摘要： Embodiments described herein provide ink recirculation capabilities for Drop-On-Demand (DOD) printing systems. One embodiment comprises a system that includes a controller, a DOD print head, an ink tank, an ink pump, and a recirculation cap. The ink pump transports ink from the ink tank to the DOD print head, and the recirculation cap captures ink ejected by the DOD print head. The recirculation cap also transports the capture ink to the ink tank. In response to detecting a start of an ink recirculation cycle, the controller collocates the recirculation cap proximate to nozzles of the DOD print head, and directs the DOD print head to begin ejecting ink through the nozzles into the recirculation cap for transport of the captured ink to the ink tank. The controller detects an end to the ink recirculation cycle, and directs the DOD print head to stop ejecting ink into the recirculation cap.

摘要： An ink jet pump is switched from a mechanically off or idle state to a mechanically on or active state with no drift in pressure output by maintaining the pump at the same point in its force-temperature characteristic when it is on and off. This is accomplished by driving the pump in both the active and idle states with signals that dissipate the same amount of power in the pump. The frequency of the idle state signal is high enough that the pump can not mechanically respond. The power dissipations in the active and idle states are matched by adjusting the current build-up and current decay through the coil of the pump during the idle state. When the RMS current through the coil in the active state equals the RMS current in the idle state, the power dissipations are matched.

摘要翻译： 当喷射泵打开和关闭时，通过将泵保持在其强度 - 温度特性的相同点，将喷墨泵从机械关闭或空闲状态切换到机械打开或活动状态，而不会在压力输出中发生漂移。 这是通过在主动和空闲状态下驱动泵来实现的，该信号在泵中消耗相同的功率量。 空闲状态信号的频率足够高，使得泵不能机械响应。 在空闲状态期间，通过调节电流通过泵的线圈的电流积分和电流衰减来调节有功和空闲状态下的功率消耗。 当通过有源状态的线圈的RMS电流等于空闲状态下的RMS电流时，功率耗散被匹配。

摘要： Fire control and containment for a production printing system that includes a dryer unit, an air intake fan, and an exhaust fan. A fire control and containment system includes an enclosure surrounding the dryer unit. The enclosure includes controllable doors, a temperature sensor, and an air pressure sensor in the enclosure. The fire containment and control system also includes a controller operable to detect a fire event based on changes in air pressure and air temperature in the enclosure detected by the air pressure and air temperature sensors. In response to detecting the fire event, the controller closes the doors of the enclosure to prevent the print medium from entering, controls the air intake fan and the exhaust fan to reduce the air pressure in the enclosure, and controls the dryer unit to reduce temperature in the enclosure to suppress fire.

摘要： An printer, such as a state of the art a high performance, electro-photographic printer. The printer includes at least one smart material sensor enclosed in the printer enclosure that monitors for the presence of a contaminant (e.g., toner or developer) above a selected threshold. Each smart material sensor is coupled to a control unit by a sensor driver coupling. When a smart material sensor finds that a contaminant is present the control unit may indicate the finding on a printer display and/or change operating mode.
