    Setting Basic Scanning Conditions
    ###HOME > Chapter 7 Setting the Scanner Driver > Setting Basic 
    Scanning Conditions###
    This section provides an overview of the basic setting items that are 
    the minimum requirements when configuring the scanner settings.
    Confirming Basic Conditions for Scanning
    When you scan a document, make sure you confirm the [Color mode], 
    [Page Size], [Dots per inch], and [Scanning Side] basic conditions in the 
    Basic settings dialog box.
    When you access the settings screen of the scanner driver from a 
    TWAIN compatible application, you can switch the settings screen 
    between Simple Mode and Advanced Mode screens shown below.
    Simple Mode Advanced Mode 
    						
    							65
    Color mode
    Select the scanning mode.
    z[Advanced Text Enhancement] and [Advanced Text Enhancement II] 
    remove or process the background color and background 
    surrounding text to enhance the text for easy reading. When 
    [Advanced Text Enhancement II] is selected, you can make the text in 
    scanned images easier to read by adjusting the contrast on the 
    [Brightness] tab.
    z[Detect automatically] detects whether the document is in color, 
    grayscale, or black and white. You can configure advanced settings 
    related to the detection method by clicking [Setting]. For details, see 
    the Help.
    Page Size
    Select the page size that matches the document to be scanned.
    If [Match original size] is selected, the edges of the document are detected 
    and images that match the size of the document are saved.
    Dots per inch
    Select the scanning resolution.
    Higher resolutions provide clearer images but result in larger file sizes and 
    slower scanning.
    When [Detect automatically] is specified, the resolution is detected 
    automatically from the content printed in the document.
    Scanning Side
    Select which of the sides of the document to scan.
    If the scanning side is set to [Skip blank page], the images of blank pages 
    are deleted when images are saved.
    Confirming Basic Conditions for Scanning
    When you scan a document, make sure you confirm the [Color mode], 
    [Dots per inch], [Page Size], and [Scanning Side] basic conditions in the 
    settings screen of the scanner driver. 
    						
    							66
    Color mode
    Select the scanning mode.
    z[Advanced Text Enhancement II] removes or processes the 
    background color and background surrounding text to enhance the 
    text for easy reading.
    z[Detect automatically] detects whether a document is color, 
    grayscale, or black and white based on its content. When this is 
    selected, you can configure detailed settings for the detection 
    method. Refer to the Help for details.
    Dots per inch
    Select the scanning resolution.
    zHigher resolutions provide clearer images but result in larger file sizes 
    and slower scanning.
    zWhen [Detect automatically] is specified, the resolution is detected 
    automatically from the content printed in the document.
    Page Size
    Select the page size that matches the document to be scanned.
    If [Detect automatically] is selected, the edges of the document are 
    detected and images that match the size of the document are saved.
    Scanning Side
    Select which of the sides of the document to scan.
    If the scanning side is set to [Skip blank page], the images of blank pages 
    are deleted when images are saved.
