    • An at least two-pass acoustic printing system uses an acoustic printhead having an array of ejectors arranged in rows and columns. Operation of each ejector is individually controllable. To minimize cross-talk errors a first selected ejector in a selected row is identified as an odd ejector of the selected row. Thereafter a first firing sequence of the first selected ejector is generated based on the first selected ejector being identified as odd. Then a second ejector, immediately adjacent the first ejector, is selected and is identified as an even ejector. Thereafter a second firing sequence is generated for the second selected ejector based on the selector being identified as even. The first and second firing sequences result in the first ejector and the second ejector being active during non-concurrent time periods. When a defective ejector of the array is detected, an operable ejector firing to the same substrate area is determined. A firing sequence from or associated with the defective ejector is transferred to be used by the operable ejector wherein the operable ejector fires both its own firing sequence and the firing sequence of the defective ejector.
    • 至少两声道声音打印系统使用具有排列成行和列的排列阵列的声学打印头。 每个喷射器的操作是可以单独控制的。 为了最小化串扰错误,所选行中的第一选择的喷射器被识别为所选行的奇数喷射器。 此后,基于第一选择的喷射器被识别为奇数来生成第一选择的喷射器的第一喷射序列。 然后选择紧邻第一喷射器的第二喷射器,并被识别为均匀喷射器。 此后,基于选择器被识别为偶数,为第二选择的喷射器生成第二点火序列。 第一和第二发射序列导致第一喷射器和第二喷射器在非并发时间段期间是活动的。 当检测到阵列的有缺陷的喷射器时,确定对相同基板区域的可操作的喷射器发射。 来自或与有缺陷的喷射器相关联的发射序列被转移以由可操作的喷射器使用,其中可操作的喷射器触发其自身的击发序列和有缺陷的喷射器的击发序列。
