Sometimes parts of the original document are not scanned correctly and are missing from the image.

1. Check you are using the correct TWAIN driver to scan with.  As you are starting the scan choose the 'Settings' button and make sure the correct driver is selected.
   
   
2. Update the scanner driver.  Go to the scanner manufacturers website and download and install the latest version of the driver.
   
   
3. Is the correct paper dimensions specified in the Settings area? 
   Left=0; Top=0; Right=11; Bottom=29.7
4. Try changing the Paper Size to 'None' (I know it is odd but sometimes this does work)
5. Use the 'Transfer images in Native mode' (especially with Brother MFC scanners)
   
   
6. Use a third-party application such as Irfanview to scan some documents.  Often this appears to change some low-level settings to reset the correct size of the scanned image.
   Alternatively use the dwgdemo.exe file from the zipped suite of TWAIN test applications.  Download from here.
   
   
7. Exit from SPM or PHM, start up and try scanning the diocument again.
   
   
8. If still no success submit a support ticket to the Incisive Helpdesk
