    • A system CPU checks whether a copying mode is selected. If the copying mode is selected, the system CPU calculates “read area=periphery of original 2−mm×100÷magnification.” If the copying mode is not selected, the system CPU checks whether a resolution conversion is effective or not. If the resolution conversion is not effective, the system CPU calculates “read area=periphery of original−2 mm×100÷magnification.” If the resolution conversion is effective, the system CPU calculates “read area=periphery of original−2 mm.” The system CPU instructs the scanner CPU to start scanning with the calculated read area.
    • 系统CPU检查是否选择复印模式。 如果选择了复印模式,则系统CPU计算“读取区域=原始2-mmx100 /放大倍数的周边”。 如果未选择复印模式,系统CPU会检查分辨率转换是否有效。 如果分辨率转换无效,则系统CPU计算“读取区域=原始-2mmx100 /放大倍率的周边”。 如果分辨率转换有效,则系统CPU计算“读取区域=原始外围2mm”。 系统CPU指示扫描仪CPU以计算的读取区域开始扫描。
