  • Patent number: 8023127
    Abstract: An image processing apparatus includes a background image generation section and a combining section. The background image generation section generates a background image, which represents (i) background information containing copy prohibition information indicating copy is prohibited and (ii) copy prohibition release information indicating a condition to release copy prohibition, by predetermined patterns. The combining section combines a target image to be formed and the background image generated by the background image generation section to generate a composite image and that outputs the composite image to a formation section that forms an image on a recording medium. When generating the background image, the background image generation section arranges the pattern of the copy prohibition release information in an end region of the recording medium.

  • Patent number: 8023539
    Abstract: Provided is a method for driving a surface emitting semiconductor laser including an active region that generates light, a resonator structure disposed such that it sandwiches the active region, and a driving electrode that provides power to the active region. The surface emitting semiconductor laser has an internal resistance defined by voltage and current applied to the driving electrode. The method includes applying a modulation signal to the driving electrode, in which the modulation signal has a current amplitude defined by a first current value and a second current value that is greater than the first current value. The modulation signal is in a negative gradient region in which the internal resistance decreases in contrast to the increase of the current.

  • Patent number: 8020865
    Abstract: A novel media path mechanism which utilizes the position and/or motion of buffer nips to deflect the leading and trailing edges of the sheets entering the buffer to enable the sheets to be reliably shingled in the buffer media path. The sheets are stored in properly collated order until needed for insertion into the print stream. By shingling or overlapping successive sheets in close relationship in a row within the buffer, this process can greatly increase the volume of storage or parking of sheets within the buffer. This can significantly reduce the size or footprint of the buffer within the printing system or significantly increase the capacity of an existing system.
