Cannot adjust margins to original settings

[FlamingoMSF310]

Words for Mac 2011. I submitted a books to a publisher 228 pages. When printed the publisher lets you approve the print by posting it on line. I did and sent for a bounded printed copy. When I scanned the copy on line I failed to notice the margins.
The printed copy was not Justified and the length of the sentances had gone
from approx. 4" to 3". Disaster. I have been hours trying rectify the margins.
No I did not make a copy before sending to publisher. The only copy I have now
is the copy sent to me by the publisher. Do I have to retype the whole book?
I sure could use some help. Thank you
