Abstract: On a basis of a frequency analysis of the irregularities in density caused by a subscanning direction feed amount error of an exposure head, subscanning direction intervals between LEDs of the exposure head within the image forming apparatus are unequal such that the irregularities in density generated in an image is generated in high frequency area with a spatial frequency of at least 1 lp/mm. By using such image forming apparatus, an image is formed in which the irregularities in density is sufficiently suppressed in low frequency area with the spatial frequency of less than 1 lp/mm. Even if the irregularities in density is relatively large in high spatial frequency area, human eyes are difficult to view the irregularities in density thus the image quality can be improved.

Abstract: A printer includes a photosensitive drum which is exposed by a line head which includes a fluorescent head having a large number of light points which are aligned in a direction of a width of the photosensitive drum, and the respective light points of the fluorescent head are driven by a line driver in accordance with drive data from a shift register which holds the drive data for all the light points. One print line is formed by a set of four sublines. In a case where the thinning of a line width is corrected in a main scanning direction, the print line is formed by sublines more than five, whereby the line width is fatted.

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.
