Epson Scan reports an error "EPSON Scan cannot be started" and there are no errors in Device Manager.
I receive the message "Please install supported TWAIN driver" and there are no errors in Device Manager.
I want to fully remove the scanner driver.
You may need to uninstall the Epson scanner driver if you simply wish to remove the Epson software from your system, or you wish to remove the software to try to resolve a problem you are experiencing with the Epson scanner, driver, or software.
If you have been experiencing difficulties scanning to your computer, there may be a communication issue. Ensure that you have followed the troubleshooting article that addresses the issue you are experiencing. If the issue remains, the scanner driver may need to be fully uninstalled.
This will remove all currently installed Epson scanners.
Important: This article assumes that your scanner is operational (e.g. displaying no errors) and addresses the full uninstall process only.
Browse to the inf folder from Windows Explorer, or My Computer. (Windows 2000: c:\winnt\inf, Windows XP: c:\windows\inf)
Open Windows Explorer or My Computer.
Navigate to the drive that Windows is installed on (usually C:).
Open the winnt folder (Windows 2000), or windows folder (Windows XP).
Open theinf folder.
If you cannot locate the inf folder open the Start menu and select Run. Type inf into the blank Open: box then press Enter.
You will now need to search for the Epson 'oem' files in the Windows inffolder.
Locate the files labelled OEMxx.inf (where xx is a number from 0, 1, 2, etc. upwards). The oem files you locate may not display the .infextension.
There are normally two oem files that share the same number. For example with oem1 there would normally be oem1 and oem1.PNF.
oem.inf file: oem.PNF file:
Start with the first oem.inf file (usually oem0.inf).
You cannot open a .PNF file.
Double-click on the file and it will open in the Notepad program.
Check for "SEIKO EPSON" or "EPSON" within the first few lines of text.
If it does not say "SEIKO EPSON" or "EPSON" within the first few lines, close the file and check the next oem file. To close a file, click on the close icon found in the top-right of the program window.
If "SEIKO EPSON" is listed within the first few lines and the scanner details are listed further down, close and delete the file. To delete it, right-click on the file icon then left-click on Delete from the menu.
You MUST NOT delete any OEMxx files that do not contain "SEIKO EPSON".
Click Yes to the "Confirm Delete" prompt, to send the file to the Recycle Bin. Then delete its corresponding oem.pnf file.
In the example below, oem109.inf is a SEIKO EPSON file. This should be deleted along with oem109.PNF.
Continue to check each OEMxx.inf file in turn, following the procedure above.
Once all OEMxx.inf files have been checked, close the inf folder.
Open My Computer then open your hard disk drive (usually C:).
Open the Documents and Settings folder, followed by the folder with your user name on it e.g. "PC User".
In this folder, open the Program Data folder then the EPSON folder.
Within the EPSON folder, delete the ESCNDV folder.
If your scanner uses EPSON TWAIN, an ESCNDV folder will not be listed - look for and delete the EPFB* (where * represents a number e.g. EPFB5).
Next, click on the Tools option from across the top and select Folder Options.
A window will appear, click on the View tab.
Underneath Hidden files and folders ensure that the option for Show hidden files and folders is selected and then click OK.
Return to Documents and Settings and open the folder that has your username on it.
Open the Local settings folder.
Open the Temp folder and look for the following files:
'xxx' represents a number such as Twain001.MTX, Twain002.MTX, Twunk002.MTX etc.
If these files already exist they are just read. Some cleaning programs operate by overwriting the contents of these files but not deleting the filename. Then the Source Manager is unable to read the data and does not create new copies of the files as they already exist. If this happens the Source Manager is unable to open, thus there is no TWAIN support available for any application.
Delete the Twain.log, Twainxxx.MTX, Twunkxxx.MTX files from the folder. Close all windows back to the Desktop and restart the computer.
