摘要： A substrate for a recording head includes a circuit through which current flows upon impression of a source voltage, irrespective of the operating state of an energy converting element, and a current cutoff means for cutting off current to the circuit in response to an entered control signal. A reset signal for achieving a standby state of the printing operation serves as the control signal. The current cutoff circuit is operated when the reset signal is active in an H state, and it cuts off the constant current. By cutting off the constant current, the leak current of a heater power source VH may be accurately measured, permitting determination of whether the source voltage wiring is properly insulated from other circuit elements of the substrate. The constant current may also be cut off in the standby state, in which printing is not performed, so as to reduce power consumption.
摘要翻译：用于记录头的基片包括电流，不管能量转换元件的工作状态如何，通过电流流过电源电压，以及电流切断装置，用于响应输入的控制信号切断电路电流。用于实现打印操作的待机状态的复位信号用作控制信号。当复位信号处于H状态时，电流截止电路工作，并切断恒流。通过切断恒定电流，可以精确地测量加热器电源VH的泄漏电流，从而可以确定源极电压布线是否适当地与衬底的其它电路元件绝缘。在不进行打印的待机状态下也可以切断恒定电流，以便降低功耗。

摘要： An ink protection device for an inkjet printhead comprises a flap member associated with the printhead and extending generally parallel to the ink ejection surface of the printhead so that when the printhead is mounted in the carriage the flap member extends between the carriage and a face of the printhead, particularly the electrical interconnect face. The device may be in a two part laminar form attached to the bottom of a carriage of the printer and having a flexible part for contacting all four faces of the printheads and a stiff part for support. Both parts having openings aligned with the openings in the carriage through which the printhead snout passes.
摘要翻译：用于喷墨打印头的油墨保护装置包括与打印头相关联并且大致平行于打印头的喷墨表面延伸的挡片部件，使得当打印头安装在滑架中时，挡板部件在滑架和面板之间延伸打印头，特别是电互连面。该装置可以是连接到打印机的托架的底部的两部分层状形式，并且具有用于接触打印头的所有四个面的柔性部分和用于支撑的刚性部分。两个部件具有与打印头喷嘴穿过的滑架中的开口对齐的开口。
