● 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. ● 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. ● Text/Line Thickness Correction Function This function corrects the thickness of text and lines when the text and lines are not easily distinguishable in scanned images. ● Card Scanning You can scan credit cards and IC cards that conform to ISO standards. ● Passport Scan You can scan passports using the optional carrier sheet (for passports). ● 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. ● Auto Start The scanner is equipped with an auto start function, which enables scanning to be automatically started when a document placed in the feeder is detected. 20 Chapter 1 Before Use
