摘要： A printhead 21 for an inkjet printer 10 having geometric features which reduce drop placement error of main 6 and satellite 8 drops ejected from the nozzles 82 of the printhead 21. Nozzles 82 that are tilted along an axis 85 corresponding to the direction of scanning of the printhead 21 while printing have reduced drop placement error 19' in the orthogonal direction 4 to the scanning, and create a breakoff velocity 5s for the satellite drop 8 that can cause the main 6 and satellite 8 drops to be placed in a coincident location on the medium 18 in one of the directions of scanning, thus forming desireable round printed spots and reducing drop placement error in the scan direction. These improvements can be repeatably achieved for all nozzles 82. Nozzles 82 with non-circular and asymmetric bores 82b-g also reduce drop placement errors, particularly when these types of nozzles 82 are also tilted.
摘要翻译：具有几何特征的喷墨打印机的打印头21，其具有减少从打印头21的喷嘴82喷出的主体6和卫星8的滴落误差。喷嘴82沿轴线85倾斜，对应于扫描方向打印头21在扫描的正交方向4上具有降低的放置位置误差19'，并且为卫星下落8产生能够导致主6和卫星8的放置位置在重合位置上的断裂速度5s 介质18在扫描方向中的一个方向上，从而形成所需的圆形印刷点并减小扫描方向上的放置误差。对于所有喷嘴82，可以重复地实现这些改进。具有非圆形和不对称孔82b-g的喷嘴82也减小了滴落布置误差，特别是当这些类型的喷嘴82也倾斜时。

摘要： A printer (20) automatically selects the print mode depending upon media type. The printer has a media handler (30) to convey media through the printer and a media sensor (32) to detect whether the media is transparent. The printer also has a printing mechanism (34) configured to print a print file (44) using a print mode that is selected based upon the type of media (36) detected by the media sensor (32) and whether the print file (44) is intended for that media type.

摘要： An inkjet printer (10) uses a printhead (12) that passes repeatedly across a print medium in individual swaths. The printhead (12) has individual nozzles (21) that are fired repeatedly during each printhead swath to apply an ink pattern to the print medium. Before any given swath, the printer (10) analyzes factors that might require a reduction in print density. Anticipated printhead temperature is one factor that might require a reduction in print density. The printer (10) monitors the print density and peak printhead temperature during each printhead swath. It then uses these values to calculate, prior to each new swath, a maximum permissible print density. If a reduction in print density is required, the printer (10) temporarily disables selected nozzles (21) to produce a reduced-height swath rather than pausing between swaths or reducing the printhead velocity relative to the page.

摘要： An on-page inkjet printhead spitting system purges the printhead (34, 36) nozzles across a printed page (78, 80), and occasionally in the conventional service station spittoon (70). In addition to the image-forming droplets, extra purging droplets are fired to maintain pen health. To determine when to purge each nozzle, the number of times each nozzle is fired to print the image (80) is counted or estimated, or printhead characteristics are monitored. The purging dots may be located on the page (78), in the spittoon (70), or both. On the page (78), the purging dots may be hidden from view, in the image background (92) or over the image dots (82, 84, 85, 86, 90), or hidden in plain sight adjacent image dots, in speed bars (94, 96), in a watermark type design (98), or in a repeating pattern. Use of this on-page spitting system conserves ink and improves throughput of the printing mechanism (20), without requiring any sacrifice in the print quality appearance to the naked eye.
