A print module includes: a body housing at least one printed circuit board (PCB); an air inlet and an air outlet positioned in a roof of the body; an air pathway extending through the body between the air inlet and the air outlet; and an inkjet printhead positioned at a lower part of the body opposite the roof, the inkjet printhead electrically communicating with the PCB.

A recording apparatus includes a switching mechanism which switches a motive force transmission state from a motive force source, includes a sun gear which is driven by the motive force source, a planet gear which performs planetary motion around the sun gear, a rotational movement member which causes the planet gear to perform planetary motion by rotationally moving, and a regulating member which engages with a regulated portion which is provided in the rotational movement member to restrict the rotational movement of the rotational movement member.

A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid from a plurality of nozzles disposed in a nozzle surface, a wiping member that wipes the nozzle surface, and a wiping member moving mechanism that moves the wiping member between a wiping position where the nozzle surface is wiped and a retracted position. The wiping member moving mechanism has a wiping member holding mechanism that holds the wiping member and a holding state releasing mechanism that releases a holding state of the wiping member holding mechanism in a case where a load that is equal to or higher than a set value is received.

A capping assembly includes a capper having a perimeter seal for sealing engagement with the printhead. The capping assembly has an enclosed capping volume when the capper is sealingly engaged with the printhead, whereby the capping volume is variable in response to relative differences in pressures inside and outside the capping volume.

There is provided an inkjet printing apparatus capable of efficiently performing print preparation in a standby state. For this purpose, the inkjet printing apparatus includes: a cap moving unit for bringing a cap member for protecting an ejection opening surface of a print head into or out of intimate contact with the ejection opening surface; and a positioning unit for positioning the print head so as to achieve a printing operation. The positioning unit allows a reference portion disposed at the print head to abut against a distance defining member for defining a predetermined distance between the ejection opening surface 8a and the platen so as to position the print head. At this time, the distance defining member is inserted into a portion at which the reference portion can abut in association with operation in which the cap moving unit separates the cap member from the ejection opening surface.

A print module includes: a body housing first and second opposed printed circuit boards (PCBs), each of the first and second PCBs having heat-generating electronic components; an air inlet and an air outlet positioned towards an upper part of the body; an air pathway extending between the air inlet and the air outlet; a plurality of heatsinks, each heatsink being thermally coupled with one of the heat-generating components and having an array of cooling fins extending into the air pathway; and an inkjet printhead receiving power and print data from at least one of the first and second PCBs. The inkjet printhead is positioned toward a lower part of the print module.

In one example in accordance with the present disclosure, a printhead cap system is described. The printhead cap system includes a cap having an elastomer seal to surround a printhead die on a print cartridge. The printhead cap system also includes a variable force capping station to retain the cap. The variable force capping station is to move the cap to 1) a first position wherein the cap exerts a first force on a substrate on which the printhead die is disposed and 2) a second position wherein the cap exerts a second force on the substrate. In an example, the second force is greater than the first force. The printhead cap system also includes a control system to raise the cap from an uncapped position through the first position and the second position.

A maintenance unit is provided to be mounted on a liquid discharge apparatus including a discharge portion that performs printing by discharging a liquid from a nozzle to a medium when the printing is not performed, and includes a cap configured to form a space in which the nozzle is open, and a pump configured to depressurize the space.

A printhead capping system includes: a fixed plate; first and second sliders slidably movable along the fixed plate; a mounting bracket having a cap assembly mounted thereon; and first and second arms interconnecting the mounting bracket and the respective first and second sliders. Movement of the first and second sliders towards each other causes lateral movement of the cap assembly away from the fixed plate, and movement of the first and second sliders away from each other causes lateral movement of the cap assembly towards the fixed plate.

A liquid ejecting apparatus includes a liquid ejecting portion that has a nozzle and an opening surface in which the nozzle opens and that ejects a liquid from the nozzle toward a medium that is transported along a transport path, a wiper member that wipes the liquid ejecting portion while moving, a guide that guides movement of the wiper member, and a cap that has an opening portion and that is movable between a capping position at which the cap contacts the liquid ejecting portion so that the opening portion surrounds the nozzle and an open position at which the cap is apart from the liquid ejecting portion. When the cap is at the open position vertically below the guide, the opening portion is at least partially covered by the guide.
