The first light emitting element row includes the arrangement of first light emitting elements. The second light emitting element row includes second light emitting elements arranged in parallel with the first light emitting element row. The lens array concentrates light emitted by the first light emitting elements and the second light emitting elements. The first drive circuit drives each first light emitting element with an identical first current value. The second drive circuit drives each second light emitting element with an identical second current value different from the first current value.

摘要： Systems and methods for printing data on a substrate including a color-changeable material are provided. One system includes a processing circuit and a device including an energy source. At least a portion of a printed publication is printed on the substrate using a commercial printing press based on fixed data. The device including the energy source is configured to add variable data to the substrate. The processing circuit is configured to receive the variable data and to control the energy source to change a color of the color-changeable material based on the variable data to provide at least a portion of the printed publication. The processing circuit is configured to control the energy source to change the color of the color-changeable material in-line with a flow of the substrate through one of a printing line, a finishing line, or a packaging line of the commercial printing press.

摘要： Electrophotographic (EP) streaking compensation is performed. A tonescale is measured for each column and a per-column gain computed to compensate for variations. An adjustment tonescale is determined and a per-column adjustment-tonescale gain computed to correct for remaining error after the per-column gain is applied. The two corrections are used together to provide improved compensation quality.

摘要： In a line head, a plurality of element arrays arranged in a first direction. Each array includes a plurality of light emission elements arrayed in a second direction which is perpendicularly to the first direction. The light emission elements emit light for forming an electrostatic latent image on a photosensitive surface of an image carrier. A switcher activates the light emission elements in at least one of the element arrays while deactivating the others. A developer develops the latent image as a visible image with toner.
