摘要： A printer apparatus and method of actuating a fluid pump in a printer to deliver fluid to an ink jet printhead without removing the printhead from a printhead carriage particularly useful for priming inkjet printheads using an air displacement pump to deliver air under positive pressure to the printheads. The pump is located proximate a service station on the printer and is automatically actuated by movement of the carriage to service station. The pump may be arcuately positionable to align the pump with a selected one of air passageways provided in a printhead holddown cover on the printhead carriage. Algorithms are provided for locating the precise position of the pump outlet along the carriage scan axis relative to its intended design location and for arcuately positioning the pump relative to the carriage to engage the pump outlet with a selected one of conduits in the carriage connected to each printhead.

摘要： A calibration technique, for a printer having a plurality of different color ink printheads, which includes printing and scanning a test pattern. The test pattern is printed by each printhead printing a plurality of swaths having a length and distanced apart from each other. An optical sensor is used to scan the printed test pattern. Calibration is performed for each head by reading the swath length and the relative spacing of the swath and comparing the length to the spacing. This comparison is used to find the directional error for each head.

摘要： Techniques to compensate for random and systematic errors when measuring dot placement errors. Error accumulation due to scan axis irregularities during printhead calibration is minimized by swapping alignment block positions on the print medium from swath to swath. Print media advances during the calibration are minimized by the use of a moving reference instead of a constant reference; adjacent groups of nozzles are used to calibrate the following group. Only a small media advance is needed to print alignment blocks using adjacent nozzle groups one beside the other to be calibrated. To prevent paper slip accumulative errors when using moving references, the order of the groups of nozzles is swapped from one paper advance to the other. This randomizes for small, unavoidable slips when advancing the paper and prevents error accumulation. No further paper advances are used at all for the rest of the dot placement calibration (odd to even columns in a print-head, pen to pen correction and bidirectional correction). When calibrating X-axis position for a group of nozzles, a group of nozzles located at the same Y-axis coordinate is used, so that no paper advances are needed to print them one beside the other.
摘要翻译：测量点位置误差时补偿随机和系统误差的技术。在打印头校准期间由于扫描轴不规则造成的误差累积通过将打印介质上的对准块位置从条纹交换到条带来最小化。通过使用移动参考而不是恒定参考来最小化校准期间的打印介质进给; 相邻的喷嘴组用于校准以下组。只需要一个小介质提前打印校准块，使用相邻的喷嘴组，一个在另一个旁边进行校准。为了防止在使用移动参考时出现纸张滑移累积误差，喷嘴组的顺序从一个纸张提前交换到另一个。当纸张推进时，会随机分配小的不可避免的单据并防止错误累积。对于剩余的点位置校准（打印头中的奇数到偶数列，笔到笔校正和双向校正），根本不使用进一步的纸张。当校准一组喷嘴的X轴位置时，使用位于相同Y轴坐标处的一组喷嘴，因此不需要纸张前进来打印它们。

摘要： A misalignment compensation technique for a dot printer is disclosed. This technique first supplies printing instructions to a printhead for energizing printing elements in various groups (primitives) to print a pattern on a medium. The printed pattern is then detected by optical sensors in the printer. Based on the detection, a position offset error for each primitive is determined. These errors are used to generate a separate time correction for each of the primitives such that, when the printer is used normally, the time period for printing a dot will be advanced or delayed for each primitive so as to align the dots printed by the primitives. In another embodiment, alignment data taken by a manufacturing line sensor is stored in a memory on the print cartridge. After the print cartridge is installed in the printer, a second optical test completes the data needed to create timing correction values.

摘要： A method and apparatus for correcting for drop placement errors due to relative rotation between an inkjet printhead mounted in a printer carriage and the print media to be printed on comprises first determining the relative contribution to the drop placement error due to rotation of the printhead about the scan axis (Y axis error), then, with respect to any determined Y axis error, applying the same magnitude and sense of correction for drop placement errors while printing in both a first scanning direction of the carriage and while printing in a second scanning direction of the carriage. Errors due to rotation about the Z axis are also corrected for. Preferably the errors are determined by printing and scanning a test pattern.
