The concept of using a self-reliant and regular TWAIN module consequently tailored to the needs of a particular manufacturer offers many advantages to the user and his daily scanning work. CFM TWAIN not only permits using the basic functions of scanners, but also enables the other important functions and options inherent in every scanner model to be fully exploited. This is of special interest to users operating on the PC platform under Windows. Everything that can be done on the scanner’s "hardware level" saves computing time and reduces memory requirements.
