Modes

Linked modes

The following information will provide you with the basic concepts associated with scanning documents.

The Scanner offers eighteen (18) modes which may be defined for a particular application or group of applications.

When you select a mode for use with a particular application, you are selecting the format/appearance of the output. Each mode consists of definitions which affect the output of the Scanner. Required mode definitions include index format, level to follow level rules, etc. Optional mode definitions include a variety of accessory options, such as turning the endorser on or off. The mode definitions are established during installation.

Many of the optional mode definitions established during installation may be overridden using function codes. The overrides are temporary, unless during installation it is specified that the mode overrides be saved. Upon execution of a function which overrides a prior definition, a plus sign (+) will appear in the first line of the status display if the mode overrides are saved.

Mode override indicator

Please Wait...

Linking modes eliminates the requirement of re-entering the Image Address when changing from one mode to another. When two modes are linked, you may change from one mode to another, maintaining the Image Address.

Modes are linked by defining the same Index Format and Image Address Fields (both number of fields and individual field lengths) during installation.

NOTE: The Level Rule options defined during installation do not have to be the same to link modes.

To change from one mode to another, maintaining the Image Address, use Function Code F91.

Image addresses

Assigning an image address

An Image Address is assigned to every document scanned. An Image Address consists of four fields, each of which represent a different document level. An Image Address has a maximum length of fifteen (15) characters; twelve (12) alphanumerics (Field A, Field B, and Field C must be numeric; the Fixed Field may contain alphanumerics) and three

(3) delimiters (inserted between fields).

The Image Address (number of fields and characters) is based upon the indexing scheme chosen (refer to Indexing Schemes ).

Regardless of the indexing scheme used, the following four fields must be defined during installation for each mode:

???Field A. A numeric field representing document Level 1.

Its value is incremented whenever a document is assigned Level 1.

???Field B. A numeric field representing document Level 2.

Its value is incremented whenever a document is assigned Level 2.

???Field C. A numeric field representing document Level 3.

Its value is incremented whenever a document is assigned Level 3.

???Fixed Field. An alphanumeric field containing fixed information; typically, the date.

An example of an Image Address is:

1201.01.020.005

where:

???Field A (Level 1) contains 005.

???Field B (Level 2) contains 020.

???Field C (Level 3) contains 01.

???Fixed Field contains 1201.

An Image Address may be assigned or changed by pressing the NEXT key or by entering Function Code F92. The NEXT key (or Function Code F97) is used when setting/changing any or all of the Image Address fields.

Function Code F92 is used when setting/changing only the Fixed Field of the Image Address.

Image address formats

Indexing schemes

The Image Address may be displayed in the status display, and printed on the original document(s) as they are transported through the system.

The format in which the Image Address appears when displayed, written, or printed is defined during installation for each mode.

The written/printed Image Address may appear in one of three formats:

???Display leading zeros format 004.003.002.001

???Suppress leading zeros format 004. 3. 2. 1

???Compress leading zeros format 004.3.2.1

NOTE: The format chosen does not affect the Fixed Field of the Image Address; it is always displayed and printed in its entirety.

The purpose of scanning documents is to record the information contained on the documents in an easily accessible form.

In order to access or retrieve the information recorded, an indexing scheme is used to assist you in locating the desired information.

The indexing scheme is defined during installation for each mode.

The Scanner offers five indexing schemes:

???Single Level.

???Two Level.

???Two Level Offset.

???Three Level.

???Three Level Offset.

Example of two level offset indexing

Let's use the scanning of a book as an example. Assume that the book contains two chapters; Chapter 1 has forty (40) pages and Chapter 2 has sixty (60) pages.

The Image Address has been defined:

???Field A has zero (0) characters.

???Field B has two (2) characters.

???Field C has zero (0) characters.

???Fixed Field has zero (0) characters.

Three level indexing

Example of three level indexing

When using this scheme, the Image Address (IA) assigned to each document is defined as follows:

???Field A (Level 1) is defined as having a field length greater than zero.

???Field B (Level 2) is defined as having a field length greater than zero.

???Field C (Level 3) is defined as having a field length greater than zero.

???Fixed Field may be defined, if desired.

Let's use the scanning of a book as an example. Assume that the book contains two sections; Section One contains two chapters, each having forty (40) pages; Section Two contains only one chapter, having one-hundred twenty (120) pages.

The Image Address has been defined:

???Field A has three (3) characters.

???Field B has two (2) characters.

???Field C has one (1) character.

???Fixed Field has zero (0) characters.

Three level offset indexing

Example of three level offset indexing

When using this scheme, the Image Address (IA) assigned to each document is defined as follows:

???Field A (Level 1) is defined as having a field length of zero.

???Field B (Level 2) is defined as having a field length greater than zero.

???Field C (Level 3) is defined as having a field length greater than zero.

???Fixed Field may be defined, if desired.

Let's use the scanning of a book as an example. Assume that the book contains two distinct sections; Section One contains two chapters, each having forty (40) pages; Section Two contains only one chapter, having one-hundred twenty (120) pages.

The Image Address has been defined:

???Field A has zero (0) characters.

???Field B has two (2) characters.

???Field C has one (1) character.

???Fixed Field has zero (0) characters.

Controlling document level changes

Throughout the Indexing Schemes examples, you have seen document levels change within a single group of documents. There are four document image levels: 3, 2, 1, and 0.

There are a number of ways in which user can set or change the document level:

???You may press a document Level Key on the Control Panel to assign a document Level 3, 2, or 1.

???You may use Function Code F07 to assign a document Level 0.

???You may use the optional KODAK IMAGELINK??? Footswitch accessory; pressing, pressing and holding, or releasing the Footswitch can change document levels.

???You may use the optional KODAK IMAGELINK??? Patch Reader accessory; feeding a document containing a particular type of patch can change document levels.

If the user does 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 installation for each mode.

The following diagram illustrates how document levels are set or changed:

Special considerations

Checking the meters

The topics presented in this section apply to the general usage of the Scanner.

Checking the meters is useful in determining:

???maintenance schedules.

???the length of time required to complete a job.

To view the run time display, enter Function Code F17. The display will show three (3) meters: Meter A shows the number of motor-on hours; Meter B shows the number of transport-on hours; and Meter C shows the number of AC-on hours. Press the right arrow key to view each meter in turn. In addition, the non-resettable document count is shown as Meter D.

Press the Clear key to clear the display.

Scanning considerations

Image headers

Header flags

The topics presented in this section apply to document scanning.

Image Headers are created when documents are scanned. Each scanned document has its own individual image header, containing information such as:

???Document number (sequential number)

???Image size

???Document Level

???Mode

???Line length

???Page length

???Image Address

???Compression type

???Date

???Time

???Resolution

???Bit Order

???Skew

???Header flags

???Optional information (i.e., bar code information)

The document image header is sent ahead of the scanned document image to the host computer. The image header and document image are then stored on a magnetic or optical disk media. The information contained in the header is later used to retrieve the document images (most often using the Image Address or bar code information stored in the header).

Header flags are used to alert the host system that the document(s) fed into the transport are of special interest. There are two types of flags: latched and momentary.

The latched flag is activated by performing Function Code F73.

When the latched flag is set, the Image Header for the current document (or the next document fed into the transport) and all documents which follow will contain a header flag. The latched flag will remain activated until it is turned off by again performing Function Code F73.

NOTE: A flag symbol will appear in the first line of the status display until the latched flag is turned off.

The momentary flag is activated by performing Function Code F74. When the momentary flag is set, the Image Header for the current document (or the next document fed into the transport) only will contain a header flag.

Turning on the Scanner

The following steps are necessary to prepare the Scanner for operation:

???Turn on the Main Power Switch (located at the rear of the machine).

???Turn on the Side Panel Switch.

???Select the language display.

???Calibrate the Scanner.

???Adjust the Feed and Separator Roller gap.

???Adjust the Feed Shelf position.

???Adjust the Feed Shelf Side Guides.

???Adjust the Exit Hopper Side Guides and End Stop.

???Change the Deflector (if required).

???Prepare documents for scanning.

The following steps are required to power on the Scanner:

1.Turn on the Main Power Switch (located at the rear of the machine).

NOTE: It is not necessary to turn off the Main Power Switch during normal daily operation.

2.Turn on the Side Panel Switch.

Wait until the Status Display indicators are lit and an operating display appears before you continue.

Selecting the language display

The Scanner may have been configured at installation to allow use of a second language in the status display. The language used (French, German, Italian, Spanish, or other) is defined during installation. If available, the alternate language display may be accessed using Function Code F19.

Calibrating the Scanner

Calibration sets the intensity of the lamps, which contribute to the overall quality of the scanned document image.

The Scanner should be calibrated:

???At least once a day when the Scanner is turned on using the Side Panel Switch - prior to scanning documents.

???Any time the Scanner is turned on using the Main Power Switch.

???If image quality is poor.

???After changing lamps.

Calibrate the Scanner using a calibration target (sheet of paper) that is:

???Blank.

???Clean.

???Matte finish (not glossy).

???White or the same color as the background color of the documents to be scanned. If you are scanning a variety of colored documents, use a white calibration target.

???Wider than the documents you are going to scan (i.e. to scan 8.5 x 11 inch (215.9 x 279.4 mm) documents, the calibration target should be wider than 8.5 inches/215.9 mm). The recommended width for the calibration target is 12 inches (300 mm).

1.Verify that the Main Power Switch (located at the rear of the Scanner) and Side Panel Switch are on. A normal operating Status Display should appear.

2.Press P-Key P1 or enter Function Code F37 to initiate the calibration sequence.

3.Insert the calibration target into the feeder.

Calibration

Target

When the calibration is successful, the Status Display will return to a normal operating display.

Adjusting the feed and separator roller gap

The gap adjustment knob on the Control Panel increases or decreases the space between the feed and separator rollers. The gap must be adjusted properly for smooth transportation of documents without document overlap.

When documents of different thicknesses are fed in a group, adjust the gap using the thinnest document in the group.

The feed and separator roller gap may have to be adjusted to compensate for:

???Very thin documents (onion skin, tracing paper, etc.).

???Very thick documents (card stock, punch cards, cover stock).

???Some coated documents (photographic paper, plastic-coated paper).

If the gap is not adjusted properly:

???More than one document at a time may be drawn into the transport system at the same time; not all of the documents will be scanned.

???Documents may be drawn into the transport too quickly; documents may overlap or be spaced to closely (causing an error display).

???Documents may become skewed during transport; jamming may occur.

NOTE: Prior to performing the adjustment procedure outlined in this section, the Scanner must be calibrated and enabled.

1.Turn on the Side Panel Switch.

2.Enter Function Code F04 and enable counting-only.

3.Press Enter.

4.Press Run.

IMPORTANT: Do not make a gap adjustment while documents are in the feeder or transport system; doing so will produce an inaccurate adjustment.

Adjusting the feed shelf position

Before you begin feeding documents into the Scanner, adjust the position of the Feed Shelf:

Work Shelf

Notch

Groove

Height

Adjustment

Legs

To automatically feed multiple documents, the feed shelf should be in the raised position (as shown above). To raise the feed shelf, grasp the notch and lift the feed shelf. Swing the height adjustment legs out and insert them into the groove on the work shelf.

To hand feed documents (one at a time), the feed shelf should be in the down position (not shown). To lower the feed shelf, grasp the notch and lift the feed shelf until the height adjustment legs are no longer resting in the groove on the work shelf. Tuck the height adjustment legs in and gently lower the feed shelf into position, level with the work shelf.

Adjusting the feed shelf side guides

Before you begin processing documents, adjust the side guides on the feed shelf to accomodate the documents being processed.

2.Slide apart the Side Guides on the Feed Shelf until the Feed Shelf Label is visible.

Adjusting the exit hopper side guides and end stop

The Exit Hopper Side Guides and End Stop must be adjusted so that documents will be stacked properly after processing.

1.Adjust the Side Guides on the Exit Hopper to match the adjustment of the Side Guides on the Feed Shelf.

2.Adjust the End Stop of the Exit Hopper by determining the longest document to be processed. Slide the End Stop until the Arrows point to where the length of the longest document is shown on the Exit Hopper Label.

Changing the deflector

The Scanner comes with two deflectors (stored in the pocket located inside the right-side access door), designed to help stack the documents as they exit the transport system and enter the exit hopper.

Use the short deflector for documents less than 5 inches (13 cm) and the long deflector for documents longer than 5 inches (13 cm) as well as for mixed sizes.

1. Grasp the deflector near the attachment pin (as shown).

2.Guide the deflector into the exit hopper, just below the lip of the hopper, to insert the attachment pin in the holding clip.

3.Pull the deflector toward you until it clicks into place.

Preparing documents for scanning

Before you begin processing documents, make certain that the documents may be fed through the Scanner easily:

???Remove any staples, rubber bands, loose mending tape, or paper clips from the documents to be processed.

???Straighten wrinkled edges and tape any torn documents.

???Trim ragged edges.

When using the automatic feeder, make certain all documents are of similar size and, texture, thickness, and weight, and that the leading edges of all documents are aligned.

Selecting a mode

Temporary operating values

The Scanner offers eighteen (18) modes which may be programmed for a particular application or group of applications.

The modes are programmed at the time of installation and stored for easy access and use.

Typically, the mode will be selected via the host system, using a scanner-unique command. However, the operator may manually select a mode.

There are two methods which may be used by the operator to select a mode:

???Use Function Code F01, Select Mode, to enter a mode number.

-Press the F key.

-Press the numeric key 0 and then 1.

-Press Enter.

-Press the numeric keys which correspond to the desired mode. (i.e., to enter mode number 15, press the numeric key 1 and then 5.)

-Press Enter.

???The mode selection function may be preprogrammed and accessible using one of the P-keys. Ask your system administrator if any one of the P-keys has been programmed to perform this function.

Each of the eighteen (18) modes which are programmed at the time of installation contain definitions which affect the output of the Scanner. Each mode is programmed to conform to the output requirements of a particular application or group of applications.

There may be instances, however, when a particular application requires some variation of an existing mode. In such instances, mode definitions may be changed using available Function Codes.

NOTE: Changes to mode definitions will remain in effect until another mode is selected or the side panel switch is turned off. The original mode definition is only affected by these changes if the mode overrides are saved (the mode override option may be selected at installation and if selected, a plus sign (+) will appear in the first line of the status display).

Example:

Assume that mode 15 contains definitions which allow use of the KODAK IMAGELINK??? Endorser. The starting print position (which defines how far from the leading edge of the document the endorsement is printed) is programmed to be 0.5 inches.

If there is a special application which requires that the endorsement be printed 1.0 inch from the leading edge of the document, you may use Function Code F59 to temporarily change the starting print position.

Feeding documents

After the Scanner has been prepared for operation and the desired mode and any temporary operating values have been defined, you are ready to feed documents into the transport.

1.Verify that the side panel switch is on. Also verify that all of the proper adjustments have been made (feeder side guides, exit hopper side guides, etc.).

2.Press the Run key.

3.Select a stack of documents which is no more than 1.5 inch thick.

4.Fan the stack of documents so that the leading edge of the top document will engage the feed/separator rollers first (refer to the illustration above).

5.Place the stack of fanned documents into the feeder so that the leading edge of the top document contacts the feed/separator rollers. The documents will be drawn into the transport, with the top document being fed first. The documents will be deposited in the exit hopper face down, in the order in which they were fed into the transport.

6.Repeat steps (3) through (5) until all of the application documents have been fed into the transport.

7.Press the Stop key after all documents have been deposited in the exit hopper.

Using function codes

There are a variety of functions available which may be used to temporarily change operating conditions and values, and to obtain system and accessory status information.

To execute a function code:

???Press the F key.

???Press the numeric keys which correspond to the desired function code.

???Press the Enter key.

9.Push down on the baffle handle to release the baffle plate. Raise the baffle plate into its original position.

10.. Close the right-side access door and top cover.

Monthly maintenance procedures

Checking the air filter

Maintenance procedures which should be performed monthly include: checking the air filter.

The air filter should be checked at least once a month and changed as needed.

1.Remove the air filter cover by pressing in on the top of the cover to release the catch.

2.Examine the filter for dust accumulation. If dust has accumulated, follow the instructions in the Replacement Procedures.

Replacement procedures

Replacing the air filter

Replacement procedures should be performed on an as needed basis. Components which need periodic replacement include: the air filter, the Document Scanning Array lamp, and the exposure lamps.

The air filter should be replaced at least once a year; more often if needed.

IMPORTANT: Never operate the Scanner without an air filter installed. The imaging apparatus will quickly become contaminated with dust and dirt, impairing image quality.

1.Remove the air filter cover by pressing in on the top of the cover to release the catch.

2.Carefully remove the old air filter. Note the orientation of the filter as it is removed from the machine.

3.Orient a new air filter the same as the old air filter, and insert it into the space left open by the old air filter.

4.Replace the air filter cover by first inserting the bottom edge and then pushing in the top edge until it is in place.

Replacing the document scanning array lamp

NOTE: The Document Scanning Array is an optional accessory which is available only when using a Scanner 923. If your Scanner does not have a DSA, proceed to the next section.

The Document Scanning Array lamp should be replaced whenever a message appears in the Status Display which indicates that the lamp needs to be replaced.

1.Turn the side panel switch off.

2.Open the front cover.

3.Locate the Document Scanning Array.

Document Scanning

Array

Replacing the exposure lamps

The exposure system consists of four (4) long-life flourescent lamps. There are two lamp housings; one upper and one lower. Each lamp housing contains two (2) lamps.

Change the lamps every five-hundred (500) hours, when image quality appears to be degrading (and standard maintenance procedures do not improve the image quality), or when requested to do so via an operator message. Always replace both lamps in a housing at the same time, or exposures may appear inconsistent. Always use the recommended lamps, or image quality may be unacceptable.

1.Turn the side panel switch off.

2.Open the right side access door.

3.Remove the imaging guides.

(Refer to Changing the imaging guides. )

4.Grasp the tab at the end of the upper lamp housing and slide the housing out of the track.
