  • Patent number: 7331647
    Abstract: An apparatus and method for printing images on both sides of a recording medium. The timing of starting conveying the next recording medium is determined from a schedule that satisfies three conditions. The first condition a leading end of the next medium reaches a housing section, while maintaining a page gap, when the medium passes completely through the housing section. The second condition both media are not at a recording-medium supply position and the leading end of the next medium reaches the supply position, while maintaining a page gap, when the medium passes completely through the supply position. The third condition when the medium is turned upside down, both media are not at a reversing path section, and the leading end of the next medium reaches the reversing path section, while maintaining a page gap, when the medium passes completely through the reversing path section.
