A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

A sheet conveyor includes a conveyance belt configured to rotate to convey a sheet on which a liquid has been applied in a conveyance direction, and a guide configured to guide the sheet to the conveyance belt, a position of the guide being variable in the conveyance direction.

A print head assembled to a liquid ejecting apparatus ejecting a liquid with respect to a medium includes an ejecting portion ejecting the liquid in response to a drive signal and an electrically erasable non-volatile memory, and the non-volatile memory stores history information changing in accordance with an operation state of the print head.

A liquid ejecting device performing printing by ejecting liquid onto a medium in a printing region, the liquid ejecting device including an ejecting unit including a first ejecting unit ejecting the liquid onto the medium, and a second ejecting unit ejecting a reaction liquid containing a coagulant for coagulating a component in the liquid, a transport unit configured to transport the medium, a jam detector configured to detect a jam of the medium, and a control unit configured to control the ejecting unit, and the transport unit, wherein when the jam is detected in the jam detector, the control unit causes the transportation of the medium by the transport unit to stop, and causes the liquid, the reaction liquid, or the liquid and the reaction liquid to be ejected in the printing region from the first ejecting unit, and the second ejecting unit.

A sheet conveying apparatus, includes: a first roller; an opening-closing member that is movable between an open position and a close position; a second roller; an urging member; a restraint member switching between a restraint state in which a rotation shaft of the second roller is restrained and a release state in which the rotation shaft is released from the restraint, by being moved, wherein, during the movement of the opening-closing member from the open position to the close position, the restraint member keeps the rotation shaft in the restraint state; and a releasing member that is moved by driving force from the drive source when the opening-closing member is in the close position and the rotation shaft is in the restraint state, the releasing member switching the rotation shaft to the release state by moving the restraint member as being engaged with the restraint member.

An image forming apparatus includes a connector, a conveyance unit, and a controller. The conveyance unit includes first and second sensors, first and second light sources, and a capacitor. Based on the first and second sensors, the controller determines a position of a paper jam having occurred during an image formation job. The first light source is turned-on when the position of the paper jam corresponds to a position of the first sensor and the second light source is turned-on when the position of the paper jam corresponds to a position of the second sensor. When the conveyance unit is pulled out of the image forming apparatus, the connector shuts off the electrical connection between the conveyance unit and a power source, and a light source controlled to turn on by the controller glows based on electric power accumulated in the capacitor during the image formation job.

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.

An upper supply tray is mounted at an upper mount position in a housing. A lower supply tray is mounted at a lower mount position lower than the upper mount position in the housing. A first print engine records an image on a sheet conveyed from the upper supply tray. A second print engine records an image on a sheet conveyed from the lower supply tray. A lower discharge tray supports the sheet on which the image is recorded by the first print engine. An upper discharge tray supports the sheet on which the image is recorded by the second print engine. The upper discharge tray is located at a higher position than the lower discharge tray. A first display displays at least: a first correspondence between the lower discharge tray and the upper supply tray; or a second correspondence between the upper discharge tray and the lower supply tray.

Provided are a carriage structure capable of preventing a carriage from contacting a side edge of a print medium, without requiring a discharge roller and facilitating reducing device size, and a printer having the carriage structure. Disposed to a carriage 21 carrying and inkjet head 22 and moving bidirectionally through a range of movement including the conveyance path of a cut-sheet paper S are: a panel member 78 able to protrude in the direction of carriage 21 movement; and a moving mechanism 126 causing the panel member 78 to protrude to the conveyance path of the cut-sheet paper S when the carriage 21 is at a standby position (home position) set in the range of carriage 21 movement.

A printer can suppress paper lifting away from the platen surface even when conveying strong paper (regardless of paper strength) (a printer that can suppress paper uplift from the platen and is not easily affected by the type of paper). A printer 40 in which the platen surface 42a is on the inkjet head 21 side of a plane C through position A where paper 11 is held by a conveyance roller 36, and position B where the paper is held by a discharge roller, has: on the printhead 21 side of the plane C between the platen 42 and conveyance roller 36, at least one entry angle control unit 44 that contacts the paper 11 conveyed toward the platen surface 42a, and controls the entry angle of the paper 11 to the platen surface 42a; and on the printhead 21 side of the plane C between the platen 42 and the discharge roller 37, at least one exit angle control unit 46 that contacts the paper 11 conveyed in the direction away from the platen surface 42a, and controls the exit angle of the paper 11 from the platen surface 42a.
