A printing apparatus (200) includes a slot (230) to and from which a memory unit (100) storing permitted usage amount information can be attached and removed, and a processing unit (210) that carries out a process for updating estimated ink amount information. The processing unit (210) carries out a charging process using a first memory unit (100-1), and in the case where a second memory unit (100-2) has been attached to the slot (230) after the charging process, the processing unit (210) does not carry out a charging process using the second memory unit (100-2) until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit (210) carries out the charging process using the second memory unit (100-2) in the case where the consumed ink amount has exceeded the prescribed threshold (WTH).

An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

A printing apparatus on which an ink tank containing ink to be used for printing is mounted, the printing apparatus including: a cover configured to be opened in a case where the ink tank is replaced; an operation unit configured for shifting to a replacement state in which the ink tank can be replaced; and a control unit configured to display a screen for guidance of a user operation for shifting the ink tank to the replacement state on a display unit if the cover is opened in a case where the ink tank can be replaced and shift the ink tank to the replacement state in a case where the operation unit is operated in a state where the screen is displayed on the display unit.

A liquid discharge cartridge manufacturing method includes a first step of individually shaping a first shaped member and a second shaped member that form a housing of a liquid discharge cartridge, and a second step of joining the first shaped member and the second shaped member to be bonded to each other with molten resin. The first step includes shaping a wall section in the first shaped member, the wall section forming a recess for accommodating the molten resin, and shaping a projection in the second shaped member, the projection extending such that the projection is located at the outer side of the wall section and adjacent to the wall section, with a predetermined gap being formed between the projection and the wall section, when the first and second shaped members are joined.

A fluid fillable cartridge, a method for preventing contamination of nozzle holes in a fluid ejector chip and a method for making an adhesive sealing tape. The fluid fillable cartridge has an open fluid reservoir therein and a fluid ejector chip attached to an exposed surface of the fluid fillable cartridge opposite to the open fluid reservoir. An adhesive sealing tape is attached to the fluid fillable cartridge, wherein the adhesive sealing tape has an adhesive pattern on a first end of the adhesive sealing tape that is configured to attach the adhesive sealing tape adjacent to the fluid ejector chip while being devoid of adhesive in nozzle hole areas of the fluid ejector chip.

An image-recording apparatus includes: a first tank defining a first storage chamber; a second tank defining a second storage chamber; a conveying mechanism for conveying sheets along a conveying path extending in a depthwise direction and a widthwise direction perpendicular to a vertical direction and the depthwise direction; and a recording head including a nozzle. Liquid in the first storage chamber is supplied through a communication port to the second storage chamber and then to the recording head through a liquid outlet port. The second storage chamber is positioned further in a first depthwise direction relative to the nozzle and further in a first widthwise direction relative to the conveying path. A volume of a prescribed space above a liquid level equal to a height of the communication port in the second storage chamber is greater than that of a liquid channel between the liquid outlet port and the nozzle.

A tank includes: a wall separating a liquid storage chamber, which stores a liquid to be supplied to a liquid consuming part, from an outside; an inlet penetrating the wall; and a liquid outflow part which allows the liquid to flow to the outside of the liquid storage chamber. The wall includes a view wall, which extends upward and downward and allows a user to visually check a liquid level in the liquid storage chamber, and a bottom wall, which defines an inner bottom surface of the liquid storage chamber by being connected to the view wall. The inner bottom surface of the bottom wall includes an inclined part which extends from at least a part of the view wall to incline downward in a direction away from the view wall.

It is disclosed a printing agent container receptacle that can receive printing agent containers of different sizes. The printing agent container receptacle comprising an actuator that, upon receipt of a longitudinal insertion force on the container defines a stop position of the printing agent container.

A communication method according to an embodiment of the present invention is performed between a communication device and an electrical apparatus by use of non-contact short-range wireless communication method. The electrical apparatus includes a built-in antenna in the vicinity of a first region of a surface exposed to the outside of the electrical apparatus. The antenna is provided for non-contact short-range wireless communication with the communication device. The communication method includes the steps of: preparing a storage box to which information is provided at a predetermined position on an exterior surface of the storage box, the information indicating where the antenna is placed; storing the electrical apparatus in power-off state, into the storage box, and thereby placing the electrical apparatus in the storage box such that the first region of the electrical apparatus is close to the predetermined position of the storage box; and moving the communication device close to the predetermined position of the storage box to initiate communication between the communication device and the electrical apparatus.

There are included a packing material that has a moisture-proof property and forms a third space, a liquid ejecting head that includes a case member which forms a second space communicating with the third space, and a first moisture absorbing material and a piezoelectric element which are disposed in the second space, and is disposed in the third space, and a second moisture absorbing material that has a higher moisture absorbing property than that of the first moisture absorbing material and is disposed in the third space.
