[sane-devel] lamp on Epson Perfection 1650 never turns off]

[Karl Heinz Kremer]

Where did you find information about the option commands that you
put into epson.conf? These commands are interpreted as additional
scanners, and because you don't have any devices named "option warmup 
30",
they are ingored.

There are no commands to turn of the lamp for the EPSON scanners that
use the ESC-I command set (pretty much any EPSON scanner with the
exception of Perfection 660, 1250 and 1260).

The lamp should automatically be turned off by the scanner.
