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. Two of the options are Dynamic Threshold and Fixed Processing.

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. This is used to scan mixed document containing faint text, shaded background, or color background with a single setting. If Dynamic Threshold is selected, Threshold, Brightness, and Contrast are not available.

Fixed Processing: Used for black-and-white and other high contrast documents. A single level is set to determine the black-and-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.

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.

200 dpi,
Threshold:80,
Brightness: 0

200 dpi,
Threshold: 170,
Brightness: 0

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. The range is from -100 to +100.

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.

Brightness: -50

Brightness: 0 (Normal)

Brightness: +50

Contrast: -50

Contrast: 0 (Normal)

Contrast: +50

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. A higher resolution (usually means over 600 dpi) is only recommended when you need to scan a small area at True Color mode.

Choose a resolution value from the drop down list. The default value is 200 dpi. Available resolutions are 75, 100, 150, 200,300, 400 and 600. Or you may choose your desired value by clicking the box in the right side of the drop down list and press the arrow key to select your desired value and then click the Add button to include it in the drop down list.

Resolution: 75 dpi

Resolution: 150 dpi

Invert

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.

4.3 THE COMPRESSION TAB

The Compression tab allows you to compress your scanned image and choose the level of compression. Bi-tonal images are normally compressed using CCITT standard called Group 4 (G4). Color and grayscale images are often compressed using JPEG technology. Move the JPEG Quality slider to the right or left to increase or decrease the level of compression. Note the greater the compression level, the lower image quality. Default is 50% .

Note that the compression depends on your image editing application. If your image editing application does not support the type of compression format, then either a warning message will appear or the image quality of the compressed file will not be acceptable.

JPEG (Joint Photographic Editor Group). This group developed and lent their name to a file compression standard for color and grayscale images that is widely used by scanners, and software applications. On Microsoft Windows-based systems, a file with the extension .jpg has normally been compressed using this standard.

For scanning color or gray images, the following compressions are available:

• None
  JPEG

For scanning B&W images, the following compressions are available:

• None
  G4

The Compression tab dialog box

4.4 THE COLOR DROPOUT TAB

4.4.1 COLOR DROPOUT SELECTION

Color Dropout tab allows you to drop either of the red, blue, or green color in your scanned image. If your image contains red color watermark or background, choose the R (Red) channel then any red watermark or background will be removed. This feature is used to sharpen your text when using OCR (Optical Character Recognition) software.

Note that this function supports only black & white and gray images. Therefore, be sure to choose any black & white or gray image type while applying this function.

The Color Dropout dialog box

Advanced Processing provides two options that can adjust your scanned image in the best optimal result.

Filter Threshold

This value is used to determine the color which will be dropped out. A lower value will drop more of the selected color out, while a higher value will leave more of the selected color in.

Background Level

The pixel which is higher than the background value will be adjusted to the lightest point. Adjust the value for both the Filter Threshold and Background Level to produce the best optimal result.

Example, slightly adjusting the background value makes your text more clear.

Original

Remove Blue, Threshold: 20, Background: 255

Remove Blue, Threshold: 20, Background Level: 210

4.5 THE PAPER TAB

The Paper tab allows you to define values relating to image output (i.e., Auto Crop or not, Scan Area, OverScan, Multi-Feed Detection).

The Paper tab dialog box

4.5.1 CROPPING

• Cropping allows you to capture a portion of the document being scanned. Choice: Automatic, Fixed to Transport, EOP (End of Page) Detecting

Options	Description
Automatic	Automatic adjusts the cropping window according to different document sizes. Use this option for batches of mixed-sized documents.
Fixed to Transport	This feature allows you to define the area or zone to be imaged. Use for batches of same-sized documents. If you select this option, you can use the arrow keys to define the x and y offset values, width and length to redefine your scanned area. The Display window will show image placement as you change the values.
EOP (End of Page) Detection	This feature allows you to define the area or zone to be imaged. Use for batches of same-width but different length documents. If you select this option, you can use the arrow keys to define the x and y offset values, width and length to redefine your scanned area. The Display window will show image placement as you change the values.

The following options are only available when Fixed to Transport is selected.

• X-Offset — the distance from the left end of the scanner to the left edge of the scanning area.
• Y-Offset — the position from the top end of the document to the top end of the scanning area.
• Width — the width of the scanning area.
  Length - the length of the scanning area.

• Center: automatically calculates the x-offset for center-fed feeding based upon document size selected.

• relocate the scan area by click the arrow key on the cross sign while retain the scan size. View the result from the Display window.

OverScan

Overscan allows you to add a specific margin at top and bottom or right and left (Options vary based on the type of scanner) of the edge of the image. This is used to reduce possible corner clipping on the skewed images and often applied to a batch of skewed document to be scanned in the auto document feeder. Select a value between 0 and +5 mm . Note the overscan result will not be shown in the Display window and that the availability of the function varies based on type of scanner.

Multi-Feed Detection

Multi-Feed Detection allows you to detect overlapped document that go through the auto document feeder. Multi-Feed usually occurs due to stapled documents, adhesives on documents, or electro-statically charged document. Note : The availability of the function varies based on type of scanner.

Additional Length Detection

Additional Length Detection allows you to define the length of document being multi-fed. This value indicates the additional length exceeding your scan area. The Display window will show the size of the document as you change the value. A value of 0 indicates no additional length detection. The Additional Length Detection is best used when scanning same-size documents in the auto document feeder.

Example : Additional Length Detection : Set Additional Length to be 2.02 inches

There are two options available if Multi-Feed is detected.

- Stop Scanning after Multi-Feed

If this is selected, the scanner will stop the feeder if multi-feed is detected.

6.5 PERFORMING CONTINUOUS SCAN FROM THE FLATBED

If your scanner comes with a flatbed module, Button Manager provides you a convenient feature to perform continuous (multi-page) scan from the flatbed. Simply inserting next page of your document and then pressing the Scan button, your multi-page scan from the flatbed can be completed. This feature is particularly useful when you need to scan inside pages of a book.

To perform continuous scan from the flatbed,

1. Open the document cover.
2. Place your document with the text facing down on the glass. Make sure that the upper left corner of your document is near the home position as marked by arrow.

1. From the Button Properties window, choose your file format to be PDF, TIFF, or DjVu.
2. From the Options tab in the Button Properties window, choose "Multi-Page".

1. Check if the number displayed in the LCD screen is your favorable setting for the scanned image.
2. Press the Scan button on the scanner.
3. When the scanner completes first-page scan, a "Continue or stop" dialog box appears.

1. Place next page of your document on the glass.
2. Choose "Continue" or simply press the Scan button on the scanner to scan next page.
3. If your scan is completed, click "Stop" to close the dialog box.

Note:

1. The scanner is designed to automatically set your scan source. If your scanner is equipped with both the auto document feeder and the flatbed, the scanner can automatically set your scan source whenever there is paper on the source. However, if there is paper on both the auto document feeder and the flatbed, the scanner will set auto document feeder to be the scan source.
2. If you choose to perform flatbed scan, the scanner can still perform "automatic crop" and "deskew" for the scanned image. However, the "Multi-feed Detection" and "Duplex" functions will be disabled.

8. TROUBLESHOOTING

If you have problems with the operation of your scanner, please check the following troubleshooting hints.

8.1 FREQUENTLY ASKED QUESTIONS

Question: When the scanner is powered on, it makes noises and won't stand ready.

Answer: There are two possibilities:

1) You might fail to push the scanner shipping lock to its "use" position. If this is the case, pull the scanner status switch to its "use" position first.
2) The scanner is not placed on an even, flat desktop surface. This may cause the scanner to malfunction.

Question: The scanner is powered on, but the lamp does not light up.

Answer: The lamp is probably out of order. Contact your local dealer or distributor to replace the lamp. For your information, the average life time of the lamp is about 15,000 hours and the operating temperature for the scanner is between 10^(50^) and 40^(104^) .

Question: While scanning, the scanner often makes noises, or it scans back and forth.

Answer: Usually this means the memory of your computer is not enough or the speed of your CPU too slow. Please try to increase your memory to at least 32M or replace your CPU with Pentium or later.

Question: Why is it that the scanned image always comes out to be too dark?

Answer: 1) Modify the Gamma setting to 1.8 2.2 for your monitor and, when printing, set the Gamma setting to 2.2 for your printer.

2) Adjust the Brightness setting from the TWAIN user interface to get a brighter image.

Question: The scanner works well except for the line art image. The lines in the image seem to be much thicker than the original one.

Answer: Increase the Brightness or adjust the Threshold setting to improve line art image.
