  • Method and apparatus for selection of data packets in double sided scanning
    Patent number: 5303070
    Abstract: An image processing apparatus adapted to scan both sides of a document simultaneously in independent, arbitrary areas as directed by a host computer. When both sides of the document are read, the CPU and firmware ROM select the order of the output image data to maximize the image data throughput to the host computer. The image data is sent to the host computer in packets which are limited in size based upon corresponding limitations in the host. A typical such limitation is a maximum of 65,535 bytes including the header which identifies various parameters relating to the scanning process.
