I am now writing a thesis which is required to have 1 and half inches on the left or binding side, and 1 inch on the other three sides.

I just have my print-out checked in the binding office and I was told the margins are not okay, especially the one on the top is not enough, a little less than 1 inch. See the figure below:

I wonder which commands are responsible for the margins on the four sides, especially for the one on the top? I provide links to two files I believe that control the layout and format of the thesis:jhu12.clo and thesis.cls.

Or instead of modifying the LaTex files, is thre some setting when printing the pdf file to control these margins on the print-out?

Thanks and regards!

EDIT:

This is the print-out of command \layout

It shows "one inch + \voffset" for the top (the NO. 2 item). But the staff at the binding office use his ruler to show it is less than 1 inch. How to adjust the margins in LaTex then?

Thanks!
