Page 31: Prescan
Image Scanner User's Manual ¡ Prescan Function: Scanning the whole available area at a low resolution (60, 75, or 100DPI*). Usage: Use "Prescan" when you want to obtain a quick, low-resolution scanned image. You can then adjust the scan area so that subsequent scans apply to exactly the part of the original you want to scan. -
Page 32: Scanning Composition
Image Scanner User's Manual ¡ Scanning composition Function: You can scan using one of three compositions; binary, halftone, or multi-value. Binary scanning records only black and white from the original. Halftone scan- ning records gray shades on the original using a pattern of black and white dots to represent these shades. -
Page 33: Binary Scanning / Threshold
Image Scanner User's Manual ¡ Binary scanning / Threshold Function: A binary composition scanning converts every pixel on the image to either black or white. If the image contains a gray area, the threshold value determines whether the scanner records it as black or white. If the threshold value is high, the scanner records more pixels as black. -
Page 34: Halftone Scanning
Image Scanner User's Manual ¡ Halftone scanning Function: Halftone creates the illusion of gray scales by simulating shades of gray from pat- terns of black and white dots. Usage: Use halftone scanning when scaning an image with gray shadings such as a photo- graph, to be printed or displayed on a monochrome device, such as a laser printer. -
Page 35: Multi-Value Scanning
Image Scanner User's Manual ¡ Multi-value scanning Function: Multi-value scanning can record 4, 6, or 8 bits of information for each dot on the image. The 4-bit multi-value data represents 16 different shades of gray, the 6-bit data rep- resents 64 shades of gray, 8-bit data represents 256 different shades of gray. Note that the multi-value scanning uses more memory and disk space. -
Page 36: Area Extraction
Image Scanner User's Manual ¡ Area extraction Function: To extract a rectangular area from the whole scannable area. Usage: For example, if you want to extract a photograph from a page, define a rectangle over the photograph, as shown below.

Page 37: Section Area (Multi Area Settings)
Image Scanner User's Manual Section area (Multi area settings) ¡ Function: Within the scannable area, you can set rectangular areas and define scanning modes such as binary scanning, halftone scanning, or binary filter etc. for each area. Six areas can be set for one scan. These areas can be piled on top of one another and the last defined area is valid. -
Page 38: Auto Photo/Letter
Image Scanner User's Manual ¡ Auto photo/letter Function: This mode detects photo (halftone) areas and letter (binary) areas of the original so that the binary areas are scanned in the binary mode, and the halftone areas are scanned in the halftone mode. Note: This function is available only when the optional image processing unit is installed in the scanner. -
Page 39: Resolution
Image Scanner User's Manual ¡ Resolution Function: To set vertical and horizontal resolution independently at 60, 75, and 100 to 800 dots per inch. The higher the resolution, the finer the detail. However, a high resolution image requires much more memory space and processing time than a low resolution im- age. -
Page 40: Brightness
Image Scanner User's Manual ¡ Brightness Function: To adjust the brightness value between 1 and 255. A high brightness setting results in a lighter overall image. A low brightness setting results in a darker overall image. Usage: When scanning a dark image, the darker area may appear as deep black although it has gray shades. -
Page 41: Gamma Correction
Image Scanner User's Manual ¡ Gamma correction Function: To select following gamma correction settings: Normal: Emphasizes contrast slightly to improve a scanned image.

User defined: Your own gamma correction curve is loaded into the scanner. -
Page 42: Binary Filter
Image Scanner User's Manual ¡ Binary filter Function: You can use 4 binary filters; noise elimination, smoothing, thickening black lines and edge extraction in binary scanning. Noise elimination: Eliminates independent black or white dots. Smoothing: Flattens uneven dots. Thickening black lines: Thickens thin lines. Edge extraction: Extracts outlines of the image. -
