2 Scanning Concepts
This chapter provides an overview of the scanning process, a
discussion of error conditions, and two methods of fault recovery.
Scanning documents Follow this sequence to scan documents: set up the scanner,
enable scanning, initiate polling, feed documents, and disable
scanning.
Setup To set up the scanner:
1. Determine and select the mode (configuration) to be used for
the current application.
The mode may be selected by the host computer using a
scanner-unique command (HA), or by the operator using the
scanner control panel.
2. Determine if any changes to the Image Processing parameters
need to be made for the current application. Execute the
required scanner-unique command(s) to make the desired
changes.
Image Processing parameter changes remain in effect until
one of the following conditions occur:
— The scanner is powered down using the main power
switch.
— A SCSI bus device Reset command is executed.
— A single parameter change is overridden by another
change to the same parameter.
3. Set the Sequential ID Number Seed and/or the Next Image
Address using a scanner-unique command (DC and HC,
respectively), if desired.
4. Calibrate the scanner. For procedures on how to do this, see
the
Kodak Digital Science Scanner 9500, User’s Guide.
5. Prepare documents according to the instructions found in the
Kodak Digital Science Scanner 9500, User’s Guide .

2-2 A-61124 March 1999
Enable scanning The host must issue a SCSI Scan command (XX) 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.
Feed documents Feed documents according to the instructions found in the
Kodak
Digital Science
Document Scanner 9500, 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 disabled when one of the following conditions occur:
• The scanner is first powered on using the main power switch.
• A SCSI bus device Reset command is executed.
• An End-of-Job indicator is sent by the operator from the
scanner control panel.
• A scanner-unique End-of-Job command (GX) is issued by the
host computer.
• An error occurs requiring fault recovery.
• The scanner portion of the machine has not been calibrated.
NOTE:Once scanning has been disabled, documents cannot be
scanned until the host enables scanning by issuing a
SCSI Scan command.
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 scanner control panel, while others are reported
to both the host and the scanner control panel.
An error (via the SCSI interface) is defined as either a current
error or a 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.

A-61124 March 1999 2-3
When an error occurs, the host will receive a SCSI 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 SCSI
Request Sense command. The Sense data will indicate the type
of error that has occurred.
To receive subsequent pending errors, the host must execute a
SCSI 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 SCSI 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 scanner
control panel. This is done to prevent additional images from
entering the image buffer while allowing the host to perform fault
recovery activities. To aid in fault recovery, the information bytes
of the Request Sense data will contain a Sequential ID Number
for the approximate image upon which the error occurred.
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.

2-4 A-61124 March 1999
Fault recovery Fault recovery methods are required when unanticipated
circumstances interrupt scanning, such as a document jam. The
two methods described below meet the needs of most users.
However, other methods may be used.
IMPORTANT:
Before beginning fault recovery, make sure all the
images and headers have been transferred from
the image buffer to the host system.
Interactive/online method Use the Interactive/online method when your primary concern is
that the database has no duplicate images.
Follow these steps to use the Interactive/online method:
1. At the host system, search through the most recently scanned
files to determine which images have been scanned and
transferred.
2. Find the last successfully scanned image. Record the
Sequential ID Number and/or the image address assigned to
the last successfully scanned image.
3. Sort through the stack of documents being scanned to find the
document that produced the last successfully scanned image.
You will have to rescan all of the documents that follow the last
successfully scanned document.
4. Download the Sequential ID Number and/or the Next Image
Address using a scanner-unique command (DC and HC,
respectively). The value(s) you download should correspond
to the document following the last successfully scanned image.
5. Begin scanning the documents that follow the last successfully
scanned document.
Batch/offline method Use the Batch/offline method when your primary concern is
efficient use of time, duplicates in the database do not present a
problem, and there is adequate space in the database for the
duplicate images (same images with different Sequential ID
Numbers and image addresses).
Follow these steps to use the Batch/offline method:
1. Remove the stack of successfully scanned documents from
the exit hopper.
2. Take the last three or four documents from the top of the stack
and put them into the feed tray or at the top of the next stack
of documents.
3. Begin scanning the documents.

3 Image Headers
Image header contents This chapter provides an overview of the type of information
generated during the scanning process, and how to retrieve
images and headers.
The scanner collects the following information for each document
scanned:
Document number (Sequential ID Number)
The scanner assigns a unique Sequential ID Number to each
document. This number may be initialized by the host computer
using a scanner-unique command.
Image size
The scanner records the number of bytes required to store the
scanned document image.
Document level
The scanner assigns a document level to the scanned document
in one of the following ways:
•Press one of the Level Keys (I, II, III) on the control panel.
•Execute function code F94 (Level 1), F95 (Level 2), F96
(Level 3), or F07 (Level 0).
•Use the Footswitch accessory, if it is installed and enabled.
•Use a patch, if the Patch Reader accessory is installed and
enabled.
NOTE:If you do not use one of the methods above to assign a
document level, the level will be determined by the
mode defaults.
For example, assume the mode defaults assign a Level
2 to a document that follows a Level 3 document; and a
Level 1 to a document that follows a Level 2 document.
If the last document was assigned a Level 3, then the
current document is assigned a Level 2.
Mode
The scanner records the current operating mode that was
selected for the application.
Line length
The scanner records the number of pixels-per-line in an image.
Page length
The scanner records the number of lines-per-page in an image.

3-2 A-61124 March 1999
Image address
The scanner assigns an image address to the scanned
document. The image address is based upon the index format
defined in the current operating mode and the document level
assigned to the document. Refer to Appendix C,
Assigning
Image Addresses
for additional information.
Header flags
The scanner records any flags that have been set for special
consideration. For example, a document image that may need to
go through a quality assurance check can be denoted by setting
a flag via the scanner control panel.
There are two types of flags:
•Latched flags. A latched flag is enabled and remains set until it
is disabled. In this case, the operator can execute function
code F73 and feed a set of documents. A flag is placed in the
header of all documents scanned until the operator executes
function code F73 to disable or reset the flag.
•Momentary flag. A momentary flag is set only for the next
document to be scanned. The operator can execute function
code F74 to momentarily set the flag and feed the document.
The flag is automatically reset for the next document.
Compression type
The scanner records the compression type used, which is
determined by either the mode definition or by the mode
definition override.
Date
The scanner records the date the document is scanned.
Time
The scanner records the time the document is scanned .
Resolution
The scanner records the selected scanned image resolution.
Bit order
The scanner records the selected bit order.
Skew Detection
If the Advanced Document Controller accessory is installed and
enabled, the scanner records whether or not a skew error was
detected.
Polarity
The scanner records the image polarity.

A-61124 March 1999 3-3
Bar code header information
If the Bar Code Accessory is installed and enabled and a bar
code is detected on the document, the decoded information is
included in the image header.
Bar code information can contain a maximum of 106 ASCII
characters:
•80 characters of actual data
•9 delimiters
•a colon
•14 bytes of image address information
•a line feed
•a null terminator
Samples:
<Bar Code>:<IA><line feed><null>
<Bar Code 1>;<Bar Code 2>;<Bar Code 3>:<IA><line
feed><null>
When using bar code, some situations may require evaluation of
Image Header data and, perhaps, manual cleanup of the
information contained in the header:
• During normal bar code reading, if a bar code is not decoded
properly (i.e., not recognized or only a portion of the code is
recognized), the bar code data will not appear in the image
header. For example, if there are two bar codes on a
document and only the second bar code is read and decoded
properly, only the data contained in the second bar code will
appear in the image header (making it appear as though only
one bar code was placed on the document).
• During partial bar code reading, if a bar code is not decoded
(i.e., not recognized or only a portion of the code is
recognized), a question mark may appear in the image
header. For example, if the start character followed by the
minimum number of characters is readable, the image header
will contain bar code information (corresponding to what has
been successfully read and decoded) followed by a semi-
colon (;) and a question mark (?).
• During reading of multiple bar codes, duplicate bar code
information may be placed in the header.
Image Deskew Flag
If the image was successfully skew corrected, this flag is set to 1
otherwise this flag is set to 0. This requires the Image Manager.
Skew Angle
The scanner will report the detected skew angle from 0 to 44
degrees independent of whether the image was skew corrected.
This requires the Image Manager.
