摘要： An intrusion of air (22) into the ink chambers (24) of a printhead substrate (50) is a symptom of either a depleted ink supply (26) or a deprimed printhead substrate (50). When the printer (20) attempts to print with a depleted ink supply (30) or a deprimed printhead substrate (50), the printhead substrate (50) must absorb all of the energy dissipated in the ink chambers (24) to eject the drops. This causes the printhead substrate (50) to reach high temperatures. The present invention detects a depleted ink supply (26) and a deprimed printhead (50) by monitoring the temperature of the printhead substrate (50) and comparing this temperature with a threshold (84, 90, 96). When this temperature exceeds the threshold (84, 90, 96) for more than an allotted amount of time, then corrective action is taken.
摘要翻译：基板到空气（22）的侵入的打印头（50）的墨室（24）可以是一个耗尽的墨源（26）或一个打印头deprimed基板（50）的症状。当打印机（20）尝试与耗尽的墨源（30）或一个deprimed打印头基板（50）进行打印，所述打印头基板（50）必须吸收所有在墨室消散（24）的能量的喷射的液滴，这使得打印头基片（50），以达到高的温度。本发明检测通过监测打印头基板的温度（50）和该温度与阈值（84，90，96）进行比较的耗尽墨源（26）和打印头deprimed（50）。当该温度超过比的时间分配量多的阈值（84，90，96），则采取校正动作。

摘要： An on-demand type ink jet print head is described, comprising: a plurality of ink tanks (3,4) disposed at a lower position of a carriage to be independent of each other, pressure varying means provided on one of the tanks (3,4); an air release port (11) communicating with the other one of the tanks (3,4); a head assembly (2) provided on top of the tanks (3,4) to communicate with the tanks through flow paths (33) at both sides of the head assembly (2). The invention provides stable printing independent of the amount of ink in an ink tank and discharge bubbles in a nozzle head together with the ink. A method of replenishing ink in an on-demand type ink jet print head thus constituted, comprises the step of moving said ink from one tank to the other via said head assembly by varying a pressure of said one tank by said pressure varying means.

摘要： Anhand der Änderung des elektrischen Stromes durch das elektrothermische Wandlerelement (RH) (Heizelement) bei einem nach dem Bubble-Jet-Prinzip arbeitenden Tintenschreibwerk wird gemäß einer Widerstands-Temperaturmeßmethode aufgrund der Temperaturabhängigkeit des Heizelementwiderstandes erkannt, ob sich Tintenflüssigkeit über dem Heizelement (RH) befindet oder nicht. Dabei wird das Heizelement (RH) nicht nur als Aktor, sondern auch als Sensor benutzt. Mit Hilfe einer Strommessung an den Heizelementanschlüssen und anschließender Auswertung des Stromänderungssignals läßt sich eine Aussage über das Vorhandensen von Tintenflüssigkeit gewinnen.
