| 20090047587 | ELECTROPHOTOGRAPHY DEVICE - Embodiments of an electrophotography device are disclosed. | 02-19-2009 |
| 20090128616 | APPARATUS AND METHOD OF REDUCING BANDING ARTIFACT VISIBILITY IN A SCANNING APPARATUS - A method of, and apparatus for, reducing the visibility of banding artifacts on a printed medium comprising producing synthetic artifacts on the printed medium, overlapping scan lines at swath boundaries and controlling exposure along a scan line to reduce the visibility of the banding artifacts. | 05-21-2009 |
| 20100003045 | ELECTROGRAPHIC DOT GAIN AND OPTICAL DENSITY DECOUPLING METHOD, XEROGRAPHIC IMAGE REPRODUCTION, AND SYSTEMS, METHODS AND SOFTWARE RELATED THERETO - A method is provided for decoupling the control of dot gain and optical density in electrophotographic based printing by varying the exposure level for each dot in an image. | 01-07-2010 |
| 20100251916 | CLEANING STATION - A cleaning station includes a fluid input which introduces a passive flow of fluid into a trough and a slit which provides an outlet through which the fluid exits the trough. A wetting roller rotates in a cylindrical cavity to form a viscous fluid pump which draws the fluid through the slit to form a fluid film on an outer surface of the wetting roller. | 10-07-2010 |
| 20100296825 | DEVELOPMENT MONITORING METHOD AND SYSTEM - A method for monitoring development parameters of a liquid toner electrophotographic (LEP) printer, the method comprising defining an operational window for a current utilized by the printer and monitoring the current to determine a deviation of the current outside the operational window. | 11-25-2010 |
| 20110058837 | DETECTING COLORANTS WITHIN CARRIER LIQUID - A detecting apparatus is to at least assist in determining the concentration of colorants within a carrier liquid. The colorants at least absorb light and/or diverge light. The detecting apparatus includes one or more light sources to emit light, and one or more light detectors to detect light. The light sources and the light detectors are positionally configured in relation to one another such that both light directly emitted by the light sources and that has not been absorbed or diverged by the colorants, as well as light diverged by the colorants within the carrier liquid, are detected and/or determined. The concentration of colorants is determined based on the light directly emitted by the light sources that has not been absorbed or diverged by the colorants and/or on the light diverged by the colorants within the carrier liquid. | 03-10-2011 |
