    Abstract: A fluid delivery system may include a fluid reservoir that may include a fluid supply port through which fluid is supplied to the fluid reservoir, a fluid outlet port through which a first portion of discharged fluid is supplied from the reservoir to a fluid ejection device, a fluid inlet port through which a second portion of the discharged fluid is recirculated back to the reservoir and through which air is pushed into the reservoir and an atmospheric vent to vent the air, that was pushed into the reservoir through the fluid inlet port, from the reservoir.

    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.

    Abstract translation: 一种方法包括将标称背压施加到流体喷射组件和喷嘴以通过背压调节器在其中形成第一量的背压。 该方法还包括施加第一压力以降低流体喷射组件和喷嘴内的第一量的背压，以响应于清洁操作的激活，通过加压模块在其中形成第二数量的背压。 该方法还包括将流体喷射组件和芯吸构件中的至少一个彼此移动以执行清洁操作。 芯吸构件相对于流体喷射组件移动并抵靠喷嘴表面，以将来自喷嘴表面和喷嘴中的至少一个的流体残余物传送到芯吸构件的一部分以形成使用的芯吸构件部分。
