    Abstract: A method of printing a document using one of a plurality of print modes, the method comprising: (i) notionally dividing a digital image of the document into sectors; (ii) for each sector, comparing one or more properties of the luminosity of pixels within each sector with one or more threshold values; (iii) using the comparison of (ii) to determine whether each sector is likely to show an image defect if printed at a lower image quality print mode; (iv) selecting a print mode such that all sectors are determined not to be likely to show an image defect; (v) printing the document using the determined print mode.

    Abstract: An original reader capable of being downsized without requiring a large-capacity image memory. A conveying path conveys an original. Sensors are arranged on the conveying path, for detecting the conveyed original. CCD line sensors read the conveyed original. A CPU of the image reader decides the size of the conveyed original based on the results of detection by the sensors. An image memory stores image data output from the line sensors. The CPU transmits the decided original size and the stored image data to a controller. When the CPU cannot decide the original size at a predetermined timing, it transmits one of original size candidates to the controller, as a provisional original size. When the size of the original decided afterwards is different from the provisional original size, the CPU retransmits the decided size of the original.
