A memory stores manufacturing information including at least the number of refills, an electronic signature of the manufacturing information, and a first error-detecting code of the manufacturing information. The number of refills is the number of times that, after consumption of a liquid contained in the cartridge, the cartridge is refilled with the liquid.

Described herein are bioprinters comprising: one or more printer heads, wherein a printer head comprises a means for receiving and holding at least one cartridge, and wherein said cartridge comprises contents selected from one or more of: bio-ink and support material; a means for calibrating the position of at least one cartridge; and a means for dispensing the contents of at least one cartridge. Further described herein are methods for fabricating a tissue construct, comprising: a computer module receiving input of a visual representation of a desired tissue construct; a computer module generating a series of commands, wherein the commands are based on the visual representation and are readable by a bioprinter; a computer module providing the series of commands to a bioprinter; and the bioprinter depositing bio-ink and support material according to the commands to form a construct with a defined geometry.

A liquid supplying device includes a tank a tank and a cartridge. The cartridge includes a first storage chamber. The cartridge is formed with a communicating opening in communication with the first storage chamber. The tank has a second storage chamber and a joint having a hollow cylindrical shape. In an attachment state where the communicating opening of the cartridge is connected to the joint, the first storage chamber has a portion positioned above the joint and the second storage chamber is positioned below the joint. At least in the first end portion, the liquid passage has a rectangular shape in a cross section taken along a plane perpendicular to an extending direction of the liquid passage.

Disclosed are an apparatus and a method for quickly and accurately inspecting a droplet on a substrate. An apparatus for inspecting a droplet on a substrate according to an exemplary embodiment of the present disclosure includes: an ultrasonic sensor configured to apply an ultrasonic wave to a droplet on the substrate and detect an ultrasonic wave reflected from the substrate; and a processor configured to acquire a height of the droplet at each position on the substrate on the basis of a signal of the ultrasonic wave reflected from the droplet on the substrate, calculate a volume of the droplet on the basis of the heights of the droplet at the positions, and store or output data in relation to the volume of the droplet. The embodiment of the present disclosure may calculate the volume of the droplet using the ultrasonic wave, thereby quickly and accurately inspecting the droplet on the substrate.

Liquid supply system for an analyzer. Liquid supply system includes a liquid-containing container and a spout support tool. Liquid-containing container is made up of a rectangular parallelepiped box comprising a wall with an opening therein, and a collapsible insert including a liquid-containing portion received inside the rectangular parallelepiped box. The collapsible insert includes a spout with a flange wherein both are retractable through the opening. The support tool has a body having an engaging portion and a grasping portion, the engaging portion includes a first engagement surface engaged with a surface of the wall, a second engagement surface, and a spout receiver formed in the engaging portion that is configured to be received under the flange to support the spout. pout support tools and retaining methods of a liquid supply system are provided, as are other aspects.

A liquid container is removably mountable into the apparatus body of a liquid ejection apparatus. The liquid container comprises a liquid storage chamber equipped with an air intake hole and a liquid supply port, for storing liquid and a valve unit having a sealing member and an urging member. The urging member is arranged so as to be at least partly rotationally movable and the urging member has urging force for urging the sealing member in the direction of making the sealing member abut the air intake hole. The sealing member is rotationally movable between a position of abutting and closing the air intake hole and a position separated from the air intake hole so as to open the air intake hole in response to a rotary motion of the urging member.

In one embodiment a print liquid supply apparatus is provided to supply liquid to a liquid needle of a receiving station comprising a liquid container including an at least partially collapsible liquid reservoir an interface structure at a side of the container, including a liquid channel that includes a reservoir connecting portion that fluidically connects to the reservoir and a needle receiving portion to allow the liquid to flow from the reservoir to the needle; a liquid interface of the liquid channel adjacent the needle receiving portion and at a distance from the reservoir connecting portion, a front wall and/or edge adjacent the liquid interface including a push area which is disposed between the liquid interface and the container; and at least one key pen base and key pen protruding from the base in a direction parallel and opposite to the needle insertion direction; and a contact pad array next to the needle receiving liquid channel portion. In another example a sub-assembly of such apparatus is provided.

A liquid cartridge is configured to be inserted into a liquid consuming apparatus in a first direction along a horizontal direction against an urging force directed in a second direction opposite the first direction, and thereby to be mounted to the liquid consuming apparatus. The liquid cartridge is configured to pivot about a pivot center in the liquid consuming apparatus. The liquid cartridge includes a rear face, and the rear face includes a first portion and a second portion positioned further in an upward direction than the first portion. The first portion includes a portion positioned further in a downward direction than the pivot center, and the first portion is positioned further in the first direction than the second portion.

A printing-fluid containing device configured to be inserted into a cartridge attachment section in an insertion direction includes: a printing-fluid cartridge and an adaptor to which the cartridge is detachably assembled. The cartridge includes: a casing; a supply portion; a detection portion; and an engagement portion. The adaptor includes: an adaptor body; and an electrical interface. The detection portion includes a light accessible portion accessed by light from an outside of the cartridge. The engagement portion is engageable with the cartridge attachment section. The adaptor body has a front wall at its leading end in the insertion direction. The front wall has an opening through which the supply portion extends.
