I am using the same scanner for a long time : EPSON PERFECTION V500 PHOTO.
I can’t say from when I it is not working as expected.
Both last and previous software version run into the same problem.
Changing Epson driver to old avasys driver is without help.
Presently, after returning to previous version by deleting the driver, and deleting xsane, and then reinstalling previous driver and previous xsane :
user_test@linux:~> rpm -qa | grep iscan iscan-data-1.14.0-1.noarch iscan-2.28.1-3.x86_64 iscan-plugin-gt-x770-2.1.2-1.x86_64 user_test@linux:~> rpm -qa | grep sane xsane-0.998-8.1.2.x86_64 user_test@linux:~>
For the following I can’t say if it belongs to that previous version.
With the three kind of driver :
If I scan a document, and ask for b/w document, the generated pdf file is OK.
If I scan a document, and ask for color document, the generated pdf file is OK.
If I scan a document, and ask for gray scaled document, the generated pdf file is bad ( duplicate image in one ), but the document showed in the viewer is OK.
Help is welcome.
