Examples include a method for priming a printhead that comprises a bag associated with a pump. A first control signal, which corresponds to a first target pressure, is applied to the pump. Directly after the application of the first control signal, a second control signal, which corresponds to a second target pressure, is applied to the pump. The second target pressure is lower than the first target pressure.

Priming printheads

Disclosed herein is a print head maintenance assembly, a printing device and a method of controlling a print head maintenance assembly in a printing device. The print head maintenance assembly comprises a maintenance cartridge comprising a positioning flag, wherein the maintenance cartridge is movable along a maintenance path in a direction of movement; and a sensor to detect the positioning flag to determine the position of the maintenance cartridge along the maintenance path.

Print head maintenance assembly

There is provided a maintenance apparatus to, while in a service zone, perform a cleaning operation of a set of printheads within a carriage. The maintenance apparatus comprises a cleaning structure and an actuation mechanism. The actuation mechanism is arranged to position the cleaning structure between an engaged configuration and a disengaged configuration. The disengaged configuration is activated by a first triggering element associated to the carriage interacting with the actuation mechanism subsequent to a cleaning operation. The engaged configuration is activated by a second triggering element as the carriage moves away from the service zone.
