Disabling of the internal Light Source of Epson 1680 sane-epson 2
i own a Epson 1680 Pro without TPU. I want to build my own TPU to scan
negatives. The Problem is the main light source of the scanner must be
disabled and the focus point must be set to : right above the glas.
Is there a way to disable the internal light source while using the
scanner in the flatbed mode?
