In an image-recording device, a cartridge has a first chamber and an outlet. A mount body includes a tank, first and second sensors. The tank has an inlet, and a second chamber. The liquid in the first chamber flows into the second chamber via the outlet and the inlet. The first sensor outputs a first signal when a level of the liquid in the second chamber is higher than a first position, and outputs a second signal when the level is lower than the first position. The second sensor outputs a third signal when the level is higher than a second position higher than the first position, and outputs the fourth signal when the level is lower than the second position. A controller controls a notification device to issue a notification if a condition based on the first and second signals is satisfied.

A cartridge includes a liquid containing portion and a liquid supply portion that includes a cartridge side valve mechanism, the cartridge side valve mechanism includes a cartridge side valve seat in which a cartridge side valve hole is formed, a cartridge side valve body that stops the cartridge side valve hole and has a tip surface positioned adjacent to the supply opening, and a cartridge side urging member that urges the cartridge side valve body in a direction toward the cartridge side valve seat, and the cartridge side valve body has a protrusion that protrudes from the tip surface and pushes the device side valve body to open the device side valve body.

A cartridge detachably mounted in a liquid ejecting apparatus including a liquid introduction portion includes: a liquid supply portion having a supply portion flow path; a valve seat having a valve seat insertion port; a valve body upstream of the valve seat; a biasing member biasing the valve body toward the valve seat; a cap located downstream of the valve seat; and a liquid absorbing material in contact with the cap, in which the cap has a first surface facing the valve seat, a second surface facing the first surface and contacting the liquid absorbing material, a cap insertion port formed over the first and second surfaces, into which the liquid introduction portion is inserted, a groove formed in the first surface and facing the valve seat, and a hole formed over the first and second surfaces and coupled to the groove, and liquid absorbing material is in the hole.

A cartridge includes: a liquid accommodating portion; a liquid supply portion having a central axis and a supply portion flow path which communicates with the liquid accommodating portion; and a valve mechanism arranged in supply portion flow path, wherein the valve mechanism has a valve seat having an insertion port into which liquid introduction portion is inserted, a valve body having a closing surface which abuts on the valve seat to close the insertion port, and a biasing member biasing valve body toward the valve seat, the valve mechanism is opened by the valve body being pushed by the liquid introduction portion, and the closing surface has a flat surface portion, and an inclined surface portion formed around the flat surface portion and inclined toward an edge of the closing surface, and at least a part of the inclined surface portion faces the introduction portion flow path in mounted state.

A printing consumable, an ink cartridge, and an ink cartridge reforming method are provided in the present disclosure. A printing consumable includes a first nozzle circuit, configured to feed back a first signal in response to a detection signal transmitted by a printer; and includes a second nozzle circuit, configured to not respond to the detection signal transmitted by the printer or configured to feed back a second signal different from the first signal in response to the detection signal, where the first nozzle circuit includes a nozzle circuit that has not been reformed and the second nozzle circuit includes a nozzle circuit that has been reformed. The second nozzle circuit includes a first circuit and a second circuit which includes a first conversion circuit and/or a second conversion circuit.

In some examples an imaging device can include a fill port to receive a colorant container including an alignment circuit, a controller including a processing resource and memory resource including a non-transitory computer-readable instructions executable by the processing resource to detect a presence of a colorant container in a fill port of an imaging device, responsive to detection of the colorant container in the fill port, detect if the colorant container is properly inserted in the fill port, and cause a fill process to initiate responsive to detection that the colorant container is properly inserted.

A liquid storage container includes a storage chamber that stores a liquid, a filter chamber that is provided with a filter and receives the liquid from the storage chamber to filter the liquid by the filter, and a partition wall that separates the storage chamber and the filter chamber. The partition wall is provided with a communication hole structure that allows the storage chamber and the filter chamber to communicate with each other. A shape of one or more openings of the communication hole structure in the storage chamber is a shape in which a distance from a center of gravity of an entirety of the one or more openings to the closest point in a contour defining the one or more openings is smaller than a radius of a circle having the same area as an area of the entirety of the one or more openings.

A cartridge includes a liquid container and an adaptor. The liquid container has a liquid storage containing a liquid to be supplied to a printing apparatus, a liquid supply section configured to supply the liquid contained in the liquid storage to a liquid introduction section, and an adaptor mounting section. The adaptor is mounted on the adaptor mounting section and has a terminal placement section in which a cartridge-side terminal electrically connected to an apparatus-side terminal is disposed and an insertion aperture through which the liquid introduction section passes. The adaptor mounting section is provided with a mounting mechanism for mounting the adaptor, which has a predetermined constant shape.

A liquid discharge head includes an electric connecting portion between a flexible wiring substrate and a contact wiring substrate. The contact wiring substrate has a first surface on which a contact pad is provided and a second surface opposite the first surface. The electric connecting portion is disposed on the second surface side of the contact wiring substrate.

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.
