC. 10) With the PC power off, connect the scanner and then restart/boot to Windows.

I recently purchased a USB hub and I'm not certain it's working properly. As far as I can tell, the drivers for it are updated. But on occasion, I've unplugged the scanner from one USB port and I did not get a signal that the hardware had been unplugged. Then when I plugged it into a different port, the hardware was detected. So right now, I have the scanner plugged directly into one of the computer's ports and it (that port) seems to be working fine. Just to make sure all the ports are working correctly, could you refresh my mind about how to update those drivers or to test those ports? I'm so busy today I can hardly stay on any one topic for long. lol Thanks again! You just might have zeroed in on a key issue I've been more or less ignoring. Dan > Almost forgot: It's might help if you try a different USB port if you > scanner is USB> [quoted text clipped - 112 lines] >>>>>>>>> Thanks in advance, >>>>>>>>> Danno Start with Device Manager, you can (like your scanner) see if there are any problems.

There were 13 entries for USB devices. I don't think I even have that many USB ports, but in any event, I was able to find driver updates for two of them. Maybe that's going to turn out to be the best solution yet. But I'll also go through the sequence you detailed earlier. I'll do that later tonight and let you know the outcome. Thanks again for your interest and advice. Dan > Start with Device Manager, you can (like your scanner) see if there are > any problems. [quoted text clipped - 137 lines] >>>>>>>>>>> Thanks in advance, >>>>>>>>>>> Danno Just though of another way to test your twain software install. There a graphics editor named IrfanView. http://www.irfanview.com/ If you download, install and run this software, located in the menu bar is an option named 'File'. On selecting the 'File' option you should find an option (near the bottom of the list) to select 'Select TWAIN Source', click on this option and a popup should then display valid Twain sources like you scanner. If you see your scanner listed, select it, and then try to scan an object (Photo). JS > Ok thanks JS. I'll try that sequence exactly... tonight just to ensure I > don't screw anything up during the afternoon when I need my computer for [quoted text clipped - 107 lines] >>>>>>>> Thanks in advance, >>>>>>>> Danno Well JS, you're not gonna believe this, but I tried every single thing you outlined for me, and still.... that damned scammer won't work. I uninstalled and re-installed all software exactly as detailed, and I still get the message that the Twain application can't be found. Yet it's there right in front of the nose of the Smart Panel (the software that needs Twain). I also downloaded Irfan View and clicked "Select TWAIN Source". Both Twain and the scanner itself appeared as options. When I select either of them and try to scan something, I still get the same error message. But one more question. When I select a TWAIN source, what should I expect Irfan View to do? Because it doesn't seem to do anything when I select a TWAIN source. Maybe it too can't connect with TWAIN. Dan > Just though of another way to test your twain software install. > There a graphics editor named IrfanView. [quoted text clipped - 122 lines] >>>>>>>>> Thanks in advance, >>>>>>>>> Danno By selecting Twain Source from the file menu it should load your Epson software and then scan. If you choose the 'Copy Shop' option also in the file menu you have the ability to bypass the Epson software and directly scan a photo into IrfanView. Try 'Copy Shop' and let me know what happens. Note that 'Copy Shop' will list both your Epson Photo editing/scanning software and the hardware name (make & model) of your scanner when you click on Copy Shop's 'Select Twain Source' button. You should choose the Epson hardware option. For instance on my PC the Photo editing/scanner software is named: 'HP Precisionscan Pro 3.1' The second entry in Copy Shop's 'Select Twain Source' list is my scanner make and model which shows as: 'WIA-Hewlett-Packard Scanjet 5470C 1.0' So for me using Copy Shop I select the second entry when asked to select a Twain Source. I then check the 'Show Twain Preview' box. (I check this option so the scanned image does not go directly to the printer, but instead is displayed in IrfanView). Next I click the 'Start' button located a the bottom of the Copy Shop window to start the scan.

I [quoted text clipped - 138 lines] >>>>>>>>>> Thanks in advance, >>>>>>>>>> Danno JS, I tried using 'Copy Shop' as you outlined, and indeed it does list my Epson scanning software which is called "Smart Panel", and it also properly recognizes the scanner make and model (Epson Perfection 1250), but to tell you the truth, it's hardly "perfection". lol Anyway, when I selected to scan a color photo, Irfan View tried and tried to reach the scanner but eventually gave me a message that it couldn't find the scanner, although it listed it in the options. Actually, a message popped up saying "Irfan View encountered a problem and had to be shut down". I just tried it again, and this time, when I go to 'Copy Shop' and click "select TWAIN source", and then select the scanner itself.... nothing happens. The first time I tried it, Irfan View tried to scan, but now it won't try. I think it knows there's something wrong with Twain and wants nothing to do with this problem. lol Anyway, I have to put this pain in the a.s issue to bed for tonight, and put myself in bed for the night in a couple of hours. In the meantime, I need some down time. Have a great night. And thanks again for so much effort. Dan > By selecting Twain Source from the file menu it should load your > Epson software and then scan. [quoted text clipped - 168 lines] >>>>>>>>>>> Thanks in advance, >>>>>>>>>>> Danno To anyone who's still following this thread, I'm more baffled now than ever. Just for the heck of it, I tried the scanner this morning and the damned thing works. JS and I tried everything we could think of, and couldn't get the Epson Smart Panel software to recognize that the Twain drivers were there. And now, a week later... the scanner works. I've done absolutely nothing since the last series of failed efforts. Go figure!

Cable not fully inserted in scanner or PC. Your using Windows Service Pack 3 (just kidding) Check driver status each time you boot the PC, does it change from OK to having a problem and since your scanner is currently working I assume the driver status shows as OK?

So maybe the message I'm getting doesn't really mean it can't find the Twain drivers... maybe it means it can't find the scanner itself? Bad cable or bad connection might be the real issue. Good idea JS. I'll check that more closely. > Possible bad USB cable? > Cable not fully inserted in scanner or PC. [quoted text clipped - 217 lines] >>>>>>>>>>>>>> Thanks in advance, >>>>>>>>>>>>>> Danno JS, just a quick question! When I scan the files and folders for anything Twain related, I can still find a few .dlls that are in the Windows directory, even after uninstalling Twain from my computer. These .dlls are definitely related to the Twain application, but is it OK to delete them even from Windows? Like this one for example, which is located at C:\Windows\twain_32.dll. Also in this folder are 3 files named 'twain.dll', 'twunk_16', 'twunk_32', and I've verified that they are all related to the Twain drivers. Would it be OK to delete them even though they're in the Windows directory? > Ok, this is the way I would do it given the info you provided. > First check Epson's web site for the latest drivers and software [quoted text clipped - 96 lines] >>>>>>> Thanks in advance, >>>>>>> Danno I'd leave them as is for now.
