Ok, so far as we have now 2 scans that was made in the same conditions... I try to explain. There are two types of scanners thas have different image sensors: CIS-type and CCD-type. There is a few significant differences between them (it was described at the upper link, and CCD much better than CIS), and one of them is Depth of field. CCD-type uses most of Depth of field than SIC, that is: CCD-type can scan a page situated over the CCD-scanner's glass, whereas for CIS-type is necessary maximum fit of a page to the CIS-scanner's glass.
So the reason of this larger blurry area is a type of your scanner: it's CIS. My scanner is CCD, which is why our results of scanning are so different.
Idk how to help with it. =( I tried to find a method to taking a better scan for CIS-type of scanner, but mostly sites said "use a flat pages, take apart your book, or use CCD".
...You may completely ruin the book if you continue to scan with maximum pressing. ((
