Abstract
In a method for controlling printing elements of an ink print head, an idle time between the ejection of two dots from the same nozzle is determined. In the event that the idle time exceeds a predetermined threshold (Δt), a determined number of vibration cycles is performed (e.g. in immediate succession). The number of vibration cycles is determined based on the idle time, such that more vibration cycles are performed the longer that the idle time lasts between the ejections of two dots from the same nozzle.
