Diagnostic Software (for use by Kodak Service Personnel)
Robust diagnostic software for the i780 Scanner provides maximum uptime and optimum
performance for the customer. Comprehensive hardware analysis and problem determination in
the software allows a high success rate in resolving the root cause of problems via remote
analysis. When on-site service is required, the diagnostic analysis allows the Field Engineer to
better understand the nature of the problem and be prepared with the appropriate service parts
before going on site.
Features of diagnostics include the ability to provide error logs that can be e-mailed or faxed to
the Response Center at Kodak for further analysis.
Optics
The design heritage of the M-type Kodak lens used in the i780 Scanner comes from a high-
resolution production scanner developed for complex character scanning. The lens also
incorporates an infrared filter with its lead-free multiple elements. This reduces light loss
and eliminates alignment of the infrared filter to the lens. The infrared filter reduces warm-up time
by providing a more “color stable” light output to the CCD when the lamps have just been turned
on, as well as during operation.
Unlike competitive scanners, which use off-the-shelf lenses, the additional glass elements in the
i780 Scanner’s lens provide a greater depth of focus to keep thin-to-thick and light-to-heavy
documents in focus. In addition, the scanner’s lens keeps outer edges in focus so they have
virtually the same clarity as the center of the document.
Tri-Color Plus Array
The Tri-Color Plus Array is built on a rich foundation of Kodak CCD technology. Produced by the
Kodak Image Sensor Solution division (ISS) via specifications created by Kodak’s Document
Imaging Scanner Engineering and Advanced Development teams, the Tri-Color Plus Array is the
fastest, most accurate and advanced chip available today. This CCD is exclusive to Document
Imaging.
One array contains the red, green, blue and luminance (grayscale) sensors. This provides cleaner
image transmission (focusing the lens on one array), and since the grayscale image is created in
conjunction with the color image, you have the ability to use grayscale image elements in the
color image processing chain for a sharper image and to maximize image purity in dark regions of
the image.
