摘要： In a color image forming apparatus, component color images formed by respective image forming stations are sometimes displaced as they are transferred onto recording paper. Therefore, a set pattern image (Q0) with no displacement at all is recorded onto recording paper as a set pattern image (Q1). In this set pattern image, the centers of auxiliary patterns (Y1, C1, M1) are displaced in an auxiliary scan direction off a referential straight line (H) passing through the centers of primary patterns (K1, K1null). The image forming apparatus causes the set pattern image to be read, measures the displacements (nullY1, nullC1, nullM1) of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and adjusts writing timings in the auxiliary scan direction so that the displacements become 0. As a result, the color image recorded on the recording paper shows improved quality. Therefore, the resist of the component color images can be corrected by measuring the displacements of the component color images without being affected by a tilt of the patterns on the recording paper or irregularity in operation of the image forming stations for recording the component color images.
摘要翻译：在彩色图像形成装置中，由各个图像形成站形成的分量彩色图像在被转印到记录纸上时有时会移位。因此，完全没有位移的设定图案图像（Q0）被记录在记录纸上作为设定图案图像（Q1）。在该设定图案图像中，辅助图案（Y1，C1，M1）的中心在辅助扫描方向上偏离通过主图案（K1，K1'）的中心的参考直线（H）。图像形成装置使得设置的图案图像被读取，测量辅助扫描方向上的辅助图案离开参考直线的位移（DELTAY1，DELTAC1，DELTAM1），并且调整辅助扫描方向上的写入定时，使得位移变为0.结果，记录在记录纸上的彩色图像显示出提高的质量。因此，可以通过测量分量彩色图像的位移而不受记录纸上的图案的倾斜的影响或用于记录分量彩色图像的图像形成站的操作的不规则性来校正分量彩色图像的抗蚀剂。

摘要： The object of the present invention is to appropriately determine an attribute of a synthesized pixel at the time of synthesizing processing. An attribute of a pixel, synthesized based on a transmissivity null of a source pixel, is determined in the following manner. A threshold value T is obtained from attribute designation data (S603), the transmissivity null is compared with the threshold value T (S604), and if the transmissivity null is larger than the threshold value T, an attribute of a destination pixel is determined as the attribute of the synthesized pixel (S605), while if the transmissivity null is smaller than the threshold value T, an attribute of a source pixel is determined as the attribute of the synthesized pixel (S606).

摘要： A printer includes LED heads and head controllers. Each head controller transfers items of data to a corresponding head over a set of common buses. The LED head has a receiver activated by a corresponding head selecting signal. In one configuration, the common buses may include a selector bus over a data bus. Image data and a group of signals are alternately transferred over the data bus, the group of signals including a latch signal for latching the image data into a corresponding head and a strobe signal for driving a corresponding head in accordance with the image data. The selector signal allows the receiver to direct the image data and the group of signals into separate data paths. In another configuration, the control signals may further include an image clock and a control clock. The common buses may include an image clock bus, a control clock bus, and a data bus over which the image data and the group of signals are alternately transferred, the image data being attended by the image clock and the group of signals being attended by the control clock. In still another configuration, the image data may include a train of image data in which first image data and second image data appear alternately. One receiver receives the first image data on the rising edges of the image clock and another receiver receives the second image data on the falling edges.

摘要： The memory capacity required for temporarily holding image data with respect to a printer is reduced, and loads involved in supplying image data, such as decoding and conversion processes, are dispersed and reduced. The apparatus divides image data in parallel with a main scanning direction by an image divider, stores the divided data in image data memory, and supplies the divided image data to image data temporary memory by an image data supply to perform a decoding process. In order to provide a matching with a process speed, the image data temporary memory temporarily retains the divided image data, and a printer prints an image on a sheet of paper on the basis of the divided image data stored in the image data temporary memory. A predictor predicts a supply process time by way of image data supply, and an image data supply control causes the image data supply to start the supply process of the divided image data at a time preceding the time for the start of the print process by the printer according to the time predicted.

摘要： Developing devices are provided adjacent to a light sensitive element. An intermediate transfer drum is provided adjacent to the light sensitive elements. After exposure of the light sensitive element, a first color or third color image is formed on the light sensitive element. On the other hand, after exposure of the light sensitive element, a second color or fourth color image can be formed on the light sensitive element. The first color image is transferred from the transfer unit to the intermediate transfer drum at the first transfer portion, and the second color image is transferred from the transfer unit at the second transfer portion so as to be superimposed on the first color image. Similarly, the third color image is transferred so as to be superimposed on the second image and the fourth color image is transferred so as to be superimposed on the third color image to the intermediate transfer drum. Accordingly, the first to fourth color images are superimposed. Thereby, downsizing of the device and cost reduction are achieved and image formation speed is facilitated.

摘要： A full-color printer which reduces toner consumption by lowering the overall image density without changing the overall image tonality. An invalid data masking unit 31 masks non-printing area of a image signal 39 outputted from a FIFO buffer 30, and outputs the masked image data into a toner-saving image converter 32. The toner-saving image converter 32 zigzag masks the image signal every other pixel in main-scanning and subscanning directions based on a toner-saving mode designation signal A from a CPU 38. The masked image signal density is "00[H]". Thereafter, a .gamma. corrector 35 .gamma. corrects the masked image signal, and a PWM 36 performs pulse-width modulation on the .gamma.-corrected image signal. Image output is made by driving a semiconductor laser 120 with the pulse-width modulated signal.

摘要： In a raster scanning system (ROS) of a multi-station xerographic printing device, the image height of each of the images formed from a plurality of clustered laser beams having dissimilar wavelengths is changed so that the image heights approximate each other. This is accomplished by passing one or more of the light beams through light transmissive plates having a predetermined thickness and index of refraction. The light transmissive plates can be optical filters that also one used to separate the clustered light beams based upon their wavelength and/or polarization.

摘要： A single pass highlight color printer is disclosed which utilizes two pairs of Raster Output Scan (ROS) systems mounted symmetrically about a common polygon motor assembly. Four identical optical systems are thus provided, 180.degree. apart with diode laser outputs directed from a ROS frame parallel and separated to allow the appropriate spacing for xerographic components situated adjacent the xerographic belt. Each ROS unit includes a 90.degree. mirror pair which is mounted on a roof mirror carriage which in turn is connected to a focus carriage via an adjustable guide system. The interaction between the focus carriage and the roof mirror carriage enables a skew alignment and process (beam steering) adjustment to be accomplished with a high degree of precision.
