    摘要： An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.

    摘要翻译： 喷墨打印机包括供墨系统和具有用于喷射墨滴的喷嘴的打印头。 打印机通过将在预定时间内喷射的墨滴的数量与在该时间期间通过打印机墨水供应系统输送的墨水的量进行比较来确定喷射墨滴的平均尺寸。 如果确定的平均墨滴大小与预定的墨滴尺寸标准不匹配，则打印机调节喷墨嘴的激活信号以改变墨滴尺寸。 固体墨水打印机通过计算通过供墨系统中的预定点的全部或部分墨水棒的数量来确定通过墨水供应系统输送的墨水的量。 计数器检测形成在墨棒的外表面上的感测元件。 示例性检测器包括机械臂或热敏电阻，用于检测由于熔化的墨棒的横截面积的变化而导致的打印机熔体温度的变化。
