The inkjet printhead is positioned toward a lower part of the print module.

A waste liquid collection apparatus includes a waste liquid tray, a collection tank, a collection pump, and a circulation pump. The waste liquid tray includes a waste liquid receiving surface inclined downward to receive a waste liquid discharged from a head unit and allow the waste liquid to flow from an upper end to a lower end of the waste liquid receiving surface, and a waste liquid discharge part that is disposed adjacent to the lower end of the waste liquid receiving surface to discharge the waste liquid. The collection pump feeds a part of the waste liquid discharged from the waste liquid discharge part to the collection tank. The circulation pump returns another part of the waste liquid discharged from the waste liquid discharge part to the upper end of the waste liquid receiving surface to circulate the other part of the waste liquid.

Provided is a cap unit that can prevent or suppress collision between the drive gear and intermittent gear when the drive gear and intermittent gear begin to mesh. A cap unit 25 has a moving mechanism 28 that moves a cap 26. The moving mechanism 28 has an intermittent cam gear 36 with a cam channel 43; a drive gear 35; and a cap holder 45. The cap holder 45 includes a holding member 48 that holds the cap 26; a cam follower pin 49; a pin support mechanism 50 that supports the cam follower pin 49; and a coil spring 51 that urges the cam follower pin 49 toward the bottom 43a of the cam channel 43. A slope 57 is disposed to the bottom 43a of the cam channel 43. The cam follower pin 49 is on the slope 57 when meshing of the intermittent cam gear 36 and drive gear 35 is disengaged, and the intermittent cam gear 36 turns in conjunction with the cam follower pin 49 moving on the slope 57 due to the urging force of the coil spring 51.

There is provided an ink-jet printer, including: a conveyor; a carriage; a recording head; a sensor; a cap; a cap shifter; a reference wall; a memory; a power supply; a command receiver; and a controller. The controller is configured to execute judging a state of the power supply section; changing a relative position of the recording head and the cap from the covering position to the separated position to take the cap off the recording head; switching the power supply from the sleep state to the drive state, changing a relative position of the recording head and the cap from the covering position to the separated position by taking the cap off the recording head, storing in the memory the position information, and recording an image on the sheet conveyed to the sheet facing area.

A liquid discharge head is configured to achieve decrease in temperature difference in the liquid discharge head, and includes a recording device including the liquid discharge head. The liquid discharge head includes a channel member having a plurality of discharge holes, a plurality of pressurization chambers, and a plurality of common channels, and a plurality of pressurizing parts. The plurality of common channels extends in a first direction and configures a common channel group aligned in a second direction crossing the first direction, the common channels are connected with the plurality of pressurization chambers disposed along the common channels among the plurality of pressurization chambers, and the channel member is disposed outside, in the second direction, with respect to the common channel group, and further includes a first end channel extending in the first direction, and the first end channel is lower in channel resistance than the common channels.

A method of wiping an inkjet printhead. The method includes the steps of: lifting a print module carrier relative to a media feed path, the print module carrier having a mounting arm bridging over a wiper carriage parked at one longitudinal end of a printhead carried by the print module carrier; and moving the wiper carriage, from its parked position below the mounting arm, longitudinally along the printhead to wipe a surface of the printhead.

A print pen capping apparatus for a printer comprises a cap station carrying one or more caps, wherein the cap station is moveable between a retracted position in which the cap station is arranged at a side of a print media path and a capping position adjacent the media path for capping the print pen.

A controller of an inkjet printing apparatus is configured to receive first data, which an information processing apparatus transmits in response to receipt of a print instruction. The first data includes an instruction to move the cap from a covering position to a spaced position. Upon receipt of the first data, the controller determines a location of the cap. Then, upon determination that the cap is located at the spaced position, the controller determines the state of the driving force transmission assembly. The controller switches the state to the first state by moving the carriage to the non-recordation area in response to determination that the state is not the first state. Then, the controller receives second data, which includes image recordation condition, from the information processing apparatus, in response to determination that the state is the first state or after switching of the state to the first state is started.

There is provided a liquid discharge apparatus including a discharge head including nozzles and actuators; a liquid detecting sensor; and a controller. The controller is configured to: cause the actuators to perform a discharge operation; calculate a discharge amount of the liquid discharged from each of the nozzles; determine the discharge amount of the liquid; and cause a first actuator corresponding to a first nozzle, whose discharge amount is less than a first predetermined amount, and a second actuator corresponding to a second nozzle, whose discharge amount is not less than the first predetermined amount and less than a second predetermined amount, to perform a flushing, without causing a third actuator corresponding to a third nozzle, whose discharge amount is not less than the second predetermined amount, to perform the flushing.

A print device includes a head, a cap, a suction portion, an absorption member, and a plate-shaped member. The head has an ejection surface. The ejection surface has a plurality of nozzles formed in the ejection surface and is directed in a predetermined direction. The cap has a frame-shaped wall portion and a suction opening. The suction portion is connected to the inside of the cap via the suction opening. The absorption member is arranged in a position surrounded by the frame-shaped wall portion and is configured to absorb liquid. The plate-shaped member is surrounded by the frame-shaped wall portion and is arranged in a position facing the absorption member. The plate-shaped member is extending along an inner end surface of the frame-shaped wall portion and has a hole.
