... That the scanner a scanning distance from the edge (Silver strips side) has and starting exposure of about 14mm, the rebate of most books but is up to beginning of the line of writing only about 9 mm - the means of each line missing 5mm Scripture.
Otherwise all ok. if you want to scan a few pages of a book. Therefore, only two stars.
Also important is the uniform straight pulling the scanner.
