摘要： A method for double-sided printing may include ejecting printing fluid from a fluid ejector to a platen configured to receive print media, the platen supporting a nonabsorbent substrate. In any sequence, a first print media side and a second print media side may be printed by ejecting printing fluid from the fluid ejector to the first print media side, and contacting the second print media side with the nonabsorbent substrate to transfer printing fluid from the nonabsorbent substrate to the second print media side. A method for double-side printing may further include increasing the contact between the second print media side with the nonabsorbent substrate to increase transfer of printing fluid.

摘要： In various methods, image registration variations among test patterns are used to calibrate misalignment among one or more printheads, paper advance distance, different portions of an inkjet printhead, or bidirectional printhead alignment. A set of test patterns are printed. Each pattern includes a reference portion and a varying portion. The varying portion is changed from pattern to pattern in a manner for testing a parameter being calibrated. An optical sensor scans each test pattern. The parameter setting for the lest pattern having the highest reflectance (i.e., most blank space) is selected as the calibrated parameter value.

摘要： A variable maximum operating temperature for a printhead is defined and utilized within both a system and a method. The variable maximum operating temperature varies according to one or more operating conditions within a printer into which the printhead may be installed. If a detected temperature of the printhead is greater than the variable maximum operating temperature for a detected operating condition, the printer will be shut down to prevent overheating. Accordingly, the system and method extend the useful life of the printhead and reduce paper waste.

摘要： An inkjet drop ejection system comprises a combination of printhead components and ink, mutually tuned to maximize operating characteristics of the printhead and print quality and dry time of the ink. Use of a short shelf (distance from ink source to ink firing element), on the order of 55 microns, provides a very high speed refill. However, it is a characteristic of high speed refill that it has a tendency for being overdamped. To provide the requisite damping, the ink should have a viscosity greater than about 2 cp. In this way, the ink and architecture work together to provide a tuned system that enables stable operation at high frequencies. One advantage of the combination of a pigment and a dispersant in the ink is the resultant higher viscosity provided. The high speed would be of little value if the ink did not have a fast enough rate of drying. This is accomplished by the addition of alcohols or alcohol(s) and surfactant(s) to the ink. Fast dry times are achieved with a combination of alcohols, such as isopropyl alcohol with a 4 or 5 carbon alcohol or with iso-propyl alcohol plus surfactant(s). One preferred embodiment of a short shelf (90 to 130 microns), ink viscosity of about 3 cp, and surface tension of about 54 provides a high speed drop generator capable of operating at about 12 KHz. Reducing the shelf length to about 55 microns, in combination with rotating the substrate at an angle to the scan direction, permits maximum drop generator operation as high as about 20 KHz. As a consequence of employing pigment-based inks, high optical densities are realized, along with excellent permanence (no fade and better waterfastness), and good stability. The combination of preferred ink and pen architecture provides good drop generator stability.
摘要翻译：喷墨墨滴喷射系统包括打印头部件和油墨的组合，其相互调节以最大化打印头的操作特性以及油墨的打印质量和干燥时间。使用大约55微米的短搁架（墨水源到墨水喷射元件的距离）提供了非常高的速度补充。然而，它具有高速补充的特点，它具有过度阻尼的倾向。为了提供必要的阻尼，油墨的粘度应大于约2cp。以这种方式，墨水和结构共同工作，提供了一个可在高频下稳定运行的调谐系统。油墨中颜料和分散剂的组合的一个优点是得到较高的粘度。如果墨水没有足够的干燥速度，高速度就没有什么价值。这通过向油墨中加入醇或醇和表面活性剂来实现。快速干燥时间通过醇，例如异丙醇与4或5个碳醇或与异丙醇加表面活性剂的组合来实现。短架（90-130微米），油墨粘度约为3cp，表面张力约为54的一个优选实施例提供了能够在约12KHz下操作的高速液滴发生器。将搁板长度减小至约55微米，与基板以扫描方向成一定角度的旋转结合使得最大的液滴发生器运转高达约20KHz。作为使用颜料基油墨的结果，实现了高的光密度，以及优异的耐久性（不褪色和更好的耐水性）和良好的稳定性。优选的墨水和笔结构的组合提供了良好的液滴发生器稳定性。
