A liquid jetting apparatus includes: a casing; a tank configured to store liquid and having a first side wall and a second side wall which face each other, a rear wall, an inlet, and a connecting portion; a conveying mechanism configured to convey a recording medium along a conveying path extending in a first direction; a carriage configured to move in a second direction in which the first side wall and the second side wall face each other so as to define a movement area having a range in the second direction, the range of the movement area having first and second ends spaced apart in the second direction; a tube connected to the connecting portion; and a head mounted on the carriage and having a nozzle configured to jet the liquid onto the recording medium conveyed by the conveying mechanism.

Liquid jetting apparatus

A liquid jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction.

A printer controls a suction pump such that a difference in a discharge amount of an ink and a flow speed of the ink discharged from each nozzle is small between a complete purge in which all ink supply portions connected to a second head communicate with an atmosphere, and a suction purge is performed simultaneously for the nozzles of all types of the second head, and a partial purge in which a communication of a part of the ink supply portions with the atmosphere is blocked by a dummy cartridge, and the suction purge is performed only for the nozzles corresponding to the ink supply portions of which the communication with the atmosphere is not blocked.

Liquid droplet jetting apparatus

A recording apparatus has a cartridge installing section including a case which is formed with an opening and which is configured to receive printing fluid cartridges respectively via the opening; a flat plate-shaped lid which has a rotational shaft and which undergoes posture change to a closed posture and an open posture by being rotated around the rotational shaft. The lid has a curved section which is disposed on a side of one end in a widthwise direction along the rotational shaft and which is curved so that the one end is directed to a side of the ending surface of the case in a state in which the lid is in the closed posture; and the curved section is upstanding upwardly from a side of a bottom surface of the case in a state in which the lid is in the open posture.

Recording apparatus and printing fluid cartridge set

An inkjet printer is provided. The inkjet printer includes: an inkjet head which ejects ink toward a surface of a recording medium; a platen provided opposed to the inkjet head to support the recording medium from an opposite side of the inkjet head; and an absorber provided opposed to the inkjet head at the same side as the platen with respect to the recording medium supported by the platen. The absorber includes a plurality of regions different in absorption rate from one another in a plan view observed from a normal direction of the recording medium supported by the platen.

Inkjet printer

A set of cartridges includes a first cartridge including a first tank, wherein a liquid level in the first tank is at a first position when an amount of liquid stored in the first tank is a predetermined amount, and a second cartridge including a second tank, wherein a liquid level in the second tank is at a second position which is below the first position when an amount of liquid stored in the second tank is the predetermined amount. The first cartridge is configured such that a light-blocking portion moves out of a detection region when the liquid level in the first tank lowers and reaches the first position, and the second cartridge is configured such that a light-blocking portion moves out of the detection region when the liquid level in the second tank lowers and reaches the second position.

Set of cartridges and printer

A liquid ejecting apparatus includes a detector configured to be in a first state when an amount of liquid stored in a liquid container is greater than a first threshold amount, and to be in a second state when the amount of liquid is less than or equal to the first threshold amount, an estimator configured to estimate the amount of liquid, and a determiner configured to determine that, if it is determined that the state of the detector has changed from the first state to the second state, the liquid container has become a low-amount state, and that, if it is determined that the amount of liquid estimated by the estimator has become less than or equal to the second threshold amount, which is less than the first threshold amount, the liquid container has become the low-amount state.

Liquid ejecting apparatus

If any change, which appears on a display for displaying the situation of the operation, is detected, it is judged whether or not an elapsed time, which elapses from the previous execution of the restoring operation for the discharge state of nozzles, exceeds a predetermined time period. If the elapsed time exceeds the predetermined time period, the control is made by a controller so that the restoring operation is executed for the recording head. The restoring operation is executed before the instruction of the recording operation for a recording medium in a multi function device which has various functions including, for example, the copy function, the facsimile function, the scanner function, and the printer function in combination and which is provided with the functions in a multifunctional manner. Therefore, the waiting time for a user, which is required until the completion of the recording, can be shortened.

Image recording apparatus and method for restoring recording head for image recording apparatus

A liquid container includes a liquid chamber configured to store liquid, and a float positioned in the liquid chamber and configured to move according to a change in a level of a liquid surface in the liquid chamber. The float includes a liquid-retaining portion configured to retain liquid therein, and at least a portion of the liquid-retaining portion is positioned above the liquid surface when a portion of the float is positioned above the liquid surface.

Liquid containers

A liquid supply device includes a liquid cartridge, which has a liquid chamber that stores liquid, a cartridge mounting portion, and a surface detector. The liquid chamber has a first portion, a second portion, and a third portion. The liquid cartridge removably attaches to the cartridge mounting portion. The surface detector detects a surface of the liquid stored in the liquid chamber. A horizontal cross-sectional area of the first portion of the liquid chamber is less than each of a horizontal cross-sectional area of the second portion and the third portion of the liquid chamber, and the first portion of the liquid chamber is positioned between the second portion and the third portion of the liquid chamber in a direction orthogonal to the horizontal cross-sectional area of the first portion of the liquid chamber.
