Liquid ejecting apparatus, and non-transitory, computer-readable media therefor

摘要

A liquid ejecting apparatus may have a head with a plurality of head units. Each head unit may include a driver IC. An ejection timing signal (FIRE) may be transmitted from a control device to each of the driver ICs through an ejection timing signal line, which may be connected to the control device as a single line and split on its way to the driver ICs. The control device may further output delay information indicating a delay amount for the FIRE signal to the driver ICs through a control signal line through which a waveform pattern selection signal (SIN) is also transmitted. Each of the driver ICs may include a delay circuit that delays the FIRE signal by the delay amount indicated by the delay information.
