General Scanning Tips

16-bit versus 32-bit applications:

Image Pals 2 GO! - the image editing software and InfoCenter the scanning control software included with the ImageReader Express scanner- are both16 bit applications. 16 bit applications are supported by Windows 3.1x and Windows 95.

Selecting the correct source:

Before attempting to scan with your ImageReader Express scanner you need to select the source from which you are scanning. To select your source click on File> Select source or File>Acquire>Select Source (depending on the application you are scanning with). If you will be scanning into a 16 bit application such as InfoCenter or Image Pals 2 GO! image editor you should select the Flatbed (16) choice in the “source” dialog box. If you are scanning with a 32 bit application such as Adobe Photoshop you should select Flatbed (32). If you do not select the correct source you may receive an error message when attempting to scan or run into complications when trying to transfer your scanned image.
