1 Introduction
Kodak i800 Series Scanners
The i800 Scanners are high-volume
production scanners which include
image processing technology that
can improve image quality and
sometimes make the reproduction
better than the original.
You can use the ISIS Driver or
TWAIN Data source (both are
available on the CD that is included
with the scanner) or Kodak Digital
Science Capture Software to enable
image processing.
Other popular scanning applications are also compatible with these
scanners, however, these applications may not be able to access all of
the image processing options. Please refer to your application vendor’s
documentation for specific information.
The features Four configurations of the i800 Series Scanners are available.
♦ Kodak i810 Scanner (bi-tonal) provides bi-tonal scanning with
throughput speeds up to 120 ppm.

Image outputs i800 Series Scanners can return bi-tonal, grayscale or color images to
the host. Below is a description of the valid combinations.
All i800 Scanners are duplex scanners. This means both the front and
the rear side of each document may be captured. For each side
captured, the scanner creates a bi-tonal/binary only (i810/i830) or a
bi-tonal/binary and color/grayscale (i820/i840) image. The host
application controls which of these images is transferred to the host to
be stored as an image file. For example, for an i840 Scanner if all four
images are returned to the host, the following four files could be created:
• Front bi-tonal/binary: FB.tif. This image file represents the
contents of the front side of the document using one-bit per pixel.
• Front color: FC.jpg. This image file represents the contents of the
front side of the document using 24-bits per pixel.
• Rear bi-tonal/binary: RB.tif. This image file represents the contents
of the rear side of the document using one-bit per pixel.
• Rear color: RC.jpg. This image file represents the contents of the
rear side of the document using 24-bits per pixel.
NOTE: Actual file formats are determined by the host application.
Through the application these image files can be controlled
independently.
FB.tif (front bi-tonal) FC.jpg (front color) RB.tif (rear bi-tonal) RC.jpg (rear color)

Another example of a simultaneous output where all four images are
returned to the host would create the following four files:
• Front grayscale: FG.jpg. This image file represents the contents of
the front side of the document using 8-bits per pixel.
• Front bi-tonal/binary: FB.tif. This image file represents the
contents of the front side of the document using 1-bit per pixel.
• Rear grayscale: RG.jpg. This image file represents the contents of
the rear side of the document using 8-bits per pixel.
• Rear bi-tonal/binary: RB.tif. This image file represents the contents
of the rear side of the document using 1-bit per pixel.
NOTE: Actual file formats are determined by the host application.
These image files can be controlled through the application
independently.

grayscale)
FB.tif (front
bi-tonal/binary)
RG.jpg (rear
grayscale)
RB.tif (rear
bi-tonal/binary)

2 Best Practices
This chapter provides you with recommendations for program
logic, which will allow you to interact efficiently with the i800
Scanner. This high-level information is not intended to be used
as a coding guide. The following information is provided in this
chapter:
• Basic image capture
• Controlling image transfer order – switching between
color/grayscale and bi-tonal
• Jam recovery
• Image file storage locations
• Bar code recognition
• Starting image addresses
• Controlling print strings
• Electronic Color Dropout (form design, drop-out colors)
• Available image header information and its uses
• Zone processing (recombining images, especially for viewing)
• Programmable keys
• Patch reading
• Batching
NOTE: The term host in the sections that follow refers to either the
driver or application depending on code logic.
Basic image capture Basic image capture is the high-level logic flow for retrieving images
from the scanner.
Follow this sequence to scan documents: set up the scanner,
enable scanning, initiate polling, feed documents and disable
scanning.

Scanner setup To set up the scanner:
1. Set up your scanner operating conditions:
• simplex/duplex
• starting image address
• image order
• lamp timeout
• transport timeout
• transport timeout response
• length detection status and response
• multi-feed detection status and response
• page-on-demand or batch count mode
• starting document count
• batching parameters (batch level, count, start and
end-of-batch functions)
• patch parameters (patch types to recognize, transfer patch
definition)
• printing parameters (printing status, print font, orientation
and strings)
• programmable keys
• level to follow level rules
• confirmation tone
• image address formats
For information on programming these conditions, see Chapters
3 or 4 (depending on your driver). For other vendor tool kits, refer
to their documentation.
2. Select your Color table as appropriate for color document
scanning. See Chapters 3 or 4 (depending on your driver).
For other vendor tool kits, refer to their documentation.

3. Determine if any changes to the Image Processing
parameters need to be made for the current application.
NOTE: This check needs to occur for up to four separate images
from the six available options depending on your
application: Front Color, Front Bi-tonal, Front Grayscale,
Rear Color, Rear Bi-tonal, Rear Grayscale.
Image Processing parameter changes remain in effect until
one of the following conditions occur:
• The scanner is powered down using the power switch.
• A SCSI bus device Reset command is executed.
• New imaging parameters are sent from the host.
4. It is recommended that you calibrate the scanner. For
procedures on how to do this, see the Kodak i800 Series
Scanners,User’s Guide.
5. Prepare documents according to the instructions found in the
Kodak i800 Series Scanners, User’s Guide.
Enable scanning The host must issue a Scan command to enable scanning before
documents can be transported through the scanner. If scanning has
not been enabled, the feeder and transport system will not turn on.
Initiate polling Initiate host system polling of the scanner to ensure scanned
document images are transferred from the image buffer to the host
system. Polling should continue until scanning is disabled.
For more information see the sections entitled, “Controlling
image transfer order” and “Image header information” later in this
chapter.
Feed documents Feed documents according to the instructions found in the Kodak
i800 Series Scanners, User's Guide.

A-61510 January 2005 2-4
Disable scanning Scanning is disabled to allow the host to download configuration/
setup changes between jobs and to handle certain types of errors.
Scanning is also disabled when one of the following conditions
occur:
• The scanner is first powered on using the power switch.
• A SCSI bus device Reset command is executed.
• An End-of-Job indicator is sent by the operator from the operator
control panel.
• A scanner-unique End-of-Job command is issued by the host
computer.
• An error occurs requiring fault recovery.
NOTE: When scanning is disabled, documents cannot be scanned
until the host enables scanning.
Error handling The scanner recognizes and reports a variety of error conditions.
Some errors are reported to either the host (via the SCSI interface) or
the operator control panel, while others are reported to both the host
and the operator control panel.
An error (via the SCSI interface) is defined as either a current or
deferred error.
A current error results from a problem in processing the current
SCSI command. This can include sending an invalid command,
trying to read from an empty image buffer, or an end-of-job
condition. Since one or more errors may be pending at any time,
current errors are reported first.
A deferred error results from an error condition within the scanner,
such as a document jam. Deferred errors that may have occurred
are reported after current errors.
NOTE: Low level SCSI commands and information will be handled
by your device driver. The following information is provided
for reference only.
