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.
Page 3
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.
Page 4
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. •...

Jam and fault This section provides recommendations for application logic associated with scanner jam and fault recovery. 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.
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.
Starting image address/ The host application must always seed the scanner with the starting next image address 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.
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:...
Page 16
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: •...
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. •...

For example, if you scan a book with two sections (Section 1 contains 2 chapters, each having 40 pages;...
Controlling document The previous Indexing Scheme examples illustrated how document level changes 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: •...
• Distance from lead edge a minimum of a .035-inch. • Can print to within ½-inch of the trial edge. Electronic color The i1800 Series Scanners provide the ability to create dropout images without changing lamps. Red, green, blue dropout functionality can be dropout selected.
Page 21
Two categories of performance are provided or each color: Colors that can be completely dropped out and colors that are very close to complete dropout. These values were established by using standard Pantone Matching System® Colors guide (uncoated, 175-line screen). If the background of the document you are using is not bright white the results may vary.
Page 23
Image header An image header is associated with every image captured by the scanner. Following is a list of information available in the image header. information Image length size of the image. Image identifier indicates whether the image is front black and white, back black and white, front color or back color.
Page 24
Image address level (Document level) the document level is assigned by the operator by using: • the level key, • a patch if the Patch Reader is enabled, • the host application to set the next image address, or •...
Page 25
Zone processing Some applications have a requirement to store part of an image in color or grayscale and the rest of the image in black and white format (this saves storage space by not storing the entire image in color or grayscale).
Programmable keys Programmable keys are available for use by the operator when the scanner is enabled. The touchscreen displays the functions that are associated with these programmable keys. The programmable keys can be assigned the following functions: • No scanner functionality (default) •...
Page 27
Transfer Patch Code The image header reflects when a Transfer patch code is detected on a document. A document containing a Transfer patch is considered to be a Level 0 document. The IA level for the next document following the Transfer patch is assigned to the level (Level 2 or Level 3) that has been previously set.
Page 28
Batching Batching information only applies when the scanner is configured with Image Address enabled via the operator control panel touchscreen. Batching provides a way for the scanner to perform a specific function after scanning a designated number of documents at a particular IA level.
