1 Introduction
The Kodak i1800 Series 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 Datasource (both are available
on the CD that is included with the scanner) or Kodak 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 vendor’s
documentation for specific information.
The Kodak i1800 Series Scanners provide both color/grayscale and
black and white scanning simultaneously with throughput speeds up to
200 ppm.
About this manual This manual provides the following:
Chapter 1, Introduction includes a brief summary of the Kodak i1800
Series Scanners.
Chapter 2, Best Practices includes information to use when setting up
applications, recommendations on how to handle jam recoveries,
image addressing information, controlling print streams, electronic color
drop-out and much more.
Chapter 3, Using the TWAIN Datasource includes information on using
the dialog boxes presented by the TWAIN Datasource and an
explanation of the fields on each tab.
Chapter 4, Using the ISIS Driver includes information on using the tabs
presented by the ISIS driver and an explanation of fields on each tab.
Appendix A, TWAIN Image Processing Terminology — the TWAIN
Datasource for the Kodak i1800 Series Scanners have been updated to
include new terminology for traditional Kodak image processing
functions. See this appendix for a comparative chart to map between
terms.
NOTE: The scanned images used in this guide were selected for the
challenges presented to a typical scanner due to the low-
contrast characteristics of the images.

1-2 A-61580 November 2007
Image outputs The i1800 Series 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 black and white and color/
grayscale image. The host application controls which of these images is
transferred to the host to be stored as an image file.
The Kodak i1800 Series Scanners can return black and white,
grayscale or color images to the host. Below is a description of the valid
combinations.
•Front black and white: 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.
•Back black and white: BB.tif. This image file represents the
contents of the rear side of the document using one-bit per pixel.
•Back color: BC.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.
These image files can be controlled through the application
independently.

A-61580 November 2007 1-3
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 black and white: FB.tif. This image file represents the
contents of the front side of the document using 1-bit per pixel.
•Back grayscale: BG.jpg. This image file represents the contents of
the rear side of the document using 8-bits per pixel.
•Back black and white: BB.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.

2 Best Practices
This chapter provides you with recommendations for program logic,
which will allow you to interact efficiently with the i1800 Series
Scanners. 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
• Switching between color/grayscale and black and white
• Jam recovery
• Image file storage locations
• Bar code recognition
• 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
• Starting image addresses
• Patch reading
•Batching
NOTE: The term host in the sections that follow refers to either the
driver or application.
Basic image capture Basic image capture is a 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.

2-2 A-61580 November 2007
Scanner setup To set up the scanner:
1. Set up your scanner operating conditions:
• simplex/duplex
• image order
• lamp timeout
• transport timeout
• transport timeout response
• length detection status and response
• multi-feed detection status and response
• starting document count
• printing parameters (printing status, print font, orientation and
strings)
• programmable keys
• batching parameters (batch level, count, start and end-of-batch
functions)*
• patch parameters (patch types to recognize, transfer patch
definition)*
• starting image address*
• level to follow level rules*
• image address formats*
*These items are only available when Image Addressing is enabled.
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 Document Type/Color Correction 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 Black and white, Front
Grayscale, Back Color, Back Black and white, Back
Grayscale.
Image Processing parameter changes remain in effect until one of
the following conditions occur:
−The scanner is powered down using the power switch.
−New imaging parameters are sent from the host.
4. Prepare documents according to the instructions found in the Kodak
i1860 User’s Guide.

A-61580 November 2007 2-3
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 i1800
Series Scanners User’s Guide.
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.
• An End-of-Job indicator is sent by the operator from the operator
control panel touchscreen.
• 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 or the touchscreen, while
others are reported to both the host and the touchscreen.
An error is defined as either a current or deferred error.
A current error results from a problem in processing the current
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 commands and information will be handled by your
device driver. The following information is provided for reference
only.
When an error occurs, the host will receive a Check Condition Status.
This indicates to the host that there may be one current error and
potentially one or more deferred errors. The host must follow a Check
Condition Status with a Request Sense command. The Sense data will
indicate the type of error that has occurred.

2-4 A-61580 November 2007
To receive subsequent pending errors, the host must execute a Test
Unit Ready command. If a deferred error is pending, the Test Unit
Ready command will terminate with a Check Condition Status. The host
follows with a Request Sense command. The combination of Request
Sense followed by Test Unit Ready must be repeated until a "good"
status is returned on the Test Unit Ready command. A "good" status
indicates no errors (current or deferred) are pending.
IMPORTANT: If at any point the host receives a Check Condition for a
command and fails to issue a subsequent Request
Sense command, the scanner will clear all (current and
deferred) Sense data.
Some error conditions disable scanning and cause the document
transport to stop. These errors are reported on the touchscreen. This is
done to prevent additional images from entering the image buffer while
allowing the host to perform fault recovery activities.
NOTE: The scanner cannot determine exactly which images were
affected by the error and which images were not.
If an error occurs that disables the scanner, the host can continue to
read images from the image buffer without enabling the scanner.
However, when the image buffer has been emptied, an error will be
generated indicating fault recovery is required. This differentiates
between an end-of-job disable and a disable caused by an error. The
operator may continue scanning documents after the host enables the
scanner.

Controlling image
transfer order
This section provides job stream examples which can be used in
scanning applications.
The host application is responsible for determining the order in which
the scanner returns images. Front images must always be retrieved
before back images.
Black and white only -
duplex
1. Prepare documents.
2. Start the scanner to do black and white duplex scanning (front black
and white and back black and white).
3. Setup the scanner to retrieve black and white images.
4. Enable the scanner and start polling.
Loop

Read color image
End loop

A-61580 November 2007 2-7
Single-stream duplex
alternating between black
and white and color/
grayscale using the
scanner Toggle patch
The Toggle patch is a type 4 patch that is used to trigger the scanner to
switch from the current image stream (black and white) to the
alternative image stream (color/grayscale).
1. Prepare documents with a patch Type 4 before and after any color/
grayscale documents.
2. Configure image processing parameters for all four images. Before
enabling the scanner, select only the front and back black and white
images to be retrieved.
3. Configure the scanner to alternate both sides when a toggle patch is
detected.
4. Start scanning.
Images will begin in black and white and will change to color/grayscale
when the first toggle patch is detected. Images will remain color/
grayscale until the next toggle patch is detected. Images of the toggle
patch sheet will not be returned to the host unless you also enable
patch reading and select the Type 4 patch.
Single-stream duplex
alternating between
black and white and
color/grayscale using
automatic color
detection
1. Configure image processing parameters for all four images. Before
initiating the scanner, select only the front and back black-and-white
images to be retrieved.
2. Enable Auto Color Detection by choosing Low, Medium, High or
Custom.
3. Start scanning.
The scanner will determine if it should return a black-and-white or color/
grayscale image based on a document-by-document analysis of the
color content.

2-8 A-61580 November 2007
Jam and fault
recovery
This section provides recommendations for application logic associated
with scanner jam and fault recovery.
If your scanner is enabled and you are polling when a document jam or
other fault occurs, use the following procedure to restart scanning.
IMPORTANT: Before beginning fault recovery, make sure all the
headers and images have been transferred from the
image buffer to the host system.
When a document jam or other fault occurs, the feeder and the
transport will stop and the scanner will be disabled.
1. When all images have been retrieved from the scanner (image
buffer empty), display the last image retrieved for operator viewing.
2. Use the image header of the last image retrieved to determine the
image address and sequential counter.
3. Use the information above +1 to seed the next image address and
sequential counter before re-enabling the scanner.
4. Instruct the operator to sort through the stack of documents being
scanned to find the document that produced the last successfully
scanned image. They must rescan all of the documents that follow
the last successfully scanned document.
5. Enable the scanner.

A-61580 November 2007 2-9
Image file storage
locations
This section provides general recommendations regarding the impact
of image file storage locations on the overall throughput of the scanner.
You can receive up to four image files per document. Decisions about
where to write these files when retrieving them from the scanner could
impact the overall throughput of the scanner. In order to prevent
overwriting data the scanner stops feeding paper when the internal
image buffer reaches two-thirds capacity. Scanning will not resume until
buffer memory reaches one-third. In order to minimize the number of
times this condition might occur, it is recommended that image files are
written to a local hard drive in order to avoid the potential overhead of
transferring files across the network to remote drives during scanning.
Bar code recognition This section provides general information about bar code recognition
and read rates.
The i1800 Series Scanners does not include a bar code accessory. The
host system provides bar code functionality. The main imaging
parameter, which may affect bar code read rates, is resolution. Either
black and white, grayscale or color images may be used for bar code
applications. Refer to your software documentation for their
recommendations and/or requirements for image quality to achieve
desired read rates.
Image addressing Image address information only applies when the scanner is configured
with Image Address enabled via the operator control panel
touchscreen.
The i1800 Series Scanners receive all image address functionality from
the host. This includes index format, starting image address, image
address format and level rules.
Image address format The image address format can be from one to four fields. Each field
may be up to 9 characters. Total image address length with delimiters is
30 characters. Each field may use level 1, level 2, level 3, and fixed
fields, and must be explicitly defined by the application. See Chapter 3
or 4 (depending on your driver) for more information.
The order of importance for the fields (from highest to lowest) is fixed,
level 3, level 2, level 1. When defining an image address, the field with
the highest importance must always be to the left. For example, F321 is
a valid format. F123 is not a valid format.
You are not required to use all four fields. If you chose to use fewer than
four fields, you must specify a field width of 0 for any unused field. 0
width fields may not be between two non-zero width fields.
When defining fields, you can only have one field assigned to each
individual level. For example, F21 is a valid format. F11 is not a valid
format.

2-10 A-61580 November 2007
Starting image address/
next image address
The host application must always seed the scanner with the starting
image address. The scanner will return the image address associated
with each image in the image header. The application can track this
image address for use in setting the next image address when
restarting the scanner.
Indexing schemes Documents are scanned to record the information in an easily
accessible form. The scanner offers the following indexing schemes:
• Single level
•Twolevel
• Two level offset
• Three level
• Three level offset
Single level indexing
When using single level indexing, the image address assigned to each
document is defined as follows:
• Field D is defined as a Level 1 field having a field length greater than
0.
For example, if you scan a book with 50 pages and do not want a
fixed field in the image address, the image address is defined as
follows:
• Field D has a field length of 2 characters and is defined as a Level 1
field.
• Fields A, B and C have 0 characters.
The first page is assigned image address 01. The second page is
assigned image address 02, and so on, through the remainder of the
book.
Any one of the 50 pages may later be located and retrieved using its
unique image address.

Two level indexing
When using two level indexing, the image address assigned to each
document is defined as follows:
• Field D (Level 1) defined as having a field length greater than 0.
• Field C (Level 2) defined as having a field length greater than 0.
For example, if you scan a book with 2 chapters (Chapter 1 has 40
pages and Chapter 2 has 60 pages) and the image address has
been defined as:
• Field D has 3 characters
• Field C has 2 characters
• Field B has 0 characters
• Field A has 0 characters
The header page for Chapter 1 is assigned image address 01.000. The
first page of Chapter 1 is assigned image address 01.001; the second
page is assigned image address 01.002, and so on through Chapter 1.
The header page for Chapter 2 is assigned image address 02.000. The
first page of Chapter 2 is assigned image address 02.001; the second
page is assigned image address 02.002, and so on through Chapter 2.
Any one of the pages may later be located and retrieved using its
unique image address.

Two level offset indexing
When using two level offset indexing, the image address assigned to
each document is defined as follows:
• Field D (Level 2) defined as having a field length greater than 0.
For example, if you scan a book with 2 chapters (Chapter 1 has 40
pages and Chapter 2 has 60 pages), and the image address has
been defined as:
• Field D has 2 characters
• Field C has 0 characters
• Field B has 0 characters
• Field D has 0 characters
The header page for Chapter 1 is assigned image address 01. The
remaining pages of Chapter 1 are also assigned image address 01.
The header page for Chapter 2 is assigned image address 02. The
remaining pages of Chapter 2 are also assigned image address 02.
Either one of the chapter header pages may later be located and
retrieved using its unique image address. Pages within a chapter may
be located and retrieved by first finding the chapter header and then
manually scrolling through the remaining pages of the chapter.

Three level indexing
When using three level indexing, the image address assigned to each
document is defined as follows:
• Field D (Level 1) defined as having a field length greater than 0.
• Field C (Level 2) defined as having a field length greater than 0.
• Field B (Level 3) defined as having a field length greater than 0.
• Field A may be defined as fixed field if desired.
For example, if you scan a book with two sections (Section 1
contains 2 chapters, each having 40 pages; Section 2 contains only 1
chapter, having 120 pages) and the image address has been defined
as:
• Field D has 3 characters
• Field C has 2 characters
• Field B has 1 character
• Fixed field has 0 characters
The header page for Section 1 is assigned image address 1.00.000.
The header page for Chapter 1 of the section is assigned image
address 1.01.000. The pages within the Chapter are assigned image
address(es) 1.01.001 through 1.01.040. The header page for Chapter 2
of the section is assigned image address 1.02.000. The pages within
the chapter are assigned image address(es) 1.02.001 through
1.02.040.
The header page for Section 2 is assigned image address 2.00.000.
The header page for Chapter 1 of the section is assigned image
address 2.01.000. The pages within the chapter are assigned image

Controlling document
level changes
The previous Indexing Scheme examples illustrated how document
levels change within a single group of documents. There are four
document image levels: 3, 2, 1, and 0.
There are several ways you can set or change the document level:
• You can change image address level on the touchscreen. Touching
the appropriate Level button increments the image address level to
Level 1, Level 2 or Level 3.
• You can send a new image address from the host PC.
• You can use the Patch Reader; feeding a document containing a
particular type of patch can change document levels.
• Starting a new batch can cause the image address level to change
depending on the application.
If you do not set or change the document level using one of the
methods listed, the document level will be set automatically based upon
the level rules (i.e., Level 2 is followed by Level 1, etc.) defined during
scanner setup.
The following diagram illustrates how document levels are set or
changed:
Generated Automatically Generated Automatically
Generated Automatically Generated Automatically
Document level information is transmitted in each image header.
Level Instruction:
Operator selects Level II using the Level icon on
the OCP or uses a patch II document (Level 1
documents are generated automatically using the
level to follow level rules).
Level Instruction:
Operator selects Level III using the Level icon on the
OCP a (Level II and I documents are generated
automatically using the level to follow level rules).
Level instruction:
Operator selects Level III using the Level icon on the
OCP or uses a patch III document (Level II and I
documents are generated automatically using the
level to follow level rules).
Level Instruction:
Operator selects Level II using the Level icon on the
OCP (Level I documents are generated automatically
using the level to follow level rules).

Level rules Level rules are an automated way to control document image
addressing based on the level of the previous document. For a level 3
indexing scheme, the application must define the Level to Follow Level
rules for Level 3, Level 2, and Level 1 For example:.
Level to follow level rules are used to automatically drop to a lower
level. Returning to a higher level is generally done through patch or
application control of the next image address.
Controlling print strings Full control and access to the scanner’s print string functionality is
available to the host application. In addition, the print string information
is returned to the host in the image header.
Print string formatting • Maximum character length 40.
• Character set full alphanumeric, including special characters.
NOTE: To view Japanese characters correctly you must get the MS
Gothic font set by installing the Microsoft Global IME 5.01 for
Japanese – with Language Pack, English Language Version
which can be found at http://www.microsoft.com/ms download/
iebuild/ime5_win32/en/ime5_win32htm.
• Distance from lead edge a minimum of a .035-inch.
• Can print to within ½-inch of the trial edge.
Electronic color
dropout
The i1800 Series Scanners provide the ability to create dropout images
without changing lamps. Red, green, blue dropout functionality can be
selected. Only one color can be dropped out at a time. This dropout
performance is equivalent to color dropout functionality when using the
traditional color lamp technique.
Electronic color dropout is used with OCR and ICR applications. See
your vendor’s documentation for recommendations on image quality
characteristics.
