1 Introduction Kodak i100 Series Scanners The Kodak i100 Series Scanners are low-volume production scanners which include image processing technology, can improve image quality and sometimes make the reproduction better than the original. You can use the applications based on the ISIS Driver or TWAIN Data source to enable image processing (both are available on the CD included with the scanner). Kodak Capture Software is also available as a choice for your scanning application. O

i100 Series Scanners can return bi-tonal, grayscale or color images to Image outputs the host. Below is a description of the valid combinations. The i150 Scanner is a simplex scanner. This means that only one side of the document may be captured. The i160 Scanner is a duplex scanner. This means both the front and the rear side of each document may be captured. For each side captured, the scanner can be configured to return either one or two images per side: • Single output (one image p

These image files can be controlled through the application 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

2 Best Practices This chapter provides you with recommendations for program logic, which will allow you to interact efficiently with the i100 Series Scanner. This high-level information is not intended to be used as a programming 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 • Controlling print

Scanner setup To setup the scanner: 1. Setup your scanner operating conditions: • simplex/duplex • image order • 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 • Energy Star timeout • confirmation tone For information on programming these conditions, see Chapters 3 or 4 (depending on your driver). For other vendor tool kits, refer to their

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 o

Error handling The scanner recognizes and reports a variety of error conditions. Some errors are reported to the host (via the 1394 interface) or via the LEDs on the scanner while others are reported to both the host and the LEDs. An error (via the 1394 interface) is defined as either a current or deferred error. A current error results from a problem in processing the current scanner command. This can include sending an invalid command, trying to read from an empty image buffer, or an

This section provides general recommendations regarding the impact Image file storage of image file storage locations on the overall throughput of the scanner. locations Depending upon your application, you can receive up to four image files per document. Decisions about where to write these files when retrieving them could impact the overall throughput of the scanner. In order to prevent overwriting data the scanner stops feeding paper when the internal image buffer is almost full. Sca

When using Adaptive Threshold Processing, there are four imaging parameters which effect electronic color dropout: Threshold Value/Filter Threshold, Background Value/Background, Contrast %, and Threshold. The default settings are: Contrast% = 50 Threshold = 90 Color Filter = 175 Background = 245 If the values above do not give you the desired results, you may need to vary these values accordingly. When using iThresholding, there are three imaging parameters which effect electronic
