This section compares the
Kodak
i780 Scanner with the major competition in the mid-volume
production scanner segment. We hope you find the comparisons useful.
The information that follows was gathered through sell sheet materials supplied (physically or via
the Internet) by the manufacturer. Other data has been provided by Kodak Engineering Staff,
Value-Added Distributors, and outside consultants. Several categories of information require
special explanation for a full understanding of the following competitive profiles.
NOTE: Every effort has been made to verify the features, performance, and pricing information
shown on the following pages. As conditions change, however, Kodak cannot accept
responsibility for the validity of competitive data.
Scanner Speed
All manufacturers have provided the stated speed(s) of their paper transports (typically using the
landscape mode on A4 or letter-sized paper). Be
extremely cautious
using these figures, as very
few, if any, scanners can actually function at these speeds due to constraints in paper handling,
jams, or restrictions at the computer (SCSI/Video/USB/IEEE-1394) interface.
Kodak scanners perform all functions at rated speed, with no performance penalty for color
imaging, Perfect Page processing and our new auto orientation/auto rotation feature. Not all (if
any) of the competitive scanners can make this claim.
Capture Resolution/Output Resolution
The basic laws of physics suggest that higher output resolution for a given machine means
proportionally slower speed. Additionally, the differences between capture and output resolutions
allow the imaging algorithms within the scanner to clean up the image and remove spurious data.
Therefore, capture resolution plays an integral part in establishing the overall quality of the image.
Capture resolution is the actual dpi of the image as the scanner captures it. Some scanners can
interpolate up to a higher output resolution than the optical or actual capture resolution (i.e., a 300
dpi image can be interpolated up to look like a 600 dpi image). Final image quality is dependent
on multiple variables, such as the quality of the lens, light, CCD, and image processing routines.
