Scan Settings Tab

To set the scan resolution for this job, enter the DPI required into the DPI text box. Use the Scan Mode drop down to select between colour, grayscale or black and white (binary) scans. In addition, there may also be additional proprietary modes in there related to scanner models.
The Text Enhance check box and associated drop down is used to select Canon’s Advanced Text Enhancement modes for black and white scanning. With this check box selected, the Brightness and Contrast sliders become available, allowing you to control the Canon scanner Advanced Text Enhancement function with customized accuracy. Use this setting to enhance the visibility of the text for OCR during the scanning process. The Colour Dropout and Colour Enhance controls allow for the disabling or boosting of the Red, Green and Blue scanners on Canon document scanners.
The following functions are Scan2x features that help to improve the quality of the final scan.
|
Feature
|
Explanation
|
|
Auto Scan
|
When enabled, this instructs the scanner to scan several documents that are fed through automatically without the need for the user to tell the scanner to scan the next document.
|
|
Auto Feed
|
If Auto Scan is OFF, Auto Feed ON will start scanning as soon as you put a paper in the scanner.
If Auto Feed is OFF, this will require the user to press the physical scan button on the scanner.
|
|
Duplex
|
When enabled, this instructs the scanner to scan both sides of the page simultaneously. A single sheet document with content on only one side will result in a two-page PDF, in which the second page is blank. See the Discard Blank Pages feature to automatically remove this blank page.
|
|
Auto Deskew
|
The nature of paper is such that individual pages or entire documents can sometimes pass through the scanner at an angle, resulting in a skewed image. The Auto Deskew feature attempts to digitally restore the image by analyzing the document content.
|
|
Crop Black Borders
|
This setting causes Scan2x to attempt to identify and crop out black borders from a document scan. The percentage setting allows for the adjustment of the effectiveness of this function.
|
|
Crop White Borders
|
This setting causes Scan2x to attempt to identify and crop out white borders from a document scan, like when scanning identity documents such as a driving licence. The percentage setting allows for the adjustment of the effectiveness of this function.
|
|
Folio Mode
|
When this checkbox is selected, Scan2x will combine the specified number of pages into one page. For example, one can scan an A3 image from two A4 images (e.g., an A3 document folded in two and scanned on an A4-capable scanner).
|
|
Booklet Mode
|
When this setting is selected, Scan2x will assume that the document being scanned is printed as a booklet. Each page in the booklet will be created on a different page in Scan2x, and all collation and page rotations are performed automatically by Scan2x.
|
|
Discard Blank Pages
|
By enabling this feature, Scan2x will selectively delete pages from those being received by the scanner if they are completely blank.
|
|
Allow Empty Document
|
By enabling this feature, Scan2x will allow empty documents to be scanned.
|
|
Detect Double Feed
|
Many scanner models have one or more ways to detect, and sometimes actively correct, double-fed documents. An unnoticed double feed is extremely dangerous to any document archiving activity as this will result in an incomplete document being unknowingly archived. Many scanners use ultrasonic beams to detect paper thicknesses and/or paper length monitoring to try and detect double feeds. Some can even reverse and ‘jog’ the incoming paper to perform a successful scan when a double feed is suspected. Enabling this function in Scan2x sets up your scanner to utilize whatever features it has to detect and prevent double feeds.
|
|
Reduce Bleed through
|
Scanning of a document involves passing the page between two scanner sensors that each shine light onto the page. Thin paper can sometimes allow the light from one scanner sensor to pass through it and interfere with the sensor on the opposite side of the sheet, compromising the image. Enabling this feature attempts to detect this phenomenon and eliminate it.
|
|
Scan to local scan queue
|
By enabling this feature, Scan2x will scan and save documents in the local scan queue which acts as a directory that can be used when importing documents for other jobs.
|
|
Auto-Save job
|
Job can be set to bypass document preview when all metadata fields are collected, and validations satisfied.
|
The Auto-save function allows for the short-circuiting of the document vetting screen, which displays the resulting document/s to the user after scanning but prior to saving. This short-circuit function is useful when the documents being scanned have some form of 100% reliable indexing mark (for example, a QR Code) that will be auto-indexed perfectly every time.
It is important that this function is not used when you require the user to check the metadata before saving.
The Auto Rotate function examines each page and will attempt to determine whether the page has been inadvertently presented to the scanner upside down. If this is detected, it will rotate the document by 180 degrees It does this by attempting to determine the orientation of text on the page, so pages with little or no text will not be auto rotated.
Some scanner models have the capability of autorotation internally without effecting their scanning speed – others slow down considerably if scanning a multipage document with auto-rotate enabled. Scan2x therefore provides a feature wherein you may choose if you wish to perform auto-rotation within the scanner hardware or in Scan2x. It is generally preferable to use the scanner hardware unless speed is compromised with your scanner model, as the process is generally faster – however, Scan2x auto-rotation feature provides a very acceptable alternative if required.
Some Canon high speed scanner models have imprinter options. Imprinters are small inkjet printers that can mark a sheet as it physically passes through the scanner, printing text on it that can be defined and customized through Scan2x using the Imprinter Text option. Obviously, this function will only work on printer models equipped with imprinter functionality and will be ignored for all other models.
It is sometimes convenient to deliberately present pages to the scanner upside down, or side-on. One reason might be document damage (e.g., staple holes at the top left of each document) that is causing your scanner to jam – by presenting your documents to be scanned upside down, the damaged part is fed into the scanner last, so it doesn’t jam. Another reason for presenting pages to the scanner side-on is speed - it is always better to present the long side of the document, if possible, as scanners run much faster this way. However, the reasons above mean that the scans produced are then not correctly oriented, and so Scan2x has a feature called Always rotate pages by, with a drop-down box to select the required angle of rotation. By using this function, ALL documents scanned are ALWAYS rotated by the selected amount. This feature is much faster than the auto-rotate function described above as no page content analysis takes place for each page scanned.
The OCR Engine dropdown allows you to choose between using different OCR engines. Scan2x is supplied with two OCR engines by default. The iDRS OCR Engine is a world-class engine from IRIS, used in products from companies like Canon, HP, Adobe, Panasonic, Samsung and LG. The Tesseract OCR engine is a tuned variant of the open-source Google Tesseract engine. For the use of either of these engines there are no additional charges. Your choice of OCR engine will then allow you to choose the language that you intend to recognize, using the OCR Language dropdown. Unless you have a specific reason for using Tesseract or Abbyy, we recommend you use the default iDRS engine setting.
