Method and apparatus for ink-jet drop trajectory and alignment error detection and correction |
摘要 |
A method and apparatus for ink-jet drop generator ink drop characteristics uses a drop detector target mounted in the printing zone of a hard copy apparatus. The detector target includes a matrix of individual elements sized approximately the same as pixel targets in printing operations. A detector target is mounted adjacently to the paper path of the apparatus such that test firing can be accomplished prior to each swath scan across the print media. By pre-firing nozzles to be used in the next swath at the detector target, actual trajectory errors and drop volumes can be analyzed in real-time. Alternate embodiments and methods are described.
