Abstract: A method for stabilizing a print quality in an inkjet printing system is described. The inkjet printing system can include a nozzle arrangement that may be activated with a number of control signals that can be used to fire ink droplets with corresponding different droplet sizes onto a recording medium. In the method for stabilizing a print quality in an inkjet printing system, a rastered image for an image template can be created. The rastered image can be printable by the inkjet printing system using a subset of the different droplet sizes. Further, the nozzle arrangement can be activated with a control signal for an unused droplet size of the different droplet sizes to induce the nozzle arrangement to generate a prefire pulse.

Abstract: In some examples, a system includes a printhead including a printer fluid nozzle, an air valve in fluid communication with a channel of the nozzle to: (1) create back pressure in the channel when the air valve is closed and printer fluid is ejected through the nozzle and (2) release back pressure in the channel when the air valve is open, an ejector to eject printer fluid through the nozzle to form a meniscus of printer fluid in the channel when the air valve is closed, a pressure sensor to measure pressure within the channel, and an indicator in electrical communication with the pressure sensor. The indicator can, for example, indicate whether there is an air leak in the channel by determining whether the pressure in the channel is within a predetermined pressure range after a predetermined idle time following the formation of the meniscus in the nozzle.
