Abstract: A print press system and a method are described herein that print an electronic circuit onto a material (e.g., glass substrate, plastic film, plastic film-glass substrate laminate). In exemplary applications, the print press system can print an electronic circuit onto a material to form, for instance, a flexible Liquid Crystal Display, a retail point of purchase sign and an e-book.

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: An inkjet printing apparatus which performs time-divisional driving poses the following problem for at least some gray levels when halftoning control by the unit matrix is performed. More specifically, the shape of a dot cluster in each unit matrix periodically changes due to the mismatch between the unit matrix size and the unit section size of time-divisional driving. For this reason, periodical density unevenness is generated and appears as degradation of the image quality. In order to prevent degradation of the image quality, according to this invention, image data is shifted in accordance with the unit section of time-divisional driving, or the discharge timing of ink from a printhead is shifted.

Abstract: After having been reflected by a first return mirror, a light beam deflected by a polygon mirror is caused to travel toward a second return mirror disposed in a position below a base section of the polygon mirror by way of an opening. An image forming apparatus is configured so as to satisfy a relationship of a<b and another relationship of c<b, given that an optical path length from a reflection surface of the polygon mirror to a reflection surface of the first return mirror is taken as “a”; another optical path length from the reflection surface of the first return mirror to a reflection surface of the second return mirror is taken as “b”; and still another optical path length from the reflection surface of the second return mirror to the surface of the photosensitive member is taken as “c.

Abstract: Gray scale printing data with compensation for dispersion is stored in a first shift register, the data is sliced into respective bits and is fetched by means of a second shift register and AND-gates. Standard resistances are scanned by means of a third shift register and switches, in synchronization with the data retrieval, for changing standard current, and light emitting current to light emitting bodies is changed according to the standard current.

Abstract: Odd- and even-numbered conductors of recording electrodes, for example, first or second recording electrodes, are divided in the direction in which the conductor at the time of winding are stacked up to form different layers so as to increase the distance between the conductors of the adjoining recording electrodes and reduce the floating electrostatic capacitance.

Abstract: A toner projection printer is provided with a developer surface which manifests a developer bias, and includes a cloud of entrained toner particles. A platen is positioned opposed to the developer surface and manifests a platen voltage that is attractive to the toner particles. An address plate is positioned between the developer surface and the conductive platen. The address plate includes a determined thickness insulator with through pixel apertures. Each pixel aperture has at least a first conductive electrode ring positioned within the insulator and connected to a drive plate that is also positioned within the insulator. A first drive circuit positioned on one side of the insulator and is capacitively coupled to the drive plate for controllably applying a row drive voltage thereto. A second drive circuit is positioned on a second side of the insulator and is capacitively coupled to the drive plate for controllably applying a column voltage drive thereto).

Abstract: An electrostatic recording head used for forming an electrostatic latent image of an image to be recorded on a recording medium comprises a plurality of electrode groups, each group including a plurality of needle-like electrodes. The needle-like electrodes of all the groups are arranged linearly in at least one line. A plurality of auxiliary electrodes are disposed such that each of the electrode groups faces at least one of the auxiliary electrodes. An auxiliary electrode driving unit drives the auxiliary electrodes independently of each other. Each of the electrode groups is divided into a plurality of subgroups, each subgroup including at least one of the needle-like electrodes. A subgroup driving unit is provided for each of the subgroups for driving the subgroups independently of each other.

To execute a scanning of the LED array chip emitting in response to drive signals from said drive IC by scanning means to provide repetitious m-divisional scans for each n-partitioned group of chips simultaneously, a control device controls each drive IC, upon leaving a scan in a finest group of chips, to start scanning LED array chips in an adjacent succeeding group with respect to the scanning direction, while another drive IC starts scanning in the first group of chips, the array and the driver thereby scanning in waves to achieve faster printing speed with reduced electronic consumption.
