[sane-devel] Perfection 610: cannot scan in color

2013-01-10 Thread Evil Mr Henry 
The -y 297.18 (not --br-y) command works. Thanks for your help.

 Shouldn't that be --mode Color, with a capital C?

 (It is, in fact, an Epson Perfection 610 USB scanner.)

 This is a new computer; the scanner worked on my old computer in much
 the same setup.

 What version of sane backends and which backend did you use there?

 Running Mint (Ubuntu) 64bit, Sane 1.0.22-7ubuntu1

 The following is the output after setting export SANE_DEBUG_EPSON2=255:

 scanimage -v --mode color -d epson2:libusb:003:005 --format png 
 outfile.png

 I've gone through the log and it's clear from that that this is a bug in
 the epson2 backend.  It fails to take into account the line distance
 when computing the maximum scan area, leading to a maximum that is too
 big.  You can work around the issue by using --br-y 297.18 (i.e. 11.7
 inches).

 Hope this helps,

Also, for anyone else with this problem, this works in XSane when I set 
the scan size to DIN A4 port.
