A printing unit includes: a sleeve and a print module received in the sleeve, the print module being slidably removable, in a first direction, from the sleeve. The print module includes a supply module and a replaceable printhead. The printhead is slidably removable, in a second direction, from the supply module, the first and second directions being non-parallel.

A printing system may comprise a page wide array printhead a capping station, and a number of modular caps comprising a housing to cover a nozzle array of a printhead and a cap coupler coupled to the housing to couple the cap to the nozzle array in which the modular caps are adapted to be coupled to and removed from the nozzle array of the printhead and stored in the capping station.

A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.

A non-transitory computer readable medium storing computer readable instructions configured to, when executed by a processor of a computer, cause the processor to: perform a print instruction receiving process comprising receiving a print instruction from an operating system; in response to receiving the print instruction, perform a preparation instruction process comprising transmitting preparation instruction information to a printer, the preparation instruction information being information for instructing execution of at least a part of at least one pre-printing operation, the at least one pre-printing operation being executed by the printer to record an image having particular quality in the printing operation, the particular execution condition being the execution condition changing operation content of the at least one pre-printing operation; in response to executing the preparation instruction process, perform a generating process comprising generating print data; and perform a print instruction process comprising transmitting print instruction information to the printer.

A controller of an inkjet printing apparatus is configured such that, in response to receipt of a preceding command, which notifies transmission of a recording command in advance, from an information processing device through the communication device, the controller executes a separating process to move from a covering position to a spaced position, a moving process to move a carriage, from which the cap is separated, from a first position to a second position, a flushing process to cause the inkjet head to eject the ink toward an ink receiver in response to receipt of a recording command instructing recording of an image on the sheet and upon completion of the moving process, and a recording process to cause a conveyer to convey the sheet and cause the inkjet head to eject the ink in accordance with the recording command, in response to completion of the flushing process.

A controller of an inkjet printing apparatus is configured to raise a driving voltage to a target voltage, move the cap for an inkjet head from a covering position to a spaced position, and move a carriage, from which the cap is spaced, from a first position to a second position, simultaneously. The controller is further configured to cause the inkjet head to eject the ink toward an ink receiver in response to completion of boosting of the driving voltage and moving of the cap to the spaced position, and cause the conveyer to convey the sheet and cause the inkjet head to eject the ink in accordance with the recording command, in response to receipt of a recording command which instructs recording of an image on the sheet through a communication device, and completion of flushing.

A printer includes a printhead assembly, a spit zone, and a controller. The printhead assembly includes nozzles to eject ink drops. The spit zone is to store maintenance ink. The controller is to move the printhead assembly over the spit zone while ink is ejected from the nozzles during spits.

An apparatus for a fluidic ejection device and a fluidic ejection device containing the apparatus. The apparatus includes a pivot member having at least a first position and a second position, a shaft attached on a first end thereof to the pivot member and on a second end distal from the first end to a capping structure, wherein pivot of the pivot member pivots the capping structure from a first capped position to a second uncapped position adjacent an ejection head of the fluidic ejection device.

The liquid discharge apparatus includes a liquid discharge head having nozzles formed therein, to discharge liquid from the nozzles and a cap to contact with or separate from the liquid discharge head to maintain the liquid discharge head. The liquid discharge head includes a common chamber connected to the nozzles, a liquid supply port provided at one end of the liquid discharge head in a longitudinal direction of the liquid discharge head to supply liquid to one end of the common chamber, and a liquid discharge port provided at another end of the liquid discharge head in the longitudinal direction to discharge liquid, which flows through the common chamber and is not discharged from the nozzles, from another end of the common chamber. The cap includes a drainage supply port to be connected with the liquid discharge port of the liquid discharge head with a connection path.

A valve driving device including a primary liquid chamber, a secondary liquid chamber, a valve body that opens and closes a communication flow channel through which the primary liquid chamber and the secondary liquid chamber are in communication, a pressure receiving member that partitions the secondary liquid chamber and atmospheric air in a liquid tight manner, and an operation member that opens and closes the valve body by transmitting the reaction of the pressure receiving member to the valve body, in which the pressure receiving member includes a pressure receiving plate portion that operates the operation member, and a pressure receiving film portion that is provided in the periphery of the pressure receiving plate portion, the valve driving device including a pressing driving portion that removes pressing of the pressure receiving plate portion prior to that of the pressure receiving film portion.
