neither LSI testing center not Microtek engineer could reproduce the problem presented above with the AS120 with firmware 1.70.
However, it does happen with the SS120 (along with a colour channel mismatch) with the firmware 1.33, but the very same scanner!
Are there no chance in ever getting an updated firmware from Polaroid, you will have to <a href="https://www.silverfast.com/forum/viewtopic.php?p=13887&highlight=#13887">see if Microtek can help you</a> with providing appropriate firmware EEPROMs.
However, this one is not for the faint at heart...

Please note that the customer sbosman stated on phone that he experienced this problem can be solved by using a colour filter (can be activated in >Options >Special) when scanning in greyscale mode, too.
