When I open some pdf files I just get a gray page. Not all files, just some. However, if I print the document it prints OK. Is there some setting that causes this issue? I have version 10.1.2 Adobe Reader X.
Go to Edit>Preferences>Page display>Page content and information and be sure the "Show large images" box is checked.
The PDF's that are gray are probably scans, or in other words large images.
That fixed it. Thank you. Another agony solved. Now on to my printer problem.
