PRINTER
Document Type and Number:
WIPO Patent Application WO/2011/040099
Kind Code:
A1
Abstract:
This printer is an apparatus for conducting color printing by an ink-jet system, and comprises a scanning mechanism for moving a printing medium in the direction of scanning, and an ejection unit for ejecting fine liquid droplets of an ink toward a printing medium being conveyed in the direction of scanning by the scanning mechanism. In the printer, an image-taking assembly takes an image of a page-identifier (95) printed on each page of the printing medium, and an inspection assembly compares the page identification result derived from the output from the image-taking unit with the image identification information contained in the printed data. The page-identifier (95) contains single color portions (951a-951d) printed with the respective ink of a plurality of colors used in the printer. Therefore, when a printing defect has occurred with any one color of the plurality of colors of the ink, the printing defect can be detected quickly in the inspection of the first page where the printing defect has occurred.
