摘要： A cleaning liquid supplying apparatus includes a first reservoir unit, a second reservoir unit of a pressure accumulation type, a supply flow path, a pump, a return flow path, a flow path valve, an atmospheric relief valve, a control unit, a plurality of cleaning liquid ejecting units, a pressure detection unit, and a determination unit. The first reservoir unit is provided at a position lower than a position of the second reservoir unit in the gravity direction, and when the determination unit determines that an amount of air is abnormal, after the cleaning liquid stored in the second reservoir unit is discharged to the first reservoir unit until a liquid level of the cleaning liquid stored in the second reservoir unit reaches a reference liquid level, the control unit causes the cleaning liquid to be delivered from the first reservoir unit to the second reservoir unit again.

摘要： A transporting belt constituting a transport device transports a medium supported by a front surface in a transport direction. A removal unit includes a blade that comes into contact with the front surface to remove an adhering substance. A plurality of detectors detect a force received by the blade from the transporting belt or a change in the force. A display unit displays information. An adjustment unit is configured to adjust a position of the blade relative to the transporting belt. Each of the detectors are provided corresponding to a respective one of a plurality of regions into which the transporting belt is divided in the width direction intersecting the transport direction. When the control unit determines that there is an abnormal region among the regions based on detection results of the detectors, the control unit causes the display unit to display information indicating the abnormal region.

摘要： A transport device includes a transport belt, an abutting unit, a moving mechanism, and a displacement detection unit. The transport belt has an adhesive layer capable of adhering to a medium, and is capable of transporting the medium adhering to the adhesive layer. The abutting unit is capable of abutting against a surface of the adhesive layer. It is assumed that a direction in which the abutting unit is away from the adhesive layer is a first direction and a direction opposite thereto is a second direction. The moving mechanism is capable of moving a position of the abutting unit with respect to the surface in the first direction and the second direction. The displacement detection unit detects a displacement amount of the transport belt in the first direction when the moving mechanism moves the abutting unit in the first direction while the abutting unit abuts against the surface.

摘要： A liquid ejecting apparatus includes: a pump which is provided for a liquid supply path to supply a liquid stored in a liquid storage portion to a liquid ejection portion; a filter portion which is provided between the pump and the liquid ejection portion as a part of the liquid supply path and which includes a filter and a filter chamber defined by the filter into an upstream filter chamber and a downstream filter chamber; a return path coupled to the upstream filter chamber and the liquid storage portion; and a discharge valve located at the return path. While the pump is driven in a non-communication state between the upstream filter chamber and the liquid storage portion, the non-communication state is switched to a communication state therebetween through the return path using the discharge valve.

摘要： A liquid ejection device includes a head, a medium supporting section and a first member. The head has a nozzle configured to eject a liquid onto a recording medium. The head is configured to move in a head travel direction. The medium supporting section is configured to support the recording medium. The first member has a curving face. The first member is disposed in a position overlapping the head travel direction and not overlapping the medium supporting section and the recording medium supported on the medium supporting section in a plan view. The first member is arranged so that the curving face faces a nozzle face of the head on which the nozzle is formed when the first member faces the head. The head is further configured to eject the liquid onto the curving face of the first member when the head faces the first member.
