Hi, I know nothing about ColdFusion. However what you explain sounds like something that can be easily caused by the internal structure of your input files. I once created a sample to show a similar problem here:
http://sourceforge.net/mailarchive/message.php?msg_name=46101A8D.9080204%40t-online.de The example there shows that the content of the inputfile can influence in what way other parts of the created file are displayed. It does not solve your problem but shows how such things can happen. The solution would be to save the graphics state before and restore after you change the state. In your case you might be able to preprocess your files to embed each page in another page of the same size while doing this (saving and restoring graphics state). Most probably there is not only the scanned bitmap in your scans. Your scanner software might add some text to the scans even if it is invisible. After the first page (because of using getovercontent) the graphics state or your text settings change.
