Features of the Scanner The main features of the scanner are described below. ● Compact Design The scanner has a compact size of 291 mm (11.46") (W) × 250 mm (9.84") (D) × 245 mm (9.65") (H). ● Fast Document Feeding Documents can be scanned at a speed of up to 40 pages per minute (A4 size, 200dpi). ● High Image Quality The 600 dpi optical resolution sensor incorporated in the scanner enables documents to be scanned with high image quality. ● USB 2.0 Interface The scanner supports Hi-Speed USB 2.0. ● Color/Grayscale Support Documents can be scanned in 24-bit color or 256-level grayscale. ● Supports a Variety of Scanning Modes The scanner supports the following scanning modes, depending on the document type: • Single-sided or double-sided scanning (with Skip Blank Page function) • Continuous or single sheet feed ● Card Scan You can scan business or ID cards. ● Paper Size Detection The scanner automatically detects the size of a scanned document and eliminates any unnecessary space around the edges of the image when storing the image, even when storing a document of irregular size. ● Auto Color Detection The scanner detects whether the scanned document is in color, grayscale, or black and white, and saves the image accordingly. ● Full Auto Mode A Full Auto Mode is provided in CaptureOnTouch and the scanner driver to allow scanning under automatically determined conditions. Scanning conditions such as the color mode and page size are set automatically based on the document being scanned. ● Auto Resolution Detection When enabled in the CaptureOnTouch or scanner driver settings, this function detects the content of documents and determines the scanning resolution automatically. ● Deskew The scanner is equipped with a deskew function that straightens images before saving them when documents are scanned askew. The scanned images are straightened, as opposed to the actual document sheets. ● Ultrasonic Double Feed Detection Ultrasonic waves are used to detect pages that are fed at the same time as well as the space between pages. Scanning stops if a double feed is detected. ● Double Feed Detection Ignore When a double feed is detected, the DFR button on the operation panel is lit. You can continue scanning by pressing the DFR button. ● Text Enhancement Modes The scanner is equipped with an Advanced Text Enhancement Mode to enhance the text of documents with dark or uneven backgrounds, and an Advanced Text Enhancement II mode to enhance the text when both the text and background are light. These modes may not work, depending on the type of document. ● Color Drop-out The scanner is equipped with a Color Drop-out function that enables you to specify a color for the scanner to omit from the scanned image during black and white or grayscale scanning. ● Skip Blank Page Function The scanner is equipped with a Skip Blank Page function that enables you to scan a document without storing images of blank pages, regardless of whether each page of the document is twosided or one-sided. Both sides are scanned, but saving the image is skipped for scan images judged to be from a blank page. ● Prescan Function The scanner is equipped with a Prescan function that allows you to adjust the contrast and brightness of a prescanned image and then send the adjusted image to the application software, without needing to scan the document again. 13
