    • Whether a job-lock function is enabled is determined. Whether a current mode is a mode for outputting an image of an area on an original document onto a recording paper is determined. When the job-lock function is determined to be enabled, and when the current mode is the mode for outputting the image of the part of the area of the original document on the recording paper, the image of an area larger than the part of the area is read. It is possible to improve accuracy of recognizing a copying protection pattern, and to improve security, even when density unevenness is present on a copying prevented original document.
    • 确定是否启用作业锁定功能。 确定当前模式是否是用于将原始文档上的区域的图像输出到记录纸上的模式。 当确定作业锁定功能被使能时,当当前模式是用于将原始文档区域的一部分的图像输出到记录纸上的模式时,大于图像的部分的图像 区域被读取。 即使在复制防止原稿上存在浓度不均匀,也可以提高识别复印保护图案的精度,提高安全性。
