To save
scanned images on a USB thumb drive or other USB device, you must
first connect the device to your product.
Note: Epson cannot
guarantee the compatibility of your drive.
When you
finish scanning, make sure the access light on the drive is not
flashing, then remove or disconnect it from the product.
Caution:
Do not remove the USB thumb drive or cable
when the access light is flashing, or you may lose data on the
drive.
