Abstract: A binary ink developer (BID) may include a power supply electrically coupled to an electrode, a developer roller, and a cleaner roller. The BID may also include a controller to determine a level of image ghosting based on a sum of currents at the electrode, the developer roller and the cleaner roller, and instruct the power supply to provide an adjusted voltage to the cleaner roller in response to a determination of the level of image ghosting.

Abstract: An example developer unit includes a developer roller. The developer unit also includes a set of electrodes proximate to the developer roller. The set of electrodes form a cavity. The developer unit includes an inlet to the cavity. The inlet is to receive printing fluid. The developer unit includes an insert in the inlet. The insert is to distribute the printing fluid evenly in the cavity.

Abstract: 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.
Abstract translation: 在一个示例中，处理器可读介质在其上具有指令，当由处理器执行时，该指令使得系统检测在两个表面之间的界面处移动的液体的电传导变化，并且基于检测到的液体确定导电性 传导变化。

Abstract: In one embodiment, a printer includes a device configured to form a semisolid toner film on a print substrate and a fixer configured to, without contacting the toner film, soften the toner film on the print substrate until polymers in the toner are mobile enough to allow polymer functional groups to bond with the print substrate.
Abstract translation: 在一个实施例中，打印机包括被配置为在打印基板上形成半固体调色剂膜的装置，以及定影器，其被配置为在不接触调色剂膜的情况下软化印刷基板上的调色剂膜，直到调色剂中的聚合物足够移动以允许 聚合物官能团与印刷基底结合。
