This article explains how to fully remove the Epson drivers for your All-In-One. You can use this procedure if you simply wish to remove the Epson software from your system, or to try to resolve a problem you are experiencing.
However, if you have been experiencing difficulties printing from or scanning to your computer then there may be a communication issue. Ensure that you have followed the troubleshooting article that addresses the issue you are experiencing, and then use the procedure in this article if the issue remains.
Power off the All-In-One and disconnect the USB cable.
Uninstall the printer driver and Epson Scan from Add or Remove Programs.
Click on the Start menu, then Control Panel.
Open Add or Remove Programs.
Locate and click on EPSON Printer Software. A size will not be stated, this is normal.
Click on the Change/Remove button.
The EPSON Printer Utility window will appear.
Click on the Epson printer icon that corresponds to the printer you wish to uninstall and click OK.
Answer Yes to all prompts to complete the uninstall process.
Click OK to the "Uninstall complete" notification.
Repeat this procedure until all Epson printer drivers are uninstalled.
Once complete, remove EPSON Scan from Add or Remove Programs.
If EPSON Scan is not listed, look for EPSON TWAIN 5 instead. If EPSON TWAIN 5 is listed, click on it in the list to highlight it then click on Change/Remove.
Click on EPSON Scan in the list then click Change/Remove. If you are asked to restart the computer at any point, choose "No".
Once the uninstall program has finished, close Add or Remove Programs.
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 inf folder.
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 theclose icon found in the top-right of the program window.
If "SEIKO EPSON" is listed within the first few lines and the printer 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'.
Next, click on the Tools option along the top of the screen and select Folder Options.
The Folder Options window will open. Click on the View tab.
Beneath Hidden files and folders ensure that the Show hidden files and folders option is selected and then click OK.
Open the Application Data folder then the EPSON folder.
Within the EPSON folder, delete the ESCNDV folder. Note: If your All-In-One uses EPSON TWAIN, an ESCNDV folder will not be listed - look for and delete the EPFB* (where * represents a number e.g. EPFB5).
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.
