The Lexmark X3300 is unsupported by SANE. Its not even listed in the 
supported devices <http://www.sane-project.org/sane-mfgs.html> web page.

You could write your own driver, or make a request on this list that 
someone write one. I wouldn't hold my breath trying to get someone to 
write one. Its very difficult for the writer unless he has the exact 
same model for testing. Also, Lexmark is very close mouthed about their 
scanner technology, so the writer needs to do a lot of scans on a 
Windows machine using the Lexmark Windows driver and log the usb 
transfers and reverse engineer the backend from the log files.

Two vague ideas (if the green line is vertical):

- defective sensors (maybe a quality calibration would help a bit)
- dirt on the calibration stripe or windows. Even a small dark spot on
  the area where shading correction is done could have a big impact, as
  it gets applied over and over for the whole scan height.

Especially because you mentioned that the higher the resolution the
wider the line. I would suspect a physical cause then.
