  5. Browse to the inf folder from Windows Explorer, or My Computer. (Windows 2000: c:\winnt\inf, Windows XP: c:\windows\inf)



    1. Open Windows Explorer or My Computer.

    2. Navigate to the drive that Windows is installed on (usually C:).

    3. Open the winnt folder (Windows 2000), or windows folder (Windows XP).

    4. Open the inf folder.

      Notes Icon Note:

      If you cannot locate the inf folder open the Start menu and select Run. Type inf into the blank Open: box then press Enter.


  6. You will now need to search for the Epson 'oem' files in the Windows inf folder.



    1. 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 .inf extension.

      INF Folder


    2. 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:


    3. Start with the first oem.inf file (usually oem0.inf).

      Notes Icon Note:

      You cannot open a .PNF file.


    4. Double-click on the file and it will open in the Notepad program.

    5. Check for "SEIKO EPSON" or "EPSON" within the first few lines of text.

    6. 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.

    7. 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.

      Caution Icon Caution:

      You MUST NOT delete any OEMxx files that do not contain "SEIKO EPSON".


    8. 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.

  7. Remove the Epson scanner files from twain_32 in the Windows folder.



    1. Open Windows Explorer or My Computer.

    2. Open the windows folder (windows on XP, winnt on 2000).

    3. Double-click on the yellow twain_32 folder.


    4. If there is a folder called escndv, right-click on the escndv folder and left-click on Delete.


    5. Click Yes to the Confirm File Delete prompt:


    6. If your scanner uses EPSON TWAIN, escndv will not be listed. Instead, look for a folder called EPFB* (where * represents a number e.g. 4, or 5) and delete the EPFB* folder.

    7. Close the window. Do not delete any other files in this window.

  8. Delete scanner-specific temporary files.



    1. Open My Computer then open your hard disk drive (usually C:).

    2. Open the Documents and Settings folder, followed by the folder with your user name on it e.g. "PC User".

    3. In this folder, open the Program Data folder then the EPSON folder.

    4. Within the EPSON folder, delete the ESCNDV folder.

      Notes Icon Note:

      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).



    5. Next, click on the Tools option from across the top and select Folder Options.


    6. A window will appear, click on the View tab.

    7. Underneath Hidden files and folders ensure that the option for Show hidden files and folders is selected and then click OK.


    8. Return to Documents and Settings and open the folder that has your username on it.

    9. Open the Local settings folder.

    10. Open the Temp folder and look for the following files:

      Twain.log
      Twainxxx.MTX
      Twunkxxx.MTX


      '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.


    11. Delete the Twain.log, Twainxxx.MTX, Twunkxxx.MTX files from the folder. Close all windows back to the Desktop and restart the computer.

    Back to Top


  9. Once the computer has restarted, empty the Recycle Bin.

    • Right-click the Recycle Bin icon on the Desktop. A menu appears; left-click on Empty, or Empty Recycle Bin. Click Yes to the prompt to delete the items in the Recycle Bin.

  10. Make sure your scanner is still powered off and disconnected from the computer.

  11. The Epson scanner driver is now uninstalled.

    If you need to reinstall the driver, do so using either the original CD-ROM or using the latest driver from the Epson Support website.
