Apparatus for discriminating print medium, image forming apparatus therewith, and process for discriminating print medium

摘要

The present invention is a media sensor comprises one of a light-receiving unit that detects the intensity of the light emitting unit and reflected light for the incident light for irradiating (照射) the first incident light intensity which gradually rises to the print medium; And, the print media identifying section for identifying the print media by the comparison of the reflected light intensity of the first reflected light by the first incident light and a predefined reference value; provides a print media identification system comprising the. ; In addition, the present invention, the printing device for printing an image on a printing medium, and a device having an image forming device to identify the printing medium having the above features. ; In addition, the present invention, the first sensing step to examine the first incident light intensity which gradually rises to the print medium to detect the intensity of the first reflected light of the reflected light; And, the print media identifying step for identifying the print media by comparing the intensity of the first reflected light and the predefined reference value; provides a printing medium identification method comprising the.
