LaserSoft Imaging

hi,
i am getting these streaks/bands when scanning reflective/prints. the scanner is a 10000xl.
i have tried calibrating but it hasn't helped.
thanks
please find attaced scan to illustrate the problem.

Dear customer,

such lines originate directly in the scanner.
This could be dirt on the sensor or another optical component.

kind regards,
Arne Ketelhohn.
