  • Patent number: 7278704
    Abstract: An image forming apparatus having an image forming part that forms an image on a recording medium measures, downstream of the image forming part in a transport path of the recording medium, speckles on the recording medium, and generates measured speckle data that represents speckles measured; stores the generated measured speckle data in a memory part, further measures, upstream of the image forming part in a transport path of a recording medium, the speckles of the recording medium; determines whether speckle data representing speckles analogous to speckles measured upstream of the image forming part is stored in the memory part, and, in the case where the decision result is affirmative, recognizes that the recording medium for which the speckles have been measured is a recording medium on which an image has been formed on it previous to having speckles measured upstream of the image forming part.

  • Patent number: 7062183
    Abstract: The present invention provides a recording media identifier for identifying types of recording media, and a recording device, provided with a recording media identifier, which records images by printing on recording media. A speckle measuring section of the recording device measures a speckle on a recording medium conveyed on a conveyance path. Types of recording media are detected through correlation of the speckle measured with speckles stored in a storage section, in a manner in which the speckles correspond to types of recording media. Recording and fixing conditions of the recording device are adjusted according to the types of the recording media detected.

  • Patent number: 7058323
    Abstract: An image forming apparatus with an image forming part and a fixing part for fixing images on a recording medium measures, downstream of the fixing part in a transport path, speckles on a recording medium, and generates measured speckle data representing the measured speckles; stores measured speckle data with standard speckle data representing speckles on a recording medium that has not undergone a fixing process; further measures, upstream of the image forming part, measures speckles on a recording medium; and when the stored standard speckle data is the most analogous to speckles measured for the second time, applies corrections in order to compensate for the lengthening of the recording medium by a fixing process to document images formed thereon, and when the stored measured speckle data is the most analogous to speckles measured for the second time, does not perform the corrections in order to compensate for the lengthening.
