Disturbing line for Canon FS4000US

[gushan]

I am using a demo version 6.5. Frankly speaking, the scanning result is much better than v**s**n, especially details. However, every time, there is a thin colorful line across the picture. Who knows what's wrong with it? Is it a compatible problem? Will a non-demo version solve it?

Dear gushan

thank you for your interest in LaserSoft Imaging's software products :)
This line is not a "feature" of a demo version. It could be a defitive CCD element, it could just be dust. Please trying cleaning your scanner with a pressure air can.

Best regards
