  • Publication number: 20110181579
    Abstract: A driving apparatus includes a voltage applying unit, a light irradiation unit and a resistance control unit. The voltage applying unit forms a voltage applying circuit together with a pair of electrode layers of a photo-addressing type display element. The voltage applying unit applies a voltage between the pair of electrode layers. The light irradiation unit irradiates the photo-addressing type display element with addressing light. The resistance control unit controls a resistance to a current which flows in a direction to reduce a potential difference between the pair of electrode layers to be larger than that during a period in which the voltage applying unit is applying the voltage.

  • Publication number: 20110182506
    Abstract: A color processing apparatus includes a memory, a color-difference-accuracy calculating unit, an invertibility-accuracy calculating unit, and an output unit. The memory stores a patch set including patch colors. The color-difference-accuracy calculating unit calculates, as a color-difference accuracy, a color difference between a measured color value, which corresponds to a target color, and a predicted value, which is predicted from the target color using a color conversion model generated from the patch set and measured color values corresponding to the patch colors. The invertibility-accuracy calculating unit calculates, as an invertibility accuracy, a difference between the target color and a predicted target color that is predicted from the predicted value using a model with which transformation is performed in a direction opposite to a direction of transformation using the color conversion model. The output unit outputs the color-difference accuracy and the invertibility accuracy.

  • Publication number: 20110180526
    Abstract: An airflow system for a solid-ink melter tank is disclosed, which prevents clogging of drop tube supplying solid ink to the solid-ink melter tank. An inlet may provide airflow as well as solid ink to the melter tank and an outlet maintained at a temperature higher than temperature of the inlet, promotes a convective air current. The inlet may be coaxial with the drop tube or is present as a separate opening in the solid-ink melter tank. The outlet can be taller, externally insulated, and fabricated with a thermally conductive material as compared to the inlet. The heated outlet promotes expulsion of hot air from the solid-ink melter tank and prevents heating of drop tube, which leads to drop tube clogging by partially melting the solid ink.

  • Publication number: 20110181647
    Abstract: A method uses temperature measurements for a print head and an imaging member to identify a distance between a print head and an imaging member. The method determines whether the print head at the print position is too close to the imaging member to identify the gap distance without damage to the print head. Then, if the print head is not too close, the print head is heated to quantify the heat sink effect of the imaging member on the print head. This effect is related to a heat transfer function that identifies the gap distance between the imaging member and the print head.

  • Publication number: 20110183241
    Abstract: Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising a protective outer layer which comprises light-absorbing composition that substantially prevents any light absorption by the overcoat layer. The composition comprises a low strength thermal plastic resin and a high optical density yellow dye. Thus, the light-blocking protective layer reduces the intrinsic light shock suffered by conventional overcoat layers without negatively impacting electrical properties of the overcoat layer and while improving print quality.
