Unless you have changed the default wrapping style for inserted/pasted
objects, it will be inserted In Line With Text, which means that it will
have to conform to the page margins. If what you've copied is an entire
page, then you need to expand it to fill the Word page. Click on the image,
which should display the Picture toolbar. Click on the dog icon to get the
Text Wrapping menu and change the wrapping to, say, In Front of Text or
Behind Text. Then go to Format Picture | Size and change the size to 100%.
You may need to then drag the picture to align with the page.
