An aerosol-based printing apparatus is provided capable of producing an aerosol stream at a constant rate and constant material deposition to a substrate to provide high-definition, high-resolution traces. The aerosol-based printing apparatus provides production, transport, and delivery of an aerosol stream at a constant rate for a period of time of at least 8 hours and other instances more than 24 continuous hours of constant operation. By inhibiting bulging and necking of the deposited trace, superior line width tolerances are achieved, and such tolerances are maintained for extended periods of time, thereby allowing for both the deposition of complex traces as well as consistent manufacture of duplicate articles that maintain the tolerances across a production ran. The accumulation of fluids in the aerosol and gas transport conduits are eliminated, thereby eliminating the need for purge or cleaning cycles and allowing for uninterrupted operation for a minimum of 24 hours.

A printing apparatus includes a support member having a bearing portion, and includes a locking member including a shaft portion fitted to the bearing portion and a biasing member arranged to bias the support member and the locking member in a first direction. The support member supports a printing member that prints on a printing medium. The locking member is pivotally mounted to the support member. The shaft portion is a pivot center. The locking member fixedly holds the printing member relative to the support member. The first direction forms an angle from 0 degree to smaller than 45 degrees relative to an upper surface of the printing member in a first state in which the printing member is fixedly held relative to the support member by the locking member. Movement of the shaft portion fitted to the bearing portion in the first direction is restricted by the biasing member.

An image forming system includes an image forming apparatus having an image forming unit and a supplier having a first supply port though which a first consumable item is supplied to a first accommodating portion and a second supply port through which a second consumable item is supplied to a second accommodating portion, and a guide. The image forming system further includes a first bottle including a first connector having a first outlet port connectable to the supplier and a first guided portion configured to be guided by the guide in a state in which the first connector is attached to the supplier, and a second bottle including a second connector having a second outlet port connectable to the supplier and a second guided portion configured to be guided by the guide in a state in which the second connector is attached to the supplier.

An ejection-material ejection apparatus and an imprinting apparatus are provided which are capable of quickly detecting damage of a flexible membrane and avoiding contact between an ejection material and an operating liquid even if part of the flexible membrane is damaged. The flexible membrane includes a first film (1) covering a first storing space (5) for the ejection material, a second film (2) covering a second storing space (6) for the operating liquid, and an inter-film space 4 situated between the first film (1) and the second film (2). A change in state of the inter-film space (4) resulting from communication between at least one of the first storing space (5) and the second storing space (6) and the inter-film space (4) is detected with a liquid sensor (41), a flow speed sensor (77), and a liquid leakage sensor (42).

In a board that includes a plurality of contact portions that are arranged to contact corresponding apparatus-side terminals when the board is mounted in a printing apparatus, some contact portions are disposed in a first region, and the remaining contact portions are disposed in a second region. The some contact portions include a first contact portion, a second contact portion, a third contact portion, and a fourth contact portion. The remaining contact portions include a fifth contact portion. The some contact portions are arranged in a first pattern in the first region and the remaining contact portions are arranged in a second pattern in the second region, and the first pattern is asymmetrical to the second pattern with respect to a first virtual line.

A fluid cartridge and a method for eliminating mechanical stresses on an ejection head chip. The fluid cartridge includes a plastic fluid body having a front wall, a rear wall opposite the front wall, left and right side walls attached to the front wall and to the rear wall, a bottom wall attached to the front wall and the rear wall, and to the left and right side walls. A die bond member is attached to the plastic fluid body adjacent to the bottom wall and an ejection head chip is disposed on the die bond member so that the die bond member is between the bottom wall and the ejection head chip.

A tank includes: a tank body defining a storage chamber; a recessed portion provided at the tank body; a slider positioned in the recessed portion; a fitting portion provided at the slider; and a sealing member. The recessed portion has an injection opening in communication with the storage chamber, and a connection opening through which a liquid container is connectable. The slider includes a nozzle extending toward the connection opening in an extending direction and having a communication opening communicable with the injection opening. The slider is movable toward and away from the connection opening in the extending direction while rotating relative to the recessed portion. The fitting portion can be fitted with the liquid container. The sealing member can provide a liquid tight sealing to a gap between the slider and the recessed portion, and allow liquid flow between the communication opening and the injection opening.

The printing apparatus of the present invention includes: a print head; and a liquid storage container in which a liquid storage chamber that stores a liquid to be supplied to the print head, an atmosphere communication chamber that communicates with the atmosphere, and a communication flow path that causes the liquid storage chamber and the atmosphere communication chamber to communicate are formed integrally. The liquid storage container can take a first posture in which the atmosphere communication chamber is located under the liquid storage chamber in the direction of gravity and a second posture in which the atmosphere communication chamber and the liquid storage chamber are located side by side in the horizontal direction. In the case where the liquid storage container is in the second posture, the liquid injection portion and the communication flow path are located on the upper side of the liquid storage container.

A printing-fluid cartridge is inserted into a printing-fluid consuming apparatus in an insertion direction crossing a gravitational direction and attached thereto in a first posture. The printing-fluid cartridge includes: a storage chamber, a supply portion having a supply port, an upper surface and a locking surface positioned upward of the storage chamber, an electrical interface disposed at the upper surface, and a contact surface positioned rearward relative to the supply port of the supply portion in the insertion direction in the first posture. The printing-fluid cartridge inserted in the printing-fluid consuming apparatus is movable between the first posture and a second posture. In the first posture, the locking surface engages a lock portion and the contact surface abuts against a positioning portion. In the second posture, the locking surface is positioned downward relative to the lock portion and the contact surface is separated from the positioning portion.

A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid and an attachment portion to which a liquid container that stores the liquid supplied to the liquid ejecting head is detachably attached. The attachment portion includes a liquid inlet portion that is coupled to a liquid outlet provided in the liquid container, and an urging mechanism that urges the liquid container in a direction opposite to an attaching direction in which the liquid container is attached to the attachment portion. The urging mechanism includes an elastic member that is in close contact with the liquid container attached to the attachment portion and that is provided below the liquid inlet portion in a direction of gravity.
