摘要： A control system for a charge deflection type ink jet printer which prints out one character line of print data by a plurality of strokes on a paper is disclosed. Data associated with odd scanning lines are printed out by one printing stroke of a carriage, then the paper is fed by a predetermined amount, and then data associated with even scanning lines are printed out. Thereafter, the paper is fed by an amount produced by subtracting a number of dots corresponding to a predetermined number of odd or even scanning lines from a number of dots corresponding to the total number of the odd and even scanning lines.

摘要： A method for a charge control and multi-step deflection control type ink jet printer is disclosed which renders halftone by multi-step gradation. When an ink ejected from a nozzle is to be charged, a charging voltage is suitably varied to cause a shift in deflection by a pitch smaller than one dot pitch in the deflection direction, thereby selectively causing dots in the deflection direction to overlap and separate from each other. The pitch for developing the shift is variable to control the overlapping or separating degree of the dots in order to accomplish gradation in numerous densities.

摘要： A deflection control ink jet recording apparatus is capable of compensating for dislocation of dots at all the deflection steps. A deflection amount is adjusted with respect to two points to determine a correlationship between the amplification gain, charge code and deflection amount, so that an amplification gain and a charge code free from dislocation is set for each deflection step. A charge code compensation value is detected to add it to or subtract it from a predetermined charge code assigned to each deflection step, thereby setting a charge voltage code to be assigned to each deflection step in a printout operation.

摘要： An ink jet head prints an image by superposing individual dot matrices of at least two colors. A computing unit receives electrical input signals representing the image and generates and feeds corresponding electrical signals representing the individual matrices of the at least two colors to the head means for printing. The computing means includes matrix generator means for generating the matrices in such a manner that the total number of dots to be printed in all of the matrices is limited to a first predetermined value which is less than the maximum possible total number of dots which can be printed in all of said individual dot matrices, and the total number of dots to be printed in the matrices which are formed by superposed dots of different colors is limited to a second predetermined value which is less than said first predetermined value.

摘要： An image is formed by dividing rasterized original image data into regions in accordance with N recording heads, and scanning a recording body by simultaneously irradiating recording beams from the N recording heads. Corrected image data divided into regions in accordance with the recording heads are generated by changing the rasterized original image data based on information including positional displacements of the recording beams, so that the positional displacements are corrected. Scanning information is generated based on the positional displacement information. The scanning information includes positions and orders for the recording beams to scan the recording body to record the corrected image data.

摘要： An image reader for an image forming apparatus has an array of CCD sensors in the form of chips which are arranged in a zigzag configuration along an image reading line. A reference white plate is located in association with the position of and outside of the effective image reading range of one of two CCD sensors which are situated at opposite ends of the array. The CCD sensor with which the reference white plate is associated produces a reference white signal by reading the reference white plate. The output gain of this CCD sensor is controlled on the basis of the reference white signal. The reference white signal is added to output signals of the other CCD sensors in the form of a pilot signal, whereby the output gains of the other CCD sensors are controlled.

摘要： An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.
