Abstract: An image processing apparatus includes an input unit for inputting coded data from an external apparatus. A developing unit develops the coded data into bit map data, an output unit outputs the bit map data to a printing unit, and a unit predicts a time needed for developing coded data for one page into bit map data. The predicting unit transmits a timing signal for starting preparatory operations by the printing unit with a timing based on the predicted time.

Abstract: A color image recording apparatus comprises edge detection device with image sensors for detecting longitudinal edges of electrostatic recording paper, and mark detection device for detecting registration marks formed at an equal pitch along the edges of the recording paper. Both edges are detected at a first pass thereof through the edge detection device, and the detected output is stored in a memory. During each of second and subsequent passes, detected data is compared with the initially stored data to correct for expansion and shrinkage of the recording paper. Oblique motion of the recording paper is detected from the timing difference between registration marks formed on opposite sides of the recording paper, which timing difference is used to change line recording timing. A single correction is periodically repeated and changed until completion of the correcting for oblique motion of the recording paper as well as expansion or shrinkage thereof, hence ensuring an exact positional coincidence of the individual color images.

Abstract: An improved method and apparatus for grey level printing using linear arrays of LED's or the like are described. In one embodiment, a circuit is provided that includes a look-up table that compares for each pixel to be printed a time-changing count from a threshold counter with a multibit signal representing a grey level value. In accordance with the program in the look-up table, a two-bit signal is fed to the printhead and used to turn the LED on at an intensity level commensurate with the two-bit signal. This process is repeated many times to determine the "on" time or pulsewidth of the LED for that pixel. With each repetition, a new two-bit signal is generated to define intensity level. In another embodiment, the number of repetitions of this process are shown to be substantially reducible by using a vernier clocking scheme involving a clock signal having different frequencies.

Abstract: A print engine including a two-dimensional matrix print head is operated by data signals from a raster image processor through a distributed digital controller having a master controller and a plurality of separate controllers each for a separate set of elements along one of the dimensions of the array, specifically the finger control electrodes of an ion projection printing head. The elements along the other dimension of the array (the RF electrodes of the ion projection head) are controlled by the master controller which also controls the timing of writing of the pixel data signals into memories associated with each of the distributed controllers and the timing of the readout of the pixel data to the finger control electrodes in synchronism with the activation of the RF electrodes and the movement of a medium on which the image is printed so as to print portions of each line in sequence (interleaving dots representing pixels on each line) to form the image on the medium. The pixel data is in the form of digital grey-scale data words representing the grey scale or density of the pixels. The distributed controllers have counters which are preset by the grey-scale data words and deliver pulses of duration (a pulse width modulated output) which varies the density or grey scale of the dots.

Abstract: An optical printer head using LEDs, which is a form of image forming apparatus, comprises a plurality of arrays formed from a plurality of LEDs arranged in a straight line, the LEDs disposed symmetrically to each other in adjacent arrays being connected to respective individual signal lines formed in a cranked pattern extending from one array to the next, to supply printing data. Because the arranging order of the LEDs relative to the individual signal lines is reversed between adjacent arrays, prior art has required the provision of an external circuit for alternately reversing the arranging order of image data from one array to the next. On the other hand, according to the present invention, the optical printer head contains a hardware circuit configuration for reversing the arranging order of the input image data each time a signal generated for each array is supplied. As a result, the image data to be input to the optical printer head should only be supplied in accordance with the arranging order of the LEDs, and the arranging order of the thus input image data is changed accordingly in real time to drive the LEDs in the corresponding array. This serves to achieve the high speed driving of the optical printer head and the simplification of the circuit configuration.
