    Abstract: An optical module positioning method for an image processing device is provided. The image processing device includes a scanning platform and an optical module. The scanning platform includes a first region, a second region, a third region and a fourth region. The fourth region is arranged between the first region and the second region. The first region is arranged between the third region and the fourth region. The optical module positioning method includes the following steps. Firstly, the optical module is driven to perform a scanning operation to acquire a scanned image while the optical module is not moved. Then, by judging the color values of two ends of the scanned image, the region where the optical module is stayed can be recognized according to the associated color values.

    Abstract: A printing device includes a sheet placement plate, an ejection roller module and an ejection control module. The ejection roller module is located near the sheet placement plate to eject at least one paper sheet. The ejection control module is connected with the ejection roller module. The ejection roller module is selectively in a released state or an ejection state under control of the ejection control module. When the ejection roller module is in the released state, the at least one paper sheet is transferred to the sheet placement plate through the ejection roller module. The ejection roller module is in the ejection state, the at least one paper sheet is outputted by the ejection roller module.
