Glass copy problem.

[Exedian]

Hello, this is the first time I am writing. thanks to you I have solved several problems. Today I have a particular problem only with the glass copy. the print is fine, in the ADF the copy seems acceptable, but when I go to do the glass copy these spots pop up. surely I will go to change the ccd. but I want your opinion.

have you performed the standard background data reset and stabilize? then all 9 or 12 gradations?
the 1st sample looks like a crooked scan bed.
just covering the basics first before using metal tools

Adjustments have been made, but it has not solved anything. investigating the glass tied to the laces turns out to be crooked. For now we are proceeding with the warranty, the owner told me not to waste time.
