Basic Scenarios This section provides three basic scanning scenarios with ScanWizard DI, including scanning a stack of paper, scanning a single-sheet document, and performing multiple-frame scanning. Details on how to adjust images are discussed in later chapters. A. How to Scan a Stack of Paper 1. Place the stack of paper to be scanned on the document feed tray. 2.
If ScanWizard DI is launched as a stand-alone program, the scanned image can be saved after the scan to a file, opened in an image-editing program, or sent to a printer. Toolbar Scanning settings Image type Scan frame (enclosed by dotted lines and labeled with the tag “Main”) Image correction settings Preview image (the enclosed frame bordered in red) Preview window For preview purposes only, take note of the additional notes below: 1.
B. How to Scan a Single-sheet Document 1. Place the single-sheet document to be scanned on either the scanner glass surface, or from the ADF’s document feed tray. 2. Launch ScanWizard DI (either as a stand-alone by clicking on the program icon, or by using the File-Import or Scan command from an application program. 3. Specify your scanning requirements in the ScanWizard DI control panel once ScanWizard DI is launched. a) Select your image output device (e.g., Flatbed) in the Scan Source.
7. If necessary, adjust image quality using the image correction tools. 8. Click the Scan or Scan To button to start scanning. If ScanWizard DI is launched from an image-editing program, the scanned image is delivered after the scan to your application, where the image can be saved, printed, or modified further. If ScanWizard DI is launched as a stand-alone program, the scanned image can be saved after the scan to a file, opened in an image-editing program, or sent to a printer.
C. How to Use Multiple Frames 1. Place the single-sheet color print to be scanned on either the scanner glass surface, or from the ADF’s document feed tray. 2. Launch ScanWizard DI (either as a stand-alone by clicking on the program icon, or by using the File-Import or Scan command from an application program. 3. Specify your scanning requirements in the ScanWizard DI control panel once ScanWizard DI is launched. a) Select your image output device (e.g., Flatbed) in the Scan Source.
b) Select Line Art in the Attribute as your image type for the selected frame. c) If necessary, adjust image quality using the image correction tools. 10. Click the Scan or Scan To button to start scanning. If ScanWizard DI is launched from an image-editing program, the scanned image is delivered after the scan to your application, where the image can be saved, printed, or modified further.
Preview button The Preview button scans a page based on the settings on the ScanWizard DI control panel, and displays the preview image on the preview window. You can then frame the image you need and click the Scan button to complete the final scan.
Scan To Scan To button: This is the default button when ScanWizard DI is launched as a standalone program (e.g., launched from the Start menu or the ScanWizard DI icon on the desktop). It performs the final scan and delivers the output to a specified application. When the “Scan To: Save As” dialog box appears, key in a file name, then select .tif, .bmp, .pcx, .dcx, and .pdf as the export file format. File name: This is the file name to store images.
When the Scan Type in the Settings window is set to “RGB Color” or “Grayscale,” and you select “PDF” as your “Save as type” in the “Scan To: Save As” dialog box and then click the File Option button, the “PDF Save Options” dialog box will appear. • Encoding: The encoding options include ZIP and JPEG. If ZIP is selected, image quality compression will not be available for adjustment.
OCR OCR button: Click the Scan To button and hold down the mouse until the Options menu appears, then select OCR. The document text is scanned, converted, and saved in text file format. When the “OCR: Save As” dialog box appears, key in a file name, then select .rtf, .txt, .xls, .htm, and .pdf as the export file format. File name: This is the file name to store documents. Save as type: This menu box lets you select a file format when saving a file; RTF is the default file format.
Toolbar The toolbar has buttons for executing certain tasks. The toolbar includes Select Frame, Pan, Zoom In, Zoom Out, Create Subframe, and Delete Subframe. Select Frame tool The Select Frame tool allows you make the frame selection and adjust the size of the frame for enclosing your final scan. To select a frame, click the Select Frame tool button, then click on the frame you want to select.
Zoom Out tool The Zoom Out tool reduces your view of the preview image, allowing you to set the scan frame with greater precision. Only the view size of the preview image is changed; the actual output size of the image remains the same. The reduction levels decrease from 400%, 300%, 200%, to 100%. Create Subframe tool The Create Subframe tool lets you create a new frame within the main frame. This feature allows you to create as many frames as you wish, and each frame can then have its own settings.
Scan Source Allows you to select the image input device. Three options for choosing the image device are available (depending on the scanner model): “Flatbed”; “Flatbed” and “ADF (Simplex)”; ADF (Simplex) and ADF (Duplex)”. If the ADF (Automatic Document Feeder) is not installed, “Flatbed” is the sole selection. Scan Type Allows you to select the image type for the scan when it is output. Select from RGB Color (24 bits), Grayscale (8 bits), and Black & White (1 bit).
The resolution of an image is important in determining the quality of the output image. Resolution is also directly related to file size; and the higher the resolution, the larger the resulting file size will be. When dealing with resolution, remember to distinguish between optical resolution and interpolated resolution. Optical resolution is the “real” resolution as measured by the scanner’s optics.
Frame Settings Allows you to set different frame settings. The options for frame property settings include: Attribute, Coordinate Position (X, Y), Image Size (W, H), Unit of Measurement, Image Correction tools, Default button, and Advanced buttons. Attribute The Attribute allows you to select the image type of the selected frame. Options include Photo, Line Art, and Text. Photo Photo images are image originals that use three colors (Red, Green, and Blue), or are grayscale images.
Coordinate Position (X, Y) The Coordinate Position shows the X/Y coordinates of the selected frame, starting from the upper left corner of the frame in the preview window. To move the selected frame to another position, enter the values manually in the X and Y edit boxes; or use the Select Frame tool and manually move the frame to a new position. Changes made in the preview window are automatically displayed in the X, Y edit boxes.
Image Correction Settings Image correction tools let you adjust the image attributes in ScanWizard DI. Work with the image correction tools to see how they optimize your results. ScanWizard DI supports these image correction tools: The availability of image correction tools depends on the Scan Type and Attribute of the image.
Threshold The Threshold control is active only when the Attribute setting of the selected frame image is Line Art. The default Threshold is preset to 128. To change the default Threshold setting, you should disable the “Auto Threshold” setting in the Advanced Setting window. To do this, click the Advanced... button to open its window, uncheck “Auto Threshold”, and click OK. Then return to the main control panel to drag the slider, or enter a desired value in the Threshold edit box.
Brightness/Contrast The Brightness/Contrast control is active only when the Attribute setting of the selected frame image is Photo. Brightness/Contrast lets you control the brightness and contrast levels of the selected frame image. Increasing the brightness makes all tones in the image lighter. Contrast, on the other hand, is the range between the darkest and lightest shades in the image, and increasing the contrast makes for greater separation between the darkest and lightest areas of the image.
Sharpen The Sharpen filters let you apply or create special sharpening effects to your selected frame images. The Sharpen filters include None, Sharpen, Sharpen More, Edge Enhancement, and Unsharp Masking. In using any of the sharpen filters, keep in mind that the image you obtain in the preview window may differ from the way the image appears when you finally scan it in. The appearance of the image in the preview window and how it is affected by a sharpen filter will depend on the resolution of the image.
Unsharp Masking The Unsharp Masking filter is used to adjust the contrast of edge detail, creating the illusion of more image sharpness. This filter can be useful for refocusing an image that has become blurry from interpolation or scanning, and it is an essential tool for doing CMYK color separation. In general, Unsharp Masking is needed to render sharp color reproductions, especially when you wish to make a large color reproduction from a small original.
Descreen The Descreen feature lets you remove moiré patterns from printed materials. Moirés occur when you scan a screened original (mostly reflective or previously printed material, such as pictures from a newspaper or magazine). These patterns appear to the naked eye like a series or grid of dots or as shown in the example below. Before After To set the screen for your needs, follow the steps below: 1. Click the Descreen options menu. 2.
Default button The Default button cancels the changes you have made with the image correction tools. This means that if you used several image correction tools (Brightness, Contrast, Hue, Saturation, Sharpen, and Descreen), all the image correction settings will be cancelled, and settings are restored to original factory-set values. Advanced...
Auto: When you check this option, the Shadow/Highlight value is automatically given according to your preview image. To manually adjust Shadow/Highlight, uncheck the Auto option. Shadow: Drag the black (left) triangle, or enter the value in the edit box to control the shadows. Moving this triangle to the right will emphasize shadows and create a darker image. Acceptable ranges are from 0 to 252. The default is 0.
Endorser The endorser function lets you print the endorser string (i.e., dates, name, and transaction codes) specified in this window on the backside of your original document for future retrieval. The Endorser control tab appears only when the scanner you are using implements the endorser function and when the current working frame is “Main Frame”. Enable Endorser: This enables the scanner to print the endorser string on the backside of the scanned document.
3. Press the Add button, then OK. The customized string will be added to the Format list for selection. To remove an unwanted customized string, select it from the Format option menu, then press the Delete button to remove it. Double Feed This function detects when two or more pages have been fed into the scanner at the same time, which helps prevent lost images when scanning larger batches of documents.
MICR The MICR function allows the scanner to convert a scanned MICR (Magnetic Ink Character Recognition) codeline into a text string that can be saved as a file for future retrieval. The MICR control tab appears only when the scanner you are using implements the MICR function and the current working frame is “Main Frame”. Magnetic ink character recognition: This enables the scanner to convert MICR codeline into a text string. If unchecked, a scanned MICR codeline will not be recognized from the document.
The File Menu Load Settings This command lets you load image setting templates that you have saved, with the file name having the file extension .set. Loading the same image setting is useful if you consistently work in a specific format, scan the same kind of the images, or if the scanner is shared for use with others who have their own image settings. Save Settings This command lets you save current image settings as a template file, with the file name having the file extension .set.
This command provides three functions (Scan To, Copy, and OCR), allowing you to specify the programmable button function on the scanner. • Scan To page The Scan To page is the default page when this command is first activated. It allows you to define a function button as a set of scan settings. When you have completed the settings on this page, press the corresponding function button on your scanner, and the scanner will automatically scan and save your images based on your settings on this page.
• Copy page The Copy page allows you to define a function button much like a conventional copier with your printer. When you have completed the settings on this page, press the corresponding function button on your scanner, and the scanner will scan the image and send it directly to your default installed printer, based on your settings on this page. Current Printer: Shows the default printer. To change the printer, click the “Setup...” button next to the printer name.
Save in: This is the folder name to store images. To specify a folder name of your own, click the folder icon next to the “Save in” string. File prefix: This edit box lets you enter a beginning string for a file name. “Document” is the default root file name. Start file #: This edit box lets you enter a beginning number for a file name. “00001” is the default. File format: This menu box lets you select a file format in saving; RTF is the default file format.
The Scanner Menu Get Current Scanner Info This command displays information about your current scanner. When you choose this command, a dialog box appears showing the scanner model, scanner ID number, firmware version, and the equipment. Scanner Control This command lets you specify a lead time for turning off the scanning lamp, thus saving power. The dialog message “Auto Power Saving mode if idled for N minutes” allows you set the idle time. By default, the idle time is 15 minutes.
Visible: The frame is marked with a check, indicating that the frame is visible in dotted lines in the preview window. The frame is visible by default. To hide the frame selection in the preview window, click the check mark again. If the frame Before After is unchecked, the frame cannot be selected in the preview window. Take note that the main frame is always visible in the preview window. Name: Shows the name of the frame.
