Abstract: In some examples, a method includes, in response to a fluid firing unit being operated according to a normal printing mode, applying a first voltage to the fluid firing unit to fire the fluid firing unit during a printing operation. The method further includes determining, using a sensor, whether a predetermined condition is met, and in response to determining that the predetermined condition is met, operating the fluid firing unit according to a recovery mode in which a second voltage higher than the first voltage is applied to the fluid firing unit to clean the fluid firing unit.

Abstract: A cleaning module includes an actuator device, a fluid chamber, and a wiper member. The actuator device may enter an activation state based on a movement of at least a portion of the actuator device in response to an engagement with the printhead. The fluid chamber may store and supply fluid to the porous wipe material in response to the activation state of the actuator device. The wiper member may apply pressure to a porous wipe material including the fluid therein to wipe the printhead.

Abstract: A method for controlling the amount of printing fluid deposited by a printhead for a plurality of passes of a swath width of a printing process is described. The printing process may include periodic servicing of the printhead. The method may include determining an amount of printing fluid to be deposited for each pass of the swath width; identifying which pass of the swath width servicing is to occur; and reducing the determined amount of printing fluid deposited during a first pass immediately following servicing of the printhead.

Abstract: Examples in accordance with the present disclosure are directed to a method including generating a negative fluid pressure between a fluid supply and a first port of a fluidic ejection device, and generating a positive fluid pressure between the fluid supply and a second port of the fluidic ejection device. The method further includes selectively activating a first priming pump connected to the first port in response to an indication that the first port is transitioning from an open state to a closed state, wherein the selective activation of the first priming pump causes the first port to remain in the open state and causes fluid within the fluidic ejection device to exit through the first port and to recirculate along a fluid flow path.

Abstract: In an example, a machine-readable medium stores instructions which when executed by a processor cause the processor to determine a difference between a measured printed output and an expected printed output. Based on the difference, a first control instruction for controlling a drop size wherein the drop size is variable, and a second control instruction for controlling a dot density of a variable dot density may be determined.
