Features of the DR-2020U Document Scanner
The main features of the DR-2020U document scanner are described
below.
● Multiple Methods for Documents Feeding
Depending on the type of document you intend to scan, you can use
the feeder, flatbed, or business card feeder.
● Fast Document Feeding
Scan multipage documents at up to 20 pages per minute (for single-
sided documents) using the built-in feeder. The scanner can detect
documents that are loaded into the feeder and begin scanning
automatically using the auto-start function.
● Flatbed
Use the flatbed to scan documents that cannot be scanned through
the feeder (thin documents, documents that do not feed smoothly,
magazines and thicker documents, etc.).
● High Image Quality
The 600 dpi optical resolution sensor incorporated in the scanner
enables documents to be scanned with high image quality.
● PC Power Link Function
The power of the scanner can be linked to be automatically turned
ON/OFF in accordance with the power of the computer.
● 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.
• Simplex and Duplex scanning (with Skip Blank Page function)
• Continuous or single-page feeding
● Card Scan
Feed and scan up to 15 business cards at a time using the built-in
business card feeder.
● 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 or
black and white, and saves the image accordingly.
● Deskew
The scanner straightens scanned images when it detects that the
document was placed askew.
● Text Enhancement Modes
The scanner is equipped with the Advanced Text Enhancement
Mode, for enhancing the text of documents with dark or uneven
backgrounds, and the Advanced Text Enhancement II mode, for
enhancing 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.
● 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 two-
sided or one-sided. During duplex scanning, page images are not
saved for sides detected to be blank.
● 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.
● Job Function
The scanner includes three job buttons for automatically scanning
and performing operations (up to ten operations, such as saving,
printing, or mailing, can be registered) on the scanned image.
● Scan First
Press the Job Start button to start CaptureOnTouch, which provides
simple scanning by following on-screen instructions.
Hint
Some functions may not be available depending on the software you
are using.
