I have 76001 Plustek with Silverfast 6.6.
I do not habe a focus button so cannot focus.

Dear Customer,

the Plustek 7600 does not feature a Manual Focus.
The Button is just present when the Scanner has this feature.

In fact that scanner does not have autofocus either. It has a fixed-focus lens. If you think your scans are out of focus, you are pretty much out of luck unless you can locate a third-party film/slide holder that holds the film in a different plane.
