A recording portion has a nozzle surface. A first movement portion moves the recording portion in a first direction intersecting the nozzle surface. A second movement portion moves a first maintenance portion in a second direction along the nozzle surface. The recording portion is movable to a recording position at which recording is performed on a medium, and a first retreated position where the recording portion is retreated from the recording position. The first maintenance portion is movable to a maintenance position at which maintenance of the nozzle surface is performed and a second retreated position retreated from the maintenance position. When an error occurs, a control portion causes the recording portion to retreat away from the first maintenance portion in a first direction. Then, the first maintenance portion is caused to retreat in a second direction.

A supporting section is disposed to confront an ejection surface and supports a recording medium. A first tank is mounted on a first-tank mount section. A liquid conveying section conveys liquid to a liquid ejecting head. A receiving section receives liquid ejected from the liquid ejecting head. A waste-liquid conveying section conveys liquid to the waste-liquid tank. A first casing holds the liquid ejecting head, the first-tank mount section, and the liquid conveying section. A second casing holds the supporting section, the receiving section, the waste-liquid tank, and the waste-liquid conveying section. The first casing is connected with the second casing such that the first casing is movable relative to the second casing. The first casing takes a first position at which the ejection surface confronts the supporting section and a second position at which the ejection surface is farther away from the supporting section than at the first position.

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.

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.

An image forming apparatus for forming an image with a coloring material on a recording medium includes a region specifier that specifies a region that becomes a margin when the image is formed on the recording medium; and a pattern image generator that generates image data of a pattern image to be formed in the region based on a size of the region and a type of the coloring material.

A nozzle surface wiping device capable of using a plurality of types of wiping members in a state where discharge deterioration is suppressed regarding the respective wiping members is provided. In the nozzle surface wiping device that wipes a nozzle surface of a liquid discharge head with a wiping member to which a cleaning liquid is applied, information on cleaning liquid application conditions for applying respective saturated liquid amounts of the cleaning liquid to a plurality of types of wiping members, respectively, according to the types of the respective wiping members is held in advance. The type of a wiping member to be used for the wiping of the nozzle surface of the liquid discharge head is specified, and a saturated liquid amount of the cleaning liquid is applied to the wiping member according to the determined cleaning liquid application conditions corresponding to the type of the specified wiping member.

A droplet discharging apparatus includes a recording head that includes pressure chambers, piezoelectric elements, and an in-head reservoir, provided near the pressure chambers; a liquid circulation unit that includes a liquid reservoir and circulates liquid between the in-head reservoir and the liquid reservoir; a drive waveform generation unit that generates a drive waveform that drives each of the piezoelectric elements; a remaining oscillation detection unit that detects remaining oscillation generated in at least one of the pressure chambers after driving the respective piezoelectric element; a status determining unit that determines a sedimentation status of a component in liquid in the in-head reservoir based on the detected remaining oscillation; and a control unit that controls a liquid circulation operation of the liquid circulation unit in order to dissolve the sedimentation status of the component in the liquid in the in-head reservoir based on the determined sedimentation status.

A method of wiping a plurality of printheads positioned in a staggered overlapping arrangement across a width of a media feed path, each printhead having a respective wiper associated therewith. The wipers for neighboring printheads are moved in opposite directions with respect to each other.

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.
