    You should consider the following when selecting a location for your scanner: Place the scanner on a flat, horizontal, stable surface. If the scanner is tilted or at an angle, it cannot operate properly. Place the scanner close enough to the computer for the cable to reach.

  • Page 16: Releasing The Transportation Screw

    Before connecting the scanner to a power source, you must release the transportation screw. 1. Place the scanner on a flat, stable surface so that its rear panel is facing you. 2. Locate the round screw knob in the middle of the rear panel.

  • Page 17: Plugging In The Scanner

    1. Firmly connect the power cable to the power inlet on the rear of the scanner and the other end into an appropriately grounded outlet as shown below. 2. If any of the scanner’s lamps come on, press the OPERATE button to turn the scanner off. Warning: Whenever you turn of the scanner, wait at least 10 seconds before turning it back on.

If this happens on both your screen and printout, the scanner’s sensor may be malfunctioning. Consult your dealer. When halftoning is used, textured patterns composed of a series of dots appear on particular areas of an image.

    How the scanner works Scanner settings ..........

  • Page 73: Scanner Functions

    These are detected as varied intensities of reflection In monochrome reading, the scanner converts the intensities into the tonal data for each pixel. In color reading, the scanner separates the various colors into three primary colors-green, red, and blue-and converts the tones of these colors for each pixel.

  • Page 74: Scanner Settings

    The data produced by the scanner needs to be reproduced to be seen as an image. This is done, for example, by displaying the image data on a computer screen or printing it on a printer. The same image data can appear different depending on how it is reproduced.
  • Page 75 180 dpi and 200% has the same number of dots as an image scanned at 360 dpi and 100%. To enlarge or reduce the image size, use the scanner’s size function through your software at the time of scanning. Avoid increasing the image size after scanning because the image quality deteriorates.
  • Page 76 64 colors (4 x 4 x 4). Eight bits/pixel/color (total 24 bits for a pixel) can represent over 16 million colors. The scanner can read up to 10 bits/pixel/color. Above 8 bits/pixel/color the scanner converts the image data to 8 bits/pixel/color and sends it to the computer.
  • Page 77 8 bits To reproduce an image of more than 2 bits/pixel/color the output device should be capable of producing the same tones. Many displays and printers cannot do this and are limited to monochrome without gradations, or to 8 or 16 or 256 colors. The data format chosen also affects the amount of data necessary for scanning and storing an image.
  • Page 78 It is better to use darker settings for line art, or faint original images, and to use lighter settings for darker original images. The brightness can be combined with any other function. The graph below shows the differences between the brightness settings when the gamma correction is set for the CRT Display A setting.

  • Page 79: Color Mode

    Dropout colors (monochrome reading only) The dropout color is the color you tell the scanner not to read. You can choose a dropout color from green, red or blue. Use a dropout color when you do not want to read one of these colors-for example, when scanning an image on a colored background.
  • Page 80 Halftoning is a process of changing an image to a pattern of dots. This is required because a printing press produces images in a different way than photography does. Photographs have an almost infinite number of tones, with an almost infinite number of colors for color photographs, but printing uses only individual single-color dots.
  • Page 81 Halftoning modes B and C are not available with color line sequence reading. Your scanner also provides four typical dither patterns for l- or 2-bits/pixel/color data format. With suitable software, you can define two more dither patterns.
  • Page 82 Haljbning mode B Halftoning mode A Halfoning mode C Dither pattern A Halftone is expressed in 4 by 4 bayer dither pattern. Dither pattern B Halftone is expressed in 4 by 4 spiral pattern.

  • Page 84 Data Darker - Lighter Gamma correction provides five settings, and can be combined with all other scanner functions. Choose an appropriate setting from the five modes below. P CRT Display A The output data is in proportion to the original image, as shown in the above graph.
  • Page 85 CRT Display B This setting is suited for analog-input CRT displays which can display an image with multiple levels of tones of more than 1 bit/pixel/color (y = 1.8). This is usually the best setting. Printer Output A This setting is suitable for highdensity printers, such as 24-dot printers and some page printers.
  • Page 86 P CRT displays This setting compensates colors for the characteristics of color CRT displays. CI Impact dot-matrix printers This setting compensates colors for the characteristics of impact dot-matrix color printers. Q Thermal transfer printers This setting compensates colors for the characteristics of thermal transfer color printers.

  • Page 88: Color Correction

    A process to convert full-color images into a limited number of primary colors. The additive primary colors (red, green, and blue) are used by the scanner and the subtractive primary colors (cyan, magenta, and yellow) plus black are used for printing press separations.
