Chapter 1 Before Use
● Text Enhance Mode
The background color of the text are processed to
enhance the text portions and make them easy to read.
* This function may not work effectively for some documents.
● Double Feed Detection by Length
When the scanner detects a double feed by comparing
the lengths of documents, it stops feeding.
* Using the length of the first document as a reference, the
scanner detects a double feed when a document of a
different length is fed.
● Skip Blank Page Function
The scanner scans both sides of a document and skips
saving the image of any side it determines to be a blank
page.
● Deskew
If the scanner detects from a scanned image that the
document was fed askew, the image is straightened.
● Image Rotation
The scanner can rotate a scanned image in 90°
increments, or detect the text orientation within the
document, and then rotate the image in 90° increments
so that the orientation of the text is correct.
● Eliminates Bleed-Through
The scanner prevents the images on the reverse side of
thin documents from appearing on the scanned pages.
● Dropout and Color Enhancement Functions
The scanner is equipped with a dropout function that
allows you to specify one color (red, blue, or green) to
omit, and a function to enhance a specified color when
scanning.
● Card Scanning
You can scan credit cards and IC cards that conform to
ISO/JIS standards.
● Prescan
This function prescans the first page of a document at
the start of scanning, and then stops scanning so that
you can view the results to adjust the brightness and
contrast before scanning the entire document.

● Fingerprint Authentication
The authentication system that uses a fingerprint sensor
to authenticate users enables you to log in to the
ScanFront 220P without entering your user name and
password.
● Double Feed Detection by Ultrasonic Function
In addition to the double feed detection function that
compares the lengths of documents, the scanner is
equipped with a double feed detection function that uses
an ultrasonic sensor.
