摘要： An image forming apparatus divides image data into a plurality of image regions in a sub-scanning direction and performs predetermined processing on the image data of each divided image region so as to form an image on a recording medium. The image forming apparatus includes: a detection unit (503) that detects whether the image data of the image region is blank data; a storage unit (505) that stores the image data of the image region that has been subjected to detection; and a control unit (408) that controls whether to cause the detection unit (503) to perform the detection depending on a predetermined printing mode.

摘要： The number of dots per inch or resolution may be specified within an image on a document or within a postal indicia and later checked to determine if the image or document or the postal indicia has the correct resolution. The foregoing is accomplished by specifying that the image on the substrate (14) will be printed with n plus m dots per inch; rotating an ink jet head (11) having n nozzles per inch about an axis (13) parallel to a substrate by an angle theta so that the ink jet head will produce an image on the substrate having (n/cos theta) dots per inch; storing in a data center that the specified image will be printed with (n/cos theta) dots per inch; analyzing the image to determine if the image has (n/cos theta) dots per inch; and comparing the number of dots per inch in the analyzed image with the number of dots per inch stored for the specified image to determine if they have the same number of dots per inch.

摘要： A method is provided for processing an image to optimize print time of the image by a print apparatus based on the size of the image to be printed and the print pass thresholds of the print apparatus. A dimension of the image corresponding to the dimension along the sub-scanning axis of the image as it will be printed by the print apparatus is obtained, along with the corresponding number of print passes required to print the image. An analysis is performed to determine whether the size of the image could be reduced to require one less print pass by the print apparatus in printing the reduced image based on the proximity of the determined dimension to the range of dimensions that will result in one less print pass by the print apparatus. If the size of the image may be reduced such that the image could be printed in one less print pass while also meeting optional criteria such as enforcement of a maximum image reduction threshold, the image is scaled prior to printing to reduce the number of print passes performed by the print apparatus in printing the image.

摘要： An image forming apparatus for simultaneously conducting multiple lines of exposure by scanning multiple laser beams from multiple light sources onto an image carrier in a main scanning direction, including: multiple light sources which are driven to emit laser beams based on image data; and a control section capable of controlling an image formation in two types of image forming modes of a first image forming mode where an image is formed at a first image forming speed by using all the multiple light sources, and a second image forming mode where the image is formed without using at least one of the multiple light sources at a second image forming speed slower than the first image forming speed, wherein the control section controls a light source which is not used in the second image forming mode to emit a laser beam onto outside of an image area.

摘要： A method for correcting scanning errors in a shuttle scanner is described. A pattern sheet on which pattern data having a specified shape are recorded is scanned. Errors for incline of the pattern data are corrected by using pattern data of a straight line form among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using pattern data of a specified shape. Accordingly, since the errors for incline and the errors for distance between the bands can be corrected by using a computer program, correcting the errors of the pattern data is very simple. Furthermore, even if the scanner is subjected to an impact from an exterior, correcting the errors for incline and the errors for distance between the bands can be promptly performed.
