摘要： A method of operating an inkjet printer reduces ink drop placement errors in a process direction. The method includes generating firing signals for inkjets in a printhead at a first frequency and initiating the generation of the firing signals to a first plurality of inkjets in the printhead at a second frequency, the first frequency being greater than the second frequency.

摘要： To generate a toner cloud in a development system, a first potential is applied to a donor roll for a first pulse time to project toner from the donor roll toward a photoreceptor; a second potential is applied to the donor roll for a second pulse time to slow the speed at which the toner is projected toward the photoreceptor; a third potential is applied to the donor roll for a third pulse time to hold toner between the donor roll and the photoreceptor; and a fourth potential is applied to the donor roll for a fourth pulse time to urge undeveloped toner to the surface of the donor roll. Voltages may also be applied for selectivity removing toner from a donor roll.
