Dear Sirs, I want to change the glass in the TMA module, because of the scratch. When I scan films it often leaves its track on the image. See the sample. Please send me info about the glass, which is used in the TMA module for Scanjet with regulatory model GRlyb-0311, serial number Q3121a [Personal Information Removed]. I cleaned the TMA from external side according to the instructions in the manual. No use. Please also write, if change the glass for other kind of it can help. What glass should be used. It is rather hard to find the TMA module in my country and takes a lot time to deliver from abroad. The arrow on the photo shows the track. Look the sample image on the link.
