Before you
connect your thumb drive or device, make sure the product is turned
on but not printing.
Note: Epson
cannot guarantee the compatibility of your drive.
When you
finish printing, 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 drive or turn off
the product when the access light is flashing, or you may lose
photos on the drive.
