How to get the film hider to scan 4 negs in auto mode?

[WATony]

I have a OpticFilm 8100 with SilverFast SE Plus v 8.0.1r38 installed on an iMac, but I can't find how to get the film holder to scan more than 1 neg or slide at once.
I can't find any reference in the manuals, but I can see a Batch Scan option.
Is that what I use and is there a reference to any tutorial on its use?

I want it to scan a whole filmstrip or set of slides without changing each one.
Is this possible on a Mac?

Thanks

Dear customer,

The Plustek 8100 has no possibility to move the film holder on it's own.
Therefor it can only do single scans.
Batch mode is not supported for this device.

kind regards,
Arne Ketelhohn.
