A transport device including a transporting belt that includes a medium-supportable outer circumferential surface and transports the medium, a cleaning roller capable of cleaning the outer circumferential surface, a storage unit that stores a cleaning liquid supplied to the outer circumferential surface via the cleaning roller, a discharge port through which the cleaning liquid is dischargeable, a flow path pipe through which the discharged cleaning liquid is passable, a pump that changes an internal pressure of the flow path pipe to cause the cleaning liquid to flow so that the cleaning liquid stored in the storage unit is discharged from the storage unit through the discharge port and the flow path pipe, a sensor capable of detecting the internal pressure of the flow path pipe, and a control unit that determines a state of the cleaning liquid stored in the storage unit based on a detection result of the sensor.

Transport device and liquid ejecting apparatus

A liquid ejecting apparatus which includes a carriage including an ejecting unit which ejects liquid onto a medium, and can move in a reciprocating direction, in which the carriage includes catching units which catch mist which occurs along with ejecting of the liquid from the ejecting unit on at least one side of the ejecting unit in the reciprocating direction, and the catching units include a fan which moves the mist from the catching units by generating an air current.

Liquid ejecting apparatus

A liquid ejecting apparatus which includes an ejecting unit which ejects liquid, and a collecting unit which collects mist which occurs along with ejecting of the liquid from the ejecting unit from a collecting port, in which the collecting unit includes a backflow prevention unit in the collecting port. By adopting such a liquid ejecting apparatus, it is possible to suppress backflow of mist of the liquid from the collecting unit which collects mist of the liquid which occurs along with ejecting of liquid from the ejecting unit.

A liquid ejecting apparatus which includes a carriage which can move in a reciprocating direction, in which the carriage is provided with an ejecting unit which ejects liquid, a circuit board which inputs a signal to the ejecting unit, and a fan which can blow air toward the circuit board, and includes a separator which separates a path through which mist which occurs along with ejecting of liquid from the ejecting unit reaches the fan.

A liquid discharging apparatus includes multiple nozzle rows, in which a plurality of nozzles capable of discharging liquid onto a medium are arranged, that are arranged in an intersection direction intersecting with a nozzles-arranged direction where the nozzles are arranged, a shielding portion that shields an area between the nozzle rows, and a collecting portion that collects mist which is attached to the shielding portion and is generated due to discharging of the liquid from the nozzles.

Liquid discharging apparatus

Provided is a liquid ejecting apparatus including: a liquid ejecting head that ejects liquid from nozzle openings by driving of an ejection driving portion; a driving signal generation portion that generates a driving pulse for driving the ejection driving portion; a liquid receiving portion that is disposed so as to oppose a nozzle forming face of the liquid ejecting head and receive ink ejected from the nozzle openings; and an ejection inspecting portion that detects an electrical variation occurring between a conductive portion of the liquid ejecting head and the liquid receiving portion when liquid is ejected toward the liquid receiving portion from the nozzle openings in a state where an electric voltage is applied between the conductive portion and the liquid receiving portion, thereby inspecting whether or not liquid has been ejected from the nozzle openings. The driving signal generation portion generates a normal driving pulse which is used for processes other than an ejection inspection process by the ejection inspecting portion and an ejection inspection driving pulse which is different from the normal driving pulse and is used for the ejection inspection process by the ejection inspecting portion.
