20090080939 | Apparatus for containing splashes in an ink developer - A splash guard is configured to control the flow of excess liquid generated by an interaction between a first roller and a second roller by splitting the flow of the excess liquid into a first flow and a second flow. | 03-26-2009 |
20110074894 | Reducing Ink Droplets Generated By Bursting Bubbles In An Ink Developer - An apparatus for reducing ink droplets generated by bursting bubbles within an ink developer includes a surface directing an ink flow into a channel; and a protrusion within the channel that reduces ink droplets generated by bursting bubbles entrained within the ink flow. An ink developer includes an ink source supplying ink to the ink developer; an electrode which develops a portion of the ink onto a developer roller; and a splash guard which directs an undeveloped ink flow into a channel which has a reduced cross-section area configured to reduce bubbles exiting the channel and bursting. | 03-31-2011 |
20120148310 | LIQUID MARKING AGENT DEVELOPMENT ASSEMBLIES, HARD IMAGING DEVICES, AND LIQUID MARKING AGENT HARD IMAGING METHODS - Liquid marking agent development assemblies, hard imaging devices, and liquid marking agent hard imaging methods are described. According to one aspect, a liquid marking agent development assembly includes a developer member comprising an outer surface, a marking agent delivery system configured to supply a liquid marking agent comprising a plurality of ink particles to a first location of the outer surface of the developer member, and a development system configured to adhere a plurality of the ink particles to the outer surface of the developer member, and wherein the development system is configured to adhere at least a majority of the adhered ink particles at a second location of the outer surface of the developer member which is upstream from the first location with respect to a direction of movement of the outer surface of the developer member. | 06-14-2012 |
20120148311 | LIQUID MARKING AGENT DEVELOPMENT ASSEMBLIES AND LIQUID MARKING AGENT HARD IMAGING METHODS - Liquid marking agent development assemblies and liquid marking agent hard imaging methods are described. According to one aspect, a liquid marking agent development assembly includes a developer member comprising an outer surface and a charging assembly adjacent to the outer surface of the developer member, and wherein the charging assembly comprises at least one roller member configured to provide substantially an entirety of an electrical field relative to the developer member which electrical field is used to direct a plurality of ink particles of a liquid marking agent to the outer surface of the developer member and which ink particles upon the outer surface of the developer member are used to develop latent images upon an imaging member. | 06-14-2012 |
20130149002 | INK DEVELOPER UNIT, AND SEALING DEVICE USABLE WITH INK DEVELOPER UNIT - A sealing device includes a base member configured to attach to an ink developer unit, a sealing member having a sealing surface configured to at least one of limit an unwanted flow of ink outside of the ink developer unit and conform to an outer surface of a respective roller, and a compliant member disposed between the base member and the sealing member such that the compliant member is configured to vary a sealing force along the sealing surface of the sealing member. | 06-13-2013 |
20130223888 | APPARATUS TO RECEIVE A DEVELOPER ROLLER - An apparatus to receive a developer roller for a printing device. The apparatus comprises a base assembly including end caps at opposing ends. The base assembly includes a receptacle for a developer roller having rotary bearings. Each end cap includes first and second datum pins and a clamp containing a spring member. Each clamp, when locked in place in part by action of the spring member, is to push against a corresponding rotary bearing when the developer roller is installed in the base assembly. The rotary bearing being forced by the clamp into contact with the first and second datum pins to position the developer roller in the base assembly. | 08-29-2013 |
20140029971 | SEALING DEVICE INCLUDING A FIRST REPLACEABLE COMPLIANT SEALING MEMBER AND A LATCH MEMBER - A sealing device usable with an ink developer unit including a plurality of rollers and a plurality of end cap members includes a first replaceable compliant sealing member and a latch member. The first replaceable compliant sealing member has a plurality of replaceable seal exterior surfaces to form a seal between a first set of rollers of the plurality of rollers and one of the end cap members. The latch member has a closed state to maintain a sealing force on the first replaceable compliant sealing member and an open state to remove the sealing force on the first replaceable complaint sealing member. | 01-30-2014 |
20140348526 | DETERMINING THE CONDUCTIVITY OF A LIQUID - In one example, a processor readable medium has instructions thereon that, when executed by a processor, cause a system to detect a change in electrical conduction of a liquid moving at an interface between two surfaces and determine a conductivity of the liquid based on the detected change in conduction. | 11-27-2014 |
