Provided is a liquid discharging apparatus including a liquid discharging unit configured to discharge a liquid, and a dummy discharge receptacle including an absorbing member configured to absorb a liquid dummy-discharged by the liquid discharging unit, wherein the liquid discharging unit discharges a liquid having a resin content of 5% by mass or greater, and wherein the absorbing member of the dummy discharge receptacle is formed of melamine foam.

To prevent a printing head not placed on a cleaning placing unit from being cleaned and prevent contamination of an ambient environment by cleaning liquid. An ink jet recording system includes a placement detecting unit configured to detect that a printing head 1 is placed on a cleaning placing unit 200. The placement detecting unit is configured to, when detecting that the printing head 1 is placed, transmit a signal based on placement confirmation for the printing head 1 to a controller connected to the printing head 1 placed on the cleaning placing unit 200.

Systems and methods are provided for adaptive printhead cleaning. One embodiment is a printer maintenance system that includes memory to store defect information of a group of nozzles of a printer, and a processor to determine whether the group of nozzles have a number of nozzle defects that exceeds a threshold based on the defect information. In response to a determination that the threshold is exceeded, the processor determines a type of cleaning operation, a cleaning duration, and a cleaning intensity to perform for the group of nozzles based on the defect information. The processor then initiates a cleaning operation for the group of nozzles according to the type of cleaning operation, the cleaning duration, and the cleaning intensity determined for the group of nozzles.

An example of a printing apparatus comprising a scanning printhead and a controller is disclosed. The scanning printhead comprises a plurality of nozzles to print using a mask comprising a ramp area and non-ramp area. A first subset of nozzles of the plurality of nozzles is assigned to the ramp area and the second subset of nozzles of the plurality of nozzles is assigned to the non-ramp area. The controller is to calculate a number of spits of a nozzle from the second subset of nozzles for a pass. The controller is also to calculate a number of spits of a nozzle from the first subset of nozzles for the pass based on the number of spits of the nozzle from the second subset of nozzles. The controller is further to instruct the nozzle from the first subset of nozzles to eject online an amount of a composition on a service zone based on the number of spits of the first subset of nozzles.

An example of an apparatus is provided. The apparatus includes a printhead to dispense a first print fluid and a second print fluid. In addition, the apparatus includes a first nozzle disposed on the printhead. The first nozzle is to eject a first plurality of drops of the first print fluid. The apparatus also includes a second nozzle disposed on the printhead. The second nozzle is offset from the first nozzle by an offset distance along a relative direction of media travel. The second nozzle is to eject a second plurality of drops of the second print fluid. Furthermore, the apparatus includes a textile to receive the first plurality of drops and the second plurality of drops. The textile is to be moved relative to the printhead by the offset distance between ejection of the first plurality of drops and the second plurality of drops.

A circuit 108 for controlling a plurality of fluid dispense nozzles 202(N), the circuit 108 to change an order in which the fluid dispense nozzles 202(N) are actuated.

There is disclosed a method comprising determining, by a processor, if there are consecutive nozzles of a print apparatus that are occluded by a contaminant; and, when a predetermined number of consecutive nozzles are occluded, automatically triggering a cleaning operation to at least partially remove the contaminant.

Systems and methods are provided for adaptive ink flushing of a printer. One embodiment is an apparatus that includes an adaptive ink flushing controller configured to obtain nozzle firing data for a nozzle of a printhead, to analyze the nozzle firing data to determine an inactive firing span of the nozzle, and, in response to determining that the inactive firing span of the nozzle exceeds a threshold, to transmit a firing instruction for ejecting ink.

When performing on-sheet preliminary ink ejection, a control unit (a) determines a nozzle that performs the on-sheet preliminary ink ejection, (b) randomly selects on a print sheet an ejection position candidate of an ink droplet ejected from the determined nozzle, (c) determines whether the selected ejection position candidate is included by a mask area that includes a postprocessing object, (d1) if the selected ejection position candidate is not included by the mask area, sets as the selected ejection position candidate an ejection position of an ink droplet ejected from the determined nozzle, and (d2) if the selected ejection position candidate is included by the mask area, does not set as the selected ejection position candidate an ejection position of an ink droplet ejected from the determined nozzle and sets an ejection position of an ink droplet ejected from the determined nozzle outside of the mask area.

Devices include an inkjet printhead having nozzles and a transport item adjacent the nozzles. The transport item includes vacuum openings adapted to maintain print media on the transport item. The transport item moves the print media in a processing direction. The transport item also includes a jetting area lacking the vacuum openings. The jetting area is elongated and is oriented perpendicular to the processing direction. The nozzles are controlled to eject ink to the jetting area when the nozzles are aligned with the jetting area.
