Correct Procedure for Deleting Epson Scan Driver:

! Use the driver specifically written for your scanner model to uninstall the Epson Scan

driver.

! If you have more than one Epson scanner model on your computer, use the driver

specifically written for each scanner to uninstall its respective device driver.

! If upgrading from a Power PC-based Epson Scan driver to a Universal Binary driver,

first delete the Power PC driver using only the Power PC driver for your scanner model.

Then install the Universal Binary driver.

If the above procedure does not resolve the problem, then manually verify that the Epson

Scan files and folders, listed below, have been deleted.

! EPSON Scan (in Applications Folder)

! EPSON*********.ds (****** = scanner model)---located in the Library / Image Capture /

TWAIN Data Sources folder
