Scan After all the scan settings are satisfactory, click the Scan button to start scanning your document. Close Click the Close button to leave the Scanner Properties dialog box.
User’s Manual The following table shows the default settings： Tab name Image Default settings Image：Front B&W Binarization：Dynamic Threshold Resolution：200 dpi Invert：Blank on White Scan Source：Auto Document Feeder Threshold：None Brightness：None Contrast：None Compression None Color Dropout None Paper Cropping：Automatic Deskew：Yes Orientation：Portrait OverScan：0.
4.2 The Image Tab The Image tab allows you to choose the front side and (or) the rear side of your document, the type of image, and to set several basic scan settings. Note that except for the resolution, you can set individual scan settings for the front side and the rear side. For example, all settings in the Image tab, Compression tab, Color Dropout tab can be set individually for the front and the rear side.
User’s Manual 4.2.1 The Image Selection Box The Image Selection box includes the image type and document side option. If you wish to scan both the front side and the rear side of your color document, you can check both Front Color and Rear Color at the same time. Note the options vary based on type of scanner.
Example 2：Scanning a two-sided color document, one in B&W(Drop Blue Color：Threshold：10, Background： 79), the other in color Side/Image Selection Image Type Color Gray B&W B&W Front Rear Description Choose Color if you wish to scan a color image for your original in color. Choose Gray image if your original contains actual shades of gray. Choose B&W if your original contains only text pencil or ink sketch.
User’s Manual Front/Rear Auto Color Detection: Click to automatically detect and scan the front or the rear page of your color document in color image mode. If your document is in colors, the scanner will automatically scan the document into a color image. If your document is non-color, you can choose the output to be either B&W or Gray from the Non-Color Selection option. This option is useful when you have a mixture of color and non-color document.
4.2.2 Other Image Options Binarization This is the process of converting a grayscale or color image to a bi-tonal image. There are several different methods of performing this conversion. Options: Dynamic Threshold, Fixed Processing, Halftone 1~5, Error Diffusion. Dynamic Threshold: Selecting Dynamic Threshold allows the scanner to dynamically evaluate each document to determine the optimal threshold value to produce the highest quality image.
User’s Manual Fixed Processing: Used for black-andwhite and other high contrast documents. A single level is set to determine the blackand-white transition. The threshold is programmable over the entire density range. Fixed Processing sets Contrast to 0. If Fixed Processing is selected, Contrast is not available. Halftone: In addition to the black and white display, Halftone can present a somehow gray shade of image by using different size of dots.
Error Diffusion Image 4-10
User’s Manual Threshold Used to convert a grayscale image to a bi-tonal image. The value ranges from 0 to 255. A low threshold value produces a lighter image, and can be used to subdue backgrounds and subtle, unneeded information. A high threshold value produces a darker image, and can be used to help pick up faint images. Adjust the threshold setting by dragging the Threshold sliding bar to the left or right to achieve the desired threshold setting.
Gray Document Type: Choice: Normal, Photo, Document Three options of document type are provided when you choose Gray as the image type for your scanned document. Choice: Normal, Photo, Document. • • • Document: Choose Document if your original contains pure text or a mixture of text and graphic since it is an optimal setting for regular business document. When using Document, only Threshold can be adjusted.
User’s Manual Normal Photo Document (Threshold: 230) Normal Photo Document (Threshold: 230) 4-13
Brightness Adjusts the lightness or darkness of an image. The higher the value, the brighter the image. Drag the slider to the right or left to increase or decrease the brightness. Contrast Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different grayscale. Drag the slider to the right or left to increase or decrease the contrast. The range is from –100 to +100. The range is from –100 to +100.
User’s Manual Resolution A good control of the resolution results a good detail of an image that scans. The resolution is measured by dots per inch (dpi). Normally, the greater the dpi number, the higher the resolution and the image file size. Be aware that greater resolution takes more time to scan, and more disk space for the scanning image. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space.
Resolution: 75 dpi Invert Resolution: 150 dpi Reverses the brightness and the colors in the image. The default setting is Black on a White background. Reverse mode is White on a Black background. For color images, each pixel will be changed into its complementary color at the command of Invert.
User’s Manual Scan Source Choice: y Auto Document Feeder: Used to scan multiple pages. y Flatbed: Used to scan a single page. For example, pages from newspaper clipping, paper with wrinkles or curls. y Flatbed (book): Used to scan several inside pages from book. y Automatic: Allow the scanner automatically set its scan source. If Automatic is selected and there is document in both the auto document feeder (ADF) and the flatbed, then the scan source will be automatically set to ADF.
Color Matching The purpose of Color Matching is getting the accurate color. This option uses the default parameters (ICC profile) to adjust the colors of the image. Normal After Color Matching 4.2.3 Scanning color images The following options are available for scanning color images.
