The Least Comfortable Solution

Since the current situation is that Silverfast 8 has issues with serious contrast shifts when scanning in higher resolutions in Mac, I resorted into the least comfortable solution; installing the software in Windows 7. Luckily I have Windows 7 installed on bootcamp partition.

According to Silverfast support, apparently the contrast does shift in Windows 7 version of the software as well but it is less dramatic.

They told me that the new version of the software (which should have the issue fixed) will be released in first days of 2013.

Now, looking forward how scanning in Windows 7 goes.

Response from Silverfast

I got following response from Silverfast regarding the various issues I have had with Plustek Opticfilm 8200i and Silverfast 8. It appears that presently there is no solution other than getting updated driver framework if you are in Mac OSX.

I do feel disappointed because currently there is nothing I can do but wait and the + 50,000 yen scanner is sitting as a paperweight.

I do have to say that the support from Plustek has been excellent though, but if the issue is in the drivers..

Dear Mr. Saari,

like you suspect, this issue is indeed driver related. We are in close contact with Plustek
and are working together with them to get a new framework for this scanner model.

As soon as the new frameworks are implemented, we are going to bring an update that is
resolving this issue. 

Kind regards,
