How books get scanned.

My dumbass always pictured an old librarian with gloves at the copy/scanning machining having to redo it over and over because it scanned crooked.

@Ask_aubry my head can’t wrap itself around how this thing scans both side of the page
@DistrictDave01 @Ask_aubry I think it's pulling in two pages at the same time, so each page gets drawn up twice, first on the right, and then on the left.
