摘要： An improved media-width phase-change ink-jet print had (102) maintains a uniform temperature across its width to produce consistent drop mass and uniform print quality. The print head uses a heater (120) including two separately controlled, overlapping heating zones (154). The heating zones produce heat gradients (170, 172) that have maximum outputs toward opposing edges (168a, 168b) of the print head and are controlled in response to thermistors (138s, 168b) positioned at the corresponding edges. The two heating zones together produce a linear heat gradient (180) across the print heat to compensate for uneven head-to-drum spacing (166) and other unsymmetrical thermal loads on the print head. The improved print head also includes baffles (192) that reduce air flow between the head and the attached reservoir (118), and thermal breaks (218) that insulate the section (220) of the head that includes the jets from the thermal gradients at the edges of the print head.
摘要翻译：改进的介质宽度相变喷墨印刷（102）在其宽度上保持均匀的温度，以产生一致的液滴质量和均匀的打印质量。打印头使用包括两个分开控制的重叠加热区（154）的加热器（120）。加热区产生对打印头的相对边缘（168a，168b）具有最大输出的热梯度（170,172），并响应于位于相应边缘的热敏电阻（138s，168b）来控制。两个加热区域一起在打印热量上产生线性热梯度（180），以补偿打印头上不均匀的头对鼓间距（166）和其他不对称的热负荷。改进的打印头还包括减少头部和附接的储存器（118）之间的空气流动的挡板（192），以及热断裂（218），其将包括射流的头部的部分（220）与热梯度隔离打印头的边缘。

摘要： A method of operating a printer enables the mass of the ink drops ejected by the printheads in the printer to maintained in an optimal range without measuring the drop mass being ejected by the inkjets in the printheads. After calibration of the printheads, the printheads are operated with electrical signals having different peak-to-peak voltages. The number of inoperable inkjets for each printhead is determined from image data of the ejected ink on the image receiving member and the number of inoperable inkjets for each printhead is compared to a predetermined threshold. The peak-to-peak voltage for the electrical signals used to operate a printhead is adjusted with reference to the number of inoperable inkjets and the predetermined threshold.

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： A drop-on-demand ink jet print head (9) has an ink pressure chamber (22) coupled to a source of ink (11) and an ink drop ejecting orifice (103) with an ink drop ejection orifice outlet (14). An acoustic driver (36), in response to a driver signal (100), produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop ejecting orifice (103) and the ink jet ejection orifice outlet (14) of the ink jet print head (9). In accordance with the present invention, controlling the operation of the ink jet print head (9) with a particular drive signal reduces print quality degradation resulting from rectified diffusion, which is the growth of air bubbles dissolved in the ink from the repeated application of pressure pulses to the ink residing within the ink pressure chamber (22) of the ink jet print head (9), such pressure pulses causing the application of pressures below ambient pressure. This method of controlling the operation of the ink jet print head (9) applies pressure below ambient pressure to the ink residing within the ink pressure chamber (22) of the ink jet print head (9) at magnitudes less than the threshold pressure magnitude that leads to the air bubble growth.
