Abstract
A method includes applying a nominal back pressure to a fluid ejection assembly and nozzles to form a first amount of back pressure therein by a back pressure regulator. The method also includes applying a first pressure to lower the first amount of back pressure within the fluid ejection assembly and the nozzles to form a second amount of back pressure therein by a pressurization module in response to an activation of a cleaning operation. The method also includes moving at least one of the fluid ejection assembly and a wicking member against each other to perform the cleaning operation. The wicking member moves relative to the fluid ejection assembly against and across the nozzle surface to transfer fluid residue from at least one of the nozzle surface and the nozzles to a portion of the wicking member to form a used wicking member portion.
