    Abstract: The invention is directed to a method of printing on a print medium wherein a relocation error is induced in a paper transport system so as to randomize, bias, or redistribute harmonic errors associated with the paper transport system. The print medium is advanced in the ink jet printer in an advance direction to a registration location using the paper transport system. A first subset of an addressable set of ink emitting orifices in the printhead are used to print on the print medium at the registration location. The print medium is then moved in a reverse direction a predetermined distance. The print medium is again advanced in the advance direction and relocated at the registration location using the paper transport system. A second subset of the addressable set of ink emitting orifices in the printhead are used to print on the relocated print medium at the registration location.

    Abstract: A vibration preventive system in use with an image recording apparatus of the type in which an original is scanned by reciprocatively moving an imaging unit by a stepping motor in two different types of scan modes, a forward scan mode in which an original read region is a constant speed region and a back scan mode to return the imaging unit to an original position at a high speed, the vibration preventive system comprising a drive current control for controlling a drive current fed to the stepping motor in such a way that in the constant speed region, drive current for driving the stepping motor is changed to a value smaller than that in an acceleration region. In the forward scan mode, the drive current is changed before the imaging unit reaches the registration position or after the end of acceleration in the forward scan mode. When the imaging unit is between them, the drive current is changed at a point in the undershoot of a transient vibration after the end of acceleration, or at the tail edge of the forward scan mode.

    Abstract: An additional motion is introduced into a scanning operation. This additional motion is in addition to the motion that is inherent in any document scanning operation. For example, in a flatbed scanner a linear array of scanning devices is positioned across the document in a first or “x” direction and this array is moved across the document in a perpendicular or “y” direction. In a flatbed scanner the position of the scanning devices are fixed in the “x” direction. In a drum scanner a light beam moves across the document in an “x” direction and the document is moved in the “y” direction. The light reflected from the document is directed to a fixed photoreceptor. With the present invention an additional vibratory motion is introduced into the scanning process. With a flatbed scanner the array of detector devices is moved or vibrated. The vibratory motion can for example be in the “x” direction. With a drum scanner the photoreceptor is moved or vibrated. For example the photodetector can be moved or vibrated in the “x” direction. The amount and direction of the vibratory movement can vary up to about one half the distance between units in the scanner's resolution (i.e. one half a pixel). If one is trying to eliminate Moire patterns the vibratory movement can be a pseudo random series of movements. If one is trying to introduce a special pattern into the document or to otherwise create special effects, various other type of motion can be used. Movement of the CCD array in a flatbed scanner or movement of the photoreceptor in a drum scanner can be done by a simple piezo electric transducer or by a simple mechanical cam.

    Abstract: A device and process which eliminates potential moiré patterns in digitized images by employing a one-dimensional sensor array and a sampling method of the sensor signals which produces a data set of non-uniformly spaced sensor positions. This allows the spacing of the sensors to avoid having a strong “harmonic” which may interfere with details or harmonics present in the image source, which eliminates the occurrence of moiré patterns and the need for application of image processing to remove moiré patterns. Sensors are non-uniformly spaced along a first axis according to a predetermined scheme or function. Sensors are sampled during scanning according a non-uniform function in order to realize a non-uniform sampling scheme in a second dimension. Linear interpolation is applied to the non-uniformly spaced data set, synthesizing a uniformly-spaced data set for use in common imaging formats and processing.
