Fluid flux correction is disclosed. An example method of fluid flux correction includes displacing a fluid volume in a fluid reservoir with a compliant element. The method also includes absorbing fluid surges caused by variations in fluid flux to reduce distortion of at least one ink nozzle meniscus and maintain consistent fluid ejection.

Cleaning apparatus and method of assembly therefor for cleaning an inkjet print head. The cleaning apparatus comprises a web supply for supplying a cleaning web therefrom and a web receiver for receiving the web. A web drive drives the web from the web supply to the web receiver. The web drive pulls the web from the web supply with a first tension force and also pulls the web onto the web receiver with a second tension force greater than the first tension force, so that the web is wrinkle-free while the web slidably engages an exterior surface of the print head to clean the print head. The web remains wrinkle-free to ensure that the surface of the web will contact the surface of the print head without gaps in contact coverage. This enhances cleaning effectiveness compared to a cleaning web having wrinkles.
