摘要: A printhead for a printer has actuating elements ejecting fluid, and drive circuit selectively applying waveform having several slopes, to an element, according print signal. resulting lesser sensitivity changes of slew rate in one slope the than change another. The variable resistance circuit, control adjust trim By making adjustment less sensitive, signal can have more relaxed tolerances, thus employ simpler, cheaper circuitry.
