    Character recognition is usually improved in the following ways:

    – if capturing TWPT_BW, make sure automatic thresholding is on, if available, and turn on noise removal

    – if capturing TWPT_GRAY, capture the data either TWCP_NONE, or if using TWCP_JPEG, make sure the ICAP_JPEGQUALITY is at a high setting

    – select an ICAP_X/YRESOLUTION that evenly divides into the ICAP_X/YNATIVERESOLUTION for the scanner.

    – set ICAP_AUTOMATICDESKEW to TRUE, if available

    – if ICAP_AUTOMATICROTATE is available, trying turning it on to get the character in the correct orientation

    – if the desired text is black on a color document, consider using ICAP_FILTER to remove color content
