A-61517 October 2004 1-1 1 Introduction Kodak i100 Series Scanners The Kodak i100 Series Scanners are low-volume production scanners which include image proce ssing technology , can improve image quality and sometimes make the reproduction better than the origi nal.
A-61517 October 2004 1-2 About this manual This manual provides the following: Chapter 1, Introduction includes a brief summary of the Kodak i100 Series Scanners, a list of features available for each scanner and the support d rivers.
A-61517 October 2004 1-3 Image output s i100 Series Scanners can return bi -tonal, grayscale or color imag es to the host. Below is a description of the valid combinatio ns. The i150 Scanner is a simplex scanner . This means that only one side of the document may be captured.
A-61517 October 2004 1-4 These image files can be controlled thro ugh the application independently . FB.tif (front bi-tonal) FC.jpg (front color) RB.tif (rear bi -tonal) RC.jpg (rear color) Another example of a simult aneous output where all four images are returned to the host would create the following four fil es: • Front grayscale : FG .
