摘要： An image forming apparatus having a pair of fuser rollers for fusing toner onto the surface of recording sheets. The apparatus further includes an oil applicator mounted for dispensing oil onto at least one of the fuser rollers. The oil applicator includes a tank for holding oil, a pad disposed adjacent to one of the rollers for applying oil thereto, and an oil reservoir mounted adjacent the pad and connected to the tank for receiving oil therefrom. The oil reservoir includes an ejection port that permits oil within the reservoir to be dispensed to the pad. A flexible diaphragm extends over at least a portion of the oil reservoir, and a seal is secured to the diaphragm. At least one piezo element is secured to the diaphragm for moving the diaphragm and seal between two positions in response to the piezo element being selectively operable between engaged and non-engaged states. In one of the positions the seal effectively closes the oil reservoir ejection port, while in the other position the seal is spaced from the ejection port such that oil may flow from the oil reservoir through the ejection port and to the pad.

摘要： The level of powdered toner in a toner reservoir of a printer or copier is determined by ascertaining the time that it takes a stirring paddle to rotate from a second of two fixed ridges adjacent the top of the reservoir until the toner is engaged. A sensor, which is preferably a piezoelectric element or a strain gauge, is preferably mounted on the end of the stirring paddle to engage each of the two fixed ridges. When the sensor flexes after engaging each of the ridges, two closely spaced electrical pulse are produced. When the sensor engages the toner, another electrical pulse is produced, and the time between the second and third pulses is used to determine the level of the toner in the toner reservoir. If the stirring paddle is flexible, it may engage the ridges and the toner so that the sensor could be mounted on the stirring paddle to not engage the ridges or the toner but only to sense flexing of the stirring paddle for producing the electrical pulses. Instead of using the ridges, an emitter wheel may be employed to produce a pulse when the stirring paddle is in its substantially vertical position.

摘要翻译： 打印机或复印机的调色剂储存器中的粉末调色剂的水平通过确定搅拌桨从邻近储存器顶部的两个固定脊中的第二个旋转所需的时间来确定，直到调色剂接合为止。 优选地，传感器（其优选地是压电元件或应变计）安装在搅拌桨的端部上以接合两个固定脊中的每一个。 当传感器在接合每个脊之后弯曲时，产生两个紧密间隔的电脉冲。 当传感器接合调色剂时，产生另一个电脉冲，并且使用第二和第三脉冲之间的时间来确定调色剂储存器中调色剂的水平。 如果搅拌桨是柔性的，则它可以接合脊和调色剂，使得传感器可以安装在搅拌桨上以不接合脊或调色剂，而只是感测搅拌桨的弯曲以产生电脉冲。 代替使用脊，当搅拌桨处于其基本垂直的位置时，可以使用发射轮产生脉冲。
