    Abstract: A recording head for use in an electrostatic printer comprises four staggered rows of styli. Signals for driving each row of styli are transmitted through a buffer wherein the signals for the first row of styli are transmitted without delay to the styli, the signals for the second row of styli are transmitted with an appropriate delay of a first selected time, the signals for the third row of styli are transmitted with an appropriate delay of a second selected time and the signals for the fourth row of styli are transmitted with an appropriate delay of a third selected time. The delay means comprises a random access memory driven by address counters controlled by a control sequencer to function as a delay. The four staggered rows of styli are formed by a novel method wherein the styli in the second row are formed between the styli in the first row and the stylis in the third and fourth rows are formed by making use of the grooves formed between the styli in the first and second rows. By forming the rows of styli on a cylindrical drum, two recording heads are obtained from each fabrication run wherein the recording head in one set of styli is the mirror image of the recording head in the other set of styli. Should an error occur in the manufacture of the styli by placing the third row of styli in the grooves where the fourth row of styli normally belongs, the resulting recording heads are identical to those obtained with the proper placement of the third and fourth rows with the exception that the position on the drum of each type of recording head is reversed.

    Abstract: A diode switching system for use with an electrographic writing system is disclosed. The switching system has a high storage charge diode with a capacitor connected to its anode which defines an output. Once the diode is charged, application of a large drive voltage to the free end of the capacitor will short the voltage through the diode due to the stored charge of the diode, thus preventing the stylus from writing. When the diode has not been charged, application of a large drive voltage will be coupled through the capacitor thus powering the writing stylus.

    Abstract: A large number of printing electrodes are combined to form groups which each time have a common switching point, each printing electrode of the same ordinal number of each group being connected to a common voltage amplifier. A capacitor (C) is connected between the common switching point (G) of a group and the electrical control element (SK) associated with each printing electrode (BE). All capacitors are simultaneously charged, however, consecutively one group after the other, to the analog voltages which correspond to the information to be printed and which are present on the relevant voltage amplifiers (V). The time required for the charging of all capacitors (C) is less than the printing time for an image element. The circuit arrangement is particularly suitable for an electrophoretic printing method.

    Abstract: Electrographic recording heads are fabricated using printed circuit techniques. A head with two parallel rows of recording electrode areas is constructed by forming two confronting rows of electrode conductors on one face of a thin substrate. The substrate then is folded and secured together substrate-tosubstrate so that there is a row of conductors on each face of the folded structure. The structure then is severed across the conductors adjacent to the fold, exposing a cross sectional area of each conductor thus establishing two rows of recording electrode areas, with the rows separated by the thickness of two layers of substrate material. A head with a single row of closely spaced electrode areas is constructed in similar fashion except that the substrate is folded conductors-toward-conductors. The conductors of the two rows are dimensioned and located so that the conductors of one row interleave between the conductors of the other row. Thus, when the portion adjacent to the fold is severed, there is exposed a single row of recording electrode areas which may have very close spacing. Prior to folding the substrate, selected electrode conductors are interconnected by printed circuit techniques. Front shoe complementary electrodes are formed on separate substrate.

    Abstract: A device including: a photoreceptor; an LED printbar; and a computer processor for: determining how long LEDs on the printbar are energized while the device is operated to generate an image output; determining that a first plurality of LEDs has been energized less than a second plurality of LEDs; energizing the first plurality of LEDs for a correction time period as the LEDs are aligned with an inter-document zone (IDZ); and de-energizing the second plurality of LEDs during the time period. Energizing the second plurality of LEDs is unrelated to energizing the LEDs for purposes of evaluating an image. The time period is concurrent with operation of the device to generate an image output.

    Abstract: Differing ratios of the amount of light from light source LD2 to the amount of light from light source LD1 are provided. An image pattern for adjustment that includes, for each color, an area made up of isolated dots by light source LD1 and an area made up of isolated dots by light source LD2, is printed for each ratio. In a copier, a density of each area is detected, a ratio at which a difference between the density of an area of isolated dots by light source LD1 and the density of an area of isolated dots by light source LD2 is smallest is decided as an adjustment ratio, and control is performed such that light sources LD1 and LD2 emit light at the adjusted ratio.

    Abstract: An image forming apparatus and an image forming method in which a latent image is formed by scanning the surface of an image bearing body with a laser light blinking in accordance with pulse-width modulation based on an image signal. Output-control-wave generating device generates an output control wave having a peak for a write time of each picture element. The output control wave is turned on and off by a gate circuit with timing determined by an exposure control signal generated by exposure control device. A signal output by the gate circuit is converted by a V/I converter into a driving current wave for controlling radiation of a laser light by an exposure unit. In this way, exposure energy produced by the exposure unit can be concentrated on an exposure time duration of each picture element, allowing the amount of mutual interference among picture elements to be reduced.
