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 |

20100226702 | Hard Image Forming Apparatuses and Methods - Hard image forming apparatuses and methods are described. According to one arrangement, a hard image forming apparatus includes an imaging member comprising a surface, a development system configured to provide a marking agent to the surface of the imaging member to form developed images upon the surface of the imaging member which correspond to latent images formed using the surface of the imaging member, and a transfer system configured to transfer the developed images from the surface of the imaging member to media. The arrangement further includes a contamination removal device configured to remove contamination material from the surface of the imaging member, and a control system configured to control the contamination removal device to contact the surface of the imaging member to remove the contamination material from the surface of the imaging member at a first moment in time and to space the contamination removal device from the surface of the imaging member at a second moment in time where the contamination removal device does not remove the contamination material from the surface of the imaging member. | 09-09-2010 |
20110200363 | CONDUCTIVITY SENSOR WITH CLEANING APPARATUS - A system and method for determining LEP ink conductivity are provided. A pair of electrodes is arranged to define a narrow gap there between. A non-conductive propeller rotates within the gap and causes liquid ink to flow over respective planar surfaces of the electrodes. The rotating propeller further prevents the accumulation of ink sludge on the planar surfaces of the electrodes within the gap. Electrical current is conducted between the electrodes. The electrical current is measured and the conductivity value of the ink determined there from. | 08-18-2011 |

20090097883 | Liquid electro-photography printing device binary ink developer having suction cavities - A binary ink developer (BID) for a liquid electro-photography (LEP) printing device includes a sponge roller to absorb unused ink. The BID includes a squeezer roller to release the unused ink absorbed by the sponge roller for reuse. The squeezer roller releases the unused ink absorbed by the sponge roller by compressing the sponge roller. Compression of the sponge roller results in ink foam. The BID includes a mechanism having a wall, and a housing that together with the wall of the mechanism defines a passageway between the housing and the wall. The passageway is exposed externally to the BID. The BID includes one or more suction cavities defined within the wall of the mechanism through which the ink foam moves back from the passageway. | 04-16-2009 |

20120320378 | Optical Density Sensor Calibration and Self Fixing - A method of calibrating an optical density sensor comprising calculating a first pigment solid density value of an ink solution using a current first electrical output signal value from a photodetector, a current second electrical output signal value from a photodetector, and a current lens gap value, calculating a second pigment solid density value of the ink solution using a previously measured first electrical output signal value, a previously measured second electrical output signal value, and a previously measured lens gap value, comparing the current first electrical output signal value, the current second electrical output signal value, and the current lens gap value with the previously measured first electrical output signal value, the previously measure second electrical output signal value, and the previously measured lens gap value, and comparing the first pigment solid density value with the second pigment solid density value. | 12-20-2012 |
20130229657 | DENSITOMETER FOR MEASURING AN OPTICAL CHARACTERISTIC OF A FLUID - A device and method for measuring an optical characteristic of a fluid. The device, typically a densitometer includes a set of optical elements that include a light source, a collimating lens, a focusing lens, and a receiver, wherein a gap exists between the collimating lens and the focusing lens so as to allow the fluid to pass in between the lenses, and wherein at least one of the optical elements is tilted with respect to an optical axis. | 09-05-2013 |
20130235380 | CALCULATING THE CONCENTRATION OF SOLIDS IN A FLUID - A system and method to calculate a concentration of solids in a fluid, the system including a light source to generate a light signal of predefined characteristics, a an optical detector, placed opposite the light source across a gap between the light source and the detector through which the fluid may flow and a processor to identify the light signal in a detection signal generated by the optical detector, and to calculate the concentration of solids in the fluid based on the identified light signal as related to the generated light signal. | 09-12-2013 |
20140375997 | CALCULATING THE OPTICAL DENSITY OF A FLUID TRAVELING THROUGH A GAP - A method and apparatus to calculate the optical density of a fluid ( | 12-25-2014 |
