摘要： In an ink jet printer, it is desirable to compensate the flight of the ink drops to correct for print errors caused by aerodynamic effects. The apparatus shown herein corrects the flight of ink drops for all aerodynamic effects, drop interactive and environmental. Correction for drop interactive effects can be accomplished in any of several well known ways. The additional correction for environmental effects is accomplished by scaling the drop interactive correction. The scale factor is first determined for static environmental conditions. Environmental conditions include the climate in which the printer operates and the specifications on the component parts of the ink jet printing assembly. The scale factor can be adjusted dynamically for changes in the environment. In particular, changes in air density of the environment are monitored and used to dynamically adjust the scale factor.

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： The ink jet head assembly disclosed herein has modular subassemblies with predetermined relationships between the subassemblies to minimize realignment of the ink stream when a subassembly is replaced in the field. The head assembly is modularized into nozzle, charge electrode, deflection electrode and gutter subassemblies. The charge electrode module is mounted on the nozzle module in a manner such that no field adjustment is necessary to center the charge electrode horizontally to the ink stream. The deflection electrode module is mounted on the gutter module in a manner such that no field adjustment is necessary to center the deflection electrode horizontally to the ink stream. The nozzle and charge electrode subassembly have a preset adjustment, and the gutter and deflection electrode assembly have a preset adjustment such that no field adjustment between these two subassemblies is necessary to maintain a constant flight distance for the ink drops. Finally, the nozzle module is adjustable to reposition the ink stream about the pitch axis (vertical adjustment) and the yaw axis (horizontal adjustment). The yaw axis adjustment may be preset. The pitch axis adjustment is the only mechanical adjustment necessary in the field when replacing the nozzle module.
摘要翻译：本文公开的喷墨头组件具有在子组件之间具有预定关系的模块化子组件，以在子组件在现场更换时最小化油墨流的重新对准。头组件模块化成喷嘴，充电电极，偏转电极和沟槽子组件。充电电极模块以这样的方式安装在喷嘴模块上，使得不需要场调整来使充电电极水平地对准墨水流。偏转电极模块以这样的方式安装在沟槽模块上，使得不需要场偏转来使偏转电极水平地对准墨水流。喷嘴和充电电极子组件具有预设的调整，并且沟槽和偏转电极组件具有预设的调整，使得这两个子组件之间不需要进行现场调整以保持墨滴的恒定的飞行距离。最后，喷嘴模块是可调节的，以便绕着俯仰轴线（垂直调节）和偏转轴线（水平调节）重新定位油墨流。可以预设偏航轴调整。在更换喷嘴模块时，俯仰轴调节是现场唯一必要的机械调节。
