A liquid ejecting apparatus includes a liquid ejecting portion that has a supply port, a second discharge port, a plurality of nozzles, and a nozzle surface on which a plurality of the nozzles are open, and that discharges the liquid from the nozzles, a liquid supply flow path coupled to the supply port so that the liquid is supplied to the liquid ejecting portion, and a liquid return flow path coupled to the second discharge port so that the liquid supplied to the liquid ejecting portion is returned to the liquid supply flow path, in which a pressure lowering operation of lowering a pressure in the liquid ejecting portion is performed in a state where a flow of the liquid in the liquid return flow path is blocked after performing a pressurization discharge operation of pressurizing the liquid in the liquid ejecting portion and discharging the liquid from the nozzle.

Liquid ejecting apparatus and maintenance method of liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting portion having a filter configured to filter a supplied liquid and eject the liquid filtered by the filter from nozzles, a liquid ejecting portion holding portion replaceably holding the liquid ejecting portion, a liquid supply flow channel coupled to the liquid ejecting portion so as to supply the liquid to the liquid ejecting portion, a flow mechanism configured to flow the liquid, and a control portion configured to drive the flow mechanism to cause the liquid to flow in the liquid supply flow channel toward the liquid ejecting portion in replacement of the liquid ejecting portion.

Liquid ejecting apparatus and method of maintaining liquid ejecting apparatus

In a filling operation of filling liquid in a liquid supply flow path which includes a filter having holes by causing a pressure on a downstream side in the liquid supply flow path to be lower than a pressure on an upstream side, and a maximum pressure difference which occurs between an upstream side of the filter and a downstream side of the filter is larger than a pressure difference for destroying a gas-liquid interface formed in the hole in a case where the upstream side of the filter is the liquid, and the downstream side of the filter is gas, and is smaller than a pressure difference for destroying the gas-liquid interface formed in the hole, in a case where the upstream side of the filter is the gas, and the downstream side of the filter is the liquid.

Liquid ejecting apparatus and filling method of liquid ejecting apparatus

A liquid accommodation body that is removably installed in a liquid ejecting apparatus provided with a supply flow channel that supplies a liquid to a liquid ejecting portion, and a feedback flow channel that is connected to the supply flow channel so as to form a circulation flow channel, and is provided with a liquid accommodation portion that accommodates the liquid, a lead-out flow channel that connects a lead-out port, which is connected to the supply flow channel, and the feedback flow channel, an introduction flow channel that connects an introduction port, which is connected to the feedback flow channel, and the lead-out flow channel, and a filter portion that is provided in a partial circulation flow channel, which, among portions of the lead-out flow channel and the introduction flow channel, configures the circulation flow channel, and filters the liquid.

Liquid accommodation body and liquid ejecting apparatus

A liquid accommodating body includes a liquid accommodating chamber that accommodates liquid, a pouring port through which the liquid is poured into the liquid accommodating chamber, a visual recognition portion through which a surface of liquid accommodated in the liquid accommodating chamber is visually recognized and which is provided on a side wall forming the liquid accommodating chamber, a partition wall that partitions the liquid accommodating chamber into a pouring port side liquid accommodating chamber into which the liquid is poured through the pouring port and a visual recognition portion side liquid accommodating chamber including the visual recognition portion in a direction intersecting a gravity direction, and a liquid communication portion which is provided between the partition wall and a bottom wall forming the liquid accommodating chamber and through which the pouring port side liquid accommodating chamber and the visual recognition portion side liquid accommodating chamber communicate with each other.

Liquid accommodating body, liquid filling method, and liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid container containing section, and a pressurizing section that pressurizes inside of the liquid container containing section. The liquid container containing section has a casing that contains a liquid container, a mounting member that is mounted with the liquid container, and a cover that covers an opening that is formed in the casing, the mounting member is arranged inside the casing on the opening side, the cover is arranged outside the casing on the opening side, and the mounting member is fixed to the cover.

Liquid ejecting apparatus

A filter unit which is detachably mounted on a liquid ejecting apparatus including a liquid ejecting section which ejects liquid, the filter unit including a filter which filters the liquid; and a storage medium which stores information on the filter.

Filter unit and liquid ejecting apparatus

A liquid containermountable to a printing apparatusthat performs printing by discharging a liquid and capable of storing a liquid supplied in a pressurized state is provided with a liquid introduction partthrough which the liquid is introduced, a tankcapable of storing the liquid introduced from the liquid introduction part, and a liquid supply partthat supplies the liquid in the tankto a printing apparatus, and the tankis molded to have flexibility.

Liquid container

A liquid storage container supplies ink to a printer which consumes the ink, and includes a liquid storage body which includes a liquid lead-out port communicating with the printer and a filler port formed to pour the liquid to the liquid storage container, an auxiliary holding member which is mounted to be slidable to a side in which the filler port is formed, and a memory unit holding member which is detachably configured to the auxiliary holding member and includes a memory unit.

Liquid storage container

A liquid holding container includes a liquid accommodating chamber, a flow path, and a filter. The liquid accommodating chamber is configured and arranged to hold liquid. The flow path is communicated with the liquid accommodating chamber via a first through hole and a second through hole. The filter is disposed in the flow path. The first through hole and the second through hole are each communicated with the flow path.

Liquid holding container

A liquid container is configured to be placeable in a containing vessel having a pressurized space and a vessel-side liquid supply structure that is connected with a liquid consuming device. The liquid container comprises a liquid container body; a liquid supply structure that is configured to supply a liquid contained in the liquid container body to the vessel-side liquid supply structure; a container body holding assembly that is configured to hold the liquid container body; and a substrate holding structure that is provided in the container body holding assembly. The container body holding assembly is positioned relative to the containing vessel such that the liquid container body and the liquid supply structure are placed inside of the pressurized space and the substrate holding structure is placed outside of the pressurized space.

An ink supply apparatus is an apparatus for supplying ink to a printer, the printer including a holder provided with an ink receiving part. The ink supply apparatus includes an ink supply passage member connected to the ink receiving part, and an ink container in fluid communication with the ink receiving part through the ink supply passage member. The ink container including an ink discharge port at an upper portion thereof.

Ink supply apparatus
