Abstract
An automatic printing adjustment method for a page-width array printing device is provided. The page-width array printing device includes a printing module, a scanning module and a print region. Firstly, the printing module prints a print medium placed on the print region to obtain a printed image, and the scanning module scans the printed image of the print medium. Then, the printed image is transmitted from the scanning module to a processor. Then, a noise eliminating operation, a tilt calibration operation, a ROI selecting operation, a horizontal detection operation and a vertical detection operation are performed on the printed image. Afterwards, a calibrating result is feedback from the processor to the printing module. The printing conditions of nozzles of the respective inkjet head structures are adjusted according to the calibrating result.
