    Scanner Model Panel Options
    The options in this panel are specific to the scanner you are using. If you select an option in this panel that also 
    appears on the Main panel, when you return to the Main panel, that option will be selected. Select the Advanced 
    source configuration mode to show this panel.
    Detect Double Feeds
    Detect double feeds is the scanner's ability to detect when two or more pages are fed through the scanner at 
    the same time. When this option is turned on, ultrasonic waves are aimed at the document to detect multiple 
    pages by the level at which the waves pass through the pages. The accuracy of this sensor depends on paper 
    thickness and whether or not creasing is in the original document.
    This option is available in the interface only if the current scanner supports this feature.
    Adjusting the sensitivity level
    Click on the scanner model panel to set the sensitivity level at which the scanner detects double feeds. Move the 
    slider left or right to adjust the sensitivity level.
    •Low works best with paper weight higher than 22lb (80 g/m2 or higher).
    •Normal works best with standard printer paper weight 18lb or 20lb (67 - 75 g/m2).
    •High works best with paper weight lower than or equal to 16lb (60 g/m2 or lower).
    Te c h n i c a l  N o t e :
    If you are getting false double feed errors, try cleaning the inside of the scanner. Excessive dust on the sensor can 
    cause false double feed errors. Refer to the maintenance section of the scanner's user guide for instructions on 
    cleaning the scanner.

    Detect Stapled Documents
    Select this option to have the scanner warn you if a stapled page has been detected. When the scanner detects 
    the stapled page it will stop scanning so that you can fix the problem and start the scan again.
    Skew Detection
    This option detects when a page has been fed through at an angle. Select an option from the drop menu to turn 
    on this feature. When scanning, always make sure the paper guides have been properly adjusted to the width of 
    the documents in the input tray. This helps to prevent the pages from being pulled through at an angle.
    Document Handling
    Select the type of paper in your scan batch.  Leave the default selection for Normal paper handling to have the 
    scanner feed items at normal scan speeds.  Select Delicate to have the scanner slow the feeding motor so that 
    very thin or fragile paper does not tear as it is fed through the scanner.
    Patch Code Action
    Select an option from this list to enable detection of patch code sheets while scanning. 
    •Detect and include—the scanner will detect the sheet and then retain an image of the sheet in the output 
    scan.
    •Detect and exclude—the scanner will detect the sheet and then discard the image of the sheet so that it is 
    not included in the output scan.
    The action that occurs when a patch code is detected is dependent on the scanning application you are using. 
    Patch code detection is an advanced feature and should only be used if you are already familiar with the 
    technology.
    Use the Search direction options to specify the orientation of the patch code sheet relative to the feed direction. 
    The scanner detects these sheets in the document stack as follows:
    • The scanner will only detect sheet data that faces the Simplex lamp module.
    Patch code sheets are available on the scanner’s installation disc for you to print and use.  The scanner can detect 
    patch codes 2, 3 and T. The file is located in the user guides section for the scanner on the installation disc. Print 
    the sheets that are appropriate for the size of the pages being scanned.  For instance, if you are scanning A4 
    pages, print the sheet that is in the bookmark for A4.
    Threshold
    Adjust the midpoint gray level for deciding what is black and what is white on a patch code sheet.
    Lower this value if your patch code appears on a darker background. Raise this value if your patch code appears 
    on a lighter background.

    Imprinter Panel Options
    Use the imprinter tab to set the options for printing data on the pages as they are scanned. The imprinter options 
    are only available if you have an imprinter unit installed in the scanner. Depending on your scanner model, you 
    may have two imprinter options in the TWAIN interface. Only the imprinter options appropriate for your scanner 
    will be available in the interface.
    Use imprinter—select this option to enable the features in the Imprinter tab for you to configure the text strings 
    you want to have printed on the page.
    If you are using a scanner that has two imprinters installed, select the imprinter you want to configure from the 
    list.  Only one imprinter can be used at a time, you cannot enable and configure both imprinters.
    •Pre-imprinter—prints the character strings defined on this tab on the pages before the pages are scanned. 
    These strings then appear in the scanned image. The pre-imprinter only prints on the simplex (face up) side 
    of the page.
    •Post-imprinter—prints the character strings defined on this tab on the pages after they are scanned. The 
    post-imprinter only prints on the duplex (back) side of the page.
    Text format template—input the text you want to have printed on the scanned pages.  The following table 
    shows the available alphanumeric characters and symbols that can be printed. A maximum of 72 characters can 
    be printed, which includes text you type in the input field as well as any tokens you select from the token list.
    To k e n s—click the down arrow and select a token from the list, then click the arrow button to add that value to 
    the character string field. You can add up to 3 tokens from this token list.  The amount of text you can type in the 
    Text format template field will be reduced by the number of characters that will be printed using the tokens you 
    selected.
    • {FN} – inserts the scanner name.
    • {User} – inserts the user name.
    • {Mach} – inserts the computer name.

    • {YYYY/MM/DD} – inserts the current date in the 4-digit Year/Month/Day format (2011/01/31).
    • {MM/DD/YY} – inserts the current date in the Month/Day/2-digit Year format (01/31/11).
    • {DD MMM.,YYYY} – inserts the current date in the Day, 3-letter Month, 4-digit Year format (31 Jan., 2011).
    • {HH:mm} – inserts the current time in hours:minutes using the 24-hour clock format (13:30).
    • {HH:mm:ss} – inserts the current time in hours:minutes:seconds using the 24-hour clock format (13:30:01).
    Orientation—select in which direction you want the text printed on the page. When you select an option from 
    the list, the text to the right shows a preview of how the text will look on the page.
    Ve r t i ca l  p o s i t i o n—drag the slider up or down to set the start position on the page where you want the text 
    printed. The starting position of the slider is 10mm (approximately .4 inches) as this is the minimum required 
    margin from the edge of the paper. You should set the paper size on the Scan Settings tab before adjusting the 
    Vertical start position. Click on the label “mm” or “inches” to switch between the two units of measurement.
    You set the horizontal start position by moving the ink carriage in the imprinter unit itself. Move the ink carriage 
    left or right and align the arrow tab to the appropriate paper width indicated on the imprinter unit.
    Counters—the options in this area allow you to set the unique counting numbers to be used in the printed text.
    •Counter digits—click the up or down arrows to change the number of digits to print in the counting number 
    string.  You can specify 1 to 7 digits, and you must add either the token {#_b} or {#0b} to the Text format 
    template field for these numbers to be include in the printed string.

    User’s Guide 7-138 •Start at—click the up or down arrow to change the first number printed on the first page.  The starting 
    number is limited to the number you set in the Pad to field.
    •Count by—click the up or down arrow to change how the numbers count.  You can set the count from 1 to a 
    maximum of 9 digits at a time.  For example, if you want the imprinter to print the number of images 
    scanned, and you are scanning in duplex, you can set the Count by number to 2 so that the printer string 
    reflects the number of images captured in the scanned file.  If you want to track the actual number of pages 
    scanned, set the counter digit to 1.
    For example, if you were to input in the text format template: Scanned {YYYY/MM/DD} – {#0b}
    With the fields set for Counter digits:6, Start at:500, and Count by:2
    The resulting printed character string for a pre-imprinter on 4 pages would be:
    • Scanned 2012/01/31 – 000500
    • Scanned 2012/01/31 – 000502
    • Scanned 2012/01/31 – 000504
    • Scanned 2012/01/31 – 000506
    Note that when using the token that inserts the 3-letter month {DD MMM.,YYYY}, the text inserted is the English 
    3-letter month abbreviation.  For example, 31 Jan., 2012.
    Tip: save the changes to a Preset when you are done setting the imprinter options.

    Brightness
    Brightness is the overall lightness of the image. Move the slider left or right to darken or lighten the image. 
    Adjusting the brightness level adjusts the tone of the pixels, without changing the true color of the pixels; such as 
    when adjusting hue. 
    Choosing brightness values
    Adjusting the brightness level is based on how you want the image to appear and there is no standard to adhere 
    to. Below are some recommended options for brightness image correction based on the original document 
    quality.
    • Original documents of good quality - 50%
    • Pencil written letters, forms, or drawings - 25% to 40%
    • Faded pictures or old documents with faded text - 35% to 45%
    • Light colored carbon copy paper, such as yellow or pale pink or pale green, with light text - 45% to 55%
    • Newspaper or magazine pages - 55% to 70%
    • Book pages - 55% to 80%
    • Pictures taken inside or in the shade - 60% to 85%

    User’s Guide7-141 Brightness works in conjunction with Contrast for image enhancement. When you are adjusting the brightness 
    level to improve the scanned image quality, try adjusting the contrast level as well. The contrast level is the range 
    between the lightest and darkest parts of the image. For example, if you scanned a document with notes written 
    in pencil, you may have to decrease the brightness level to get the handwritten notes to appear in the scanned 
    image. However, when decreasing the brightness, white starts to appear gray in the image. In that case, raise the 
    contrast level to make the differences between the lightest and darkest part of the image more defined.
    Color image brightness examples
    The examples below show the original image at the default setting of 50% brightness level, 25% brightness and 
    75% brightness. Adjusting the brightness level does not make the image completely black nor completely white.
    Technical note:
    Most monitors have a brightness setting that is user adjustable. When viewing scanned images on-screen, versus 
    printing the image, the brightness setting of the monitor may affect how light or dark the scanned image looks 
    when compared to the original. If the scanned image is too different from the original image, or if adjusting the 
    scanned brightness level does not modify the image how you want, try adjusting the monitor's brightness level. 
    Refer to the monitor's user guide for adjusting the brightness level and see if the manufacturer has any 
    recommended settings.
    Black background scanners:
    Some scanners have a black background plate. A black background results in more precise cropping results and 
    skew detection. However, when scanning thin paper, such as multipart color forms or ruled writing paper, which 
    are less than 18lb paper weight, the background may “bleed” through into the final image and make the image 
    darker than it should be. In that case, try adjusting the brightness level between 60% and 80%.
    Contrast
    Contrast refers to the differences between the light and dark portions in the image. Move the slider left or right to 
    decrease or increase the contrast levels. Increasing the contrast level emphasizes the difference between the 
    lighter and darker portions of the image, decreasing the contrast de-emphasizes that difference.
    Choosing contrast values
    While Brightness adds the same amount of gray or white to all pixels in the image, Contrast adjusts the pixels 
    based on the pixel color level. For instance, increasing the contrast level will add white to light colored pixels and 
    gray to dark pixels to make the difference between color levels in the image crisper. Decreasing the contrast level 
    will have the opposite affect, where light colored pixels are modified with gray and dark pixels are modified with 
    white to make the transition of colors in the image appear smoother.Brightness: 25% Brightness: 50% Brightness: 75%

    Contrast works in conjunction with brightness for image enhancement, when decreasing the brightness level, the 
    overall image becomes darker, in which case you may want to increase the contrast level so that the differences 
    between the lighter and darker portions of the image are clearer.
