Open the cover and set the original face down on the scanner’ s document glass with the top edge at the front of the scanner .
17 S T E P 1 Pr eviewing The preview scan is a trial scan performed befor e the final scan that encompasses the entire scanable ar ea of the document glass. The preview image is shown in the preview window . Use this image to specify a scan area and adjust the scan settings for the image.
18 S T E P 1 Selecting the Output Device Use the following procedur es to select the output device (printer , etc.) for the scanned image. Select the device that corr esponds best to your output device and use of the image.
19 S T E P 1 Setting the Resolution and Magnification The magnification of an image can be changed before scanning to accommodate repr oductions that are larger or smaller than the original.
20 S T E P 1 T o Set the Magnification Factor Set the desired magnification factor on the control panel. Hint The Relationship Between Data V olume and Scanning Resolution The higher the magnification and scanning resolution settings, the greater the file size of scanned images.
21 S T E P 1 Setting the Scan Mode When an image is scanned, it is r ead as a collection of “dots.” The scan mode that is selected determines how each of these dots is r epresented in the output. The following four scan modes are available. Black and White Expresses images in two colors only: black or white.
22 S T E P 1 Operating Procedur es Click the arrow beside Scan Mode. Select a scan mode from the pop-up menu. Selecting the box opens the pop-up menu..
23 S T E P 1 V erifying the Image befor e Scanning Before initiating the final scan, it is advisable to check the intended r esults with the Browser function. The image in the br owser window is more accurate than the one in the preview window , allowing you to verify the results more pr ecisely before scanning.

41 S T E P 3 T o Edit the T one Curve In the T one Adjustment dialog box, click the tone curve tab. Change the tone curve in any direction to adjust its shape. Click the OK button. The image in the preview window changes to r eflect the new settings. Y ou can adjust the setting for each channel: R (red), G (gr een), B (blue) or M (master).
42 S T E P 3 The Relationship Between the T one Curve and Image Brightness T one curve values fall with a range of 0.01 to 10.00. A value of 1 appears as a straight line in the graph, and if the value is any value other than one, the line on the graph will appear curved.
43 S T E P 3 Brightness and Contrast Settings Y ou can adjust the image with two slide bars, one for contrast and one for brightness. Use this method to adjust an image before scanning if it is slightly out of focus or too dark. Hint • Y ou cannot use this feature with the black and white or color scan modes when ColorSync is selected.
44 S T E P 3 T o Adjust the Brightness and Contrast In the T one Adjustment dialog click the brightness/contrast tab. Adjust the brightness/contrast settings by dragging the slidebars, changing the value with the spinbox buttons, or entering the value directly into the entry box.
45 S T E P 3 Adjusting the Color Balance Y ou can enhance color matching by adjusting the color balance of one or all of the three primary colors: r ed, green and blue (RGB). Use this featur e to adjust the color balance when you see an over -abundance of a color in a scanned image.
46 S T E P 3 Gamma V alue Settings By adjusting the gamma value, you can more closely match brightness of the displayed image to the printed image. Adjust this value if what you see on the screen is very dif ferent from your printout.
47 S T E P 3 T o Change the Gamma V alue Settings Click the gamma tab in the T one Adjustment dialog. Click a pre-set value or the custom option. Click the [OK] button. The changes are r eflected in the image currently displayed in the pr eview window .
48 S T E P 3 Adjusting the Thr eshold V alue When the scan mode is set to black and white, the image brightness can be adjusted. The threshold value setting determines whether a halftone will be expressed as a black or a white data point. The possible thr eshold values range between 0 and 255.
49 S T E P 3 Auto T one Corr ection When the selected scan mode is Color (D ocuments) or Color (Photo s), you have three options for adjusting the color: Standard, ColorSync or None. The default setting is [Standard]. Standard Use this option if scanned images are to be viewed primarily on the computer display with photo album software.
50 S T E P 3 Unsharp Mask The Unsharp Mask function enhances the outlines of an image. When set to On, this function makes the image outlines appear sharper without changing the brightness, contrast or color balance, giving it a natural look. It is particularly useful for scanning images that are slightly out of focus.
51 S T E P 3 Descr een Moiré patterns occasionally appear when items printed at high resolutions ar e scanned. T o reduce this phenomenon, scan photographs and other high-resolution prints with the Descreen function enabled. Shut it of f to scan lower resolution items, such as newspapers, books and magazine text.
52 S T E P 3 Saving/Recalling Settings The scan mode, resolution and pr eference settings can be saved with a pr eview image to a settings file and recalled for futur e processing. The user may fr eely assign a name to the settings file. It is convenient to save frequently used settings in a file.
53 S T E P 3 T o Recall a Settings File Open the [Setting File] menu and select [Load]. Select the folder where the file is stored and click the name of the file you want to load. Click the [Open] button. The file you selected opens and the settings stored in the file ar e enabled for the T one Adjustment settings.

59 Glossary Auto T one Corr ection A function that uses brightness/contrast and gamma value settings to automatically analyze and adjust images. Bits/Bit Numbers Each dot of a 1-bit image is assigned either black or white accor ding to the threshold brightness value, r esulting in the image being repr oduced in just those two colors.
60 Color Channel Any one of the red, gr een or blue elements of a color image. Since color images are assigned 8 bits per pixel for each of the r ed, green and blue channels, each pixel is assigned 24 bits of data. The master channel is the composite of these three channels.
61 Gamma V alue A function for adjusting the overall brightness of an image. A gamma value is the mathematical expression of how brightness data is conver ted from a scanner (the input) to a monitor or printer (the output). With 1 as the base value, a gamma value less than 1 makes an image darker , while a higher value makes it brighter .
62 Moiré The patterns or lines created by overlapping dots in an image. This phenomenon is found when photographs or pictures ar e scanned from books and magazines at low resolutions. The Descr een function helps to eliminate moiré patterns. Optical Resolution An expression of the volume of data per inch (dpi) that can be sampled by a scanner .
63 Scan Mode Any one of the various methods used to repr oduce image data. Scan modes are distinguished by the number of bits used to describe each pixel. Plug-in Module CS-U features the following scan modes. • Color (Photos)/Color (Documents): assigns 8 bits of data for each color channel (RGB) in each pixel.
