How to fully remove a scanner from Windows


  • I am still unable to scan to the computer.
  • 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 remove the Epson scanner driver if you simply wish to remove 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.

Notes Icon Note:

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.

If you have an Epson printer or All-In-One and you can no longer print after following this procedure, see the following articles and then reinstall the driver using the latest driver from the Epson website. Refer to the following article for more infomation.

Follow the steps below to fully uninstall the scanner driver from Windows.

Start with the scanner powered on and connected to the computer.

Delete the OEM Files

  1. Open Windows Explorer or Computer.
  2. Navigate to the drive that Windows is installed on (usually C:).
  3. Open the windows folder.
  4. Open the inf folder.

    Notes Icon Note:

    If you cannot locate the inf folder, click on  start and type 'Run' into the Start Search box. (Or hold  Windows logo key + R.). Type inf into the blank Open: box then press Enter.

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

  7. There are normally two oem files that share the same number. For example with oem0 there would normally be oem0 and oem0.PNF.

    oem.inf file:    oem.PNF file: 

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

    Notes Icon Note:

    You cannot open a .PNF file.

  9. Double-click on the file and it will open in the Notepad program.
  10. Check for 'SEIKO EPSON' or 'EPSON' within the first few lines of text.
  11. If it does not list '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.
  12. 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'.

  13. 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, oem40.inf is a SEIKO EPSON file. This should be deleted along with oem40.PNF.

  14. Continue to check each OEMxx.inf file in turn, following the procedure above.
  15. Once all OEMxx.inf files have been checked, close the inf folder.

Delete escndv Folder

  1. Open Local Disc (C:) again and open the Windows folder.
  2. Double-click on the yellow twain_32 folder.
  3. If there is a folder called escndv, right-click on the escndv folder and left-click on Delete.

    Notes Icon Note:

    If escndv is not be listed, look for a folder called EPFB* (where * represents a number e.g. 4, or 5) and delete the EPFB* folder.

  4. Click Yes to the Delete Folder prompt.

    If you receive a Windows confirmation request, click Continue.

  5. Close the window. Do not delete any other files or folders.
  6. Open Computer then open your hard disk drive (usually C:).
  7. Next, click on the Organise option from across the top of the window and select Folder and Search Options.

  8. A window will appear, click on the View tab.
  9. Underneath Hidden files and folders ensure that the option for Show hidden files and folders is selected then click Apply and OK.

  10. Open the Users folder, followed by the folder with your user name on it e.g. 'PC User'.
  11. In this folder, open the AppData folder then the EPSON folder. If not listed here open the Temp folder within the AppData folder, followed by the EPSON folder.
  12. Within the EPSON folder, delete the ESCNDV folder.

    If you have an scanner which pre-dates Vista (i.e. released prior to 2007) and have installed the software from the original CD-ROM, an ESCNDV folder will not be listed - look for and delete the EPFB* (where * represents a number e.g. EPFB5).

Delete TEMP Files

  1. Return to Users and open the folder that has your username on it.
  2. Open the Local folder.
  3. 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.

  4. Delete the Twain.log, Twainxxx.MTX, Twunkxxx.MTX files from the folder. Close all windows back to the Desktop and restart the computer.
  5. Once the computer has restarted, empty the Recycle Bin. Right-click the Recycle Bin icon on the Desktop. A menu will appear; left-click on Empty, or Empty Recycle Bin. Click Yes to the prompt to delete the items in the Recycle Bin.
  6. Make sure your scanner is still powered off and disconnected from the computer.
  7. The Epson scanner driver is now uninstalled.

If you need to reinstall the driver, we recommend using the latest driver from the Epson website

Refer to How to download drivers and software from the Epson website for more infomation.
