BACKGROUND

Field

The present disclosure relates to a liquid ejection apparatus.

Description of the Related Art

Liquid ejection apparatus, which typically include inkjet recording apparatus, basically comprise a liquid ejection head and a liquid container containing liquid to be fed to the liquid ejection head. An image is recorded by the liquid ejection head as liquid is ejected from the liquid ejection head to the outside. The liquid containers of liquid ejection apparatus include removable cartridge type containers that can be replaced when the liquid in the container is almost gone and stationary type containers that can be refilled with liquid from the outside when only an insufficient amount of liquid is left in the container. Stationary type liquid containers have a refilling port by way of which the liquid is refilled. The refilling port is normally closed with a cap or the like. When the liquid is to be refilled, the cap is removed to expose the refilling port and a part of an external liquid container (e.g., bottle) is put into the refilling port to transfer the liquid in the external liquid container into the stationary liquid container.

There are liquid ejection apparatus having two or more stationary type liquid containers. Such liquid ejection apparatus are accompanied by a risk that some of the containers can unexpectedly and mistakenly be refilled with wrong liquid. For instance, one of the containers that is a container for containing cyan ink can be refilled with yellow ink. When one of the containers of such a liquid ejection apparatus is unexpectedly and mistakenly refilled with wrong liquid, the recording operation of the liquid ejection apparatus can adversely be affected and/or the liquid ejection apparatus can be damaged. In view of this sort of problems, Japanese Patent Application Laid-Open No. 2018-39225 discloses an arrangement with which a portable information terminal reads out the two-dimensional code attached to a bottle and transmits it to its management server and the management server verifies the received information on the liquid contained in the bottle. If the management server finds that the content of the bottle is not a right one, it displays an error message on the portable information terminal to tell that the content of the bottle is not a right one. Meanwhile, Japanese Patent Application Laid-Open No. 2016-30386 discloses an arrangement for communications between the RF tag applied to an ink pack and the communication unit of a printing apparatus (liquid ejection apparatus) for the purpose of referring by the control unit of the printing apparatus to the information on the ink color and the instruction for the use of the ink contained in the ink pack. If the ink pack is found to be a wrong one as a result of the reference, a warning message is displayed and/or a voice warning is issued by the control unit of the printing apparatus.

With either of the arrangement described in Japanese Patent Application Laid-Open No. 2018-39225 and the arrangement described in Japanese Patent Application Laid-Open No. 2016-30386, when the liquid in the bottle is found to be incorrect liquid, the portable information terminal of the printing apparatus of the former patent literature or the control unit of the printing apparatus of the latter patent literature, displays a warning message and/or a voice warning is issued from it. However, there still remains a risk that the user of the liquid ejection apparatus may not be attentive enough and may fail to recognize the warning and mistakenly refill the liquid container with the incorrect liquid to seriously damage the recording operation. Additionally, with either of the arrangement described in Japanese Patent Application Laid-Open No. 2018-39225 and the arrangement described in Japanese Patent Application Laid-Open No. 2016-30386, the user cannot recognize a situation where the assumed liquid is contained in the external container, which may be a bottle or an ink pack, in inappropriate conditions because, for example, the liquid has evaporated to a considerable extent. In other words, if the liquid is an appropriate one in terms of type and/or color but held in the external container in inappropriate conditions and hence the liquid container of the liquid ejection apparatus is refilled inappropriately, the recording operation can also adversely be affected. In short, the effect of preventing the above that are attributable to refilling operation from taking place of the arrangement described in Japanese Patent Application Laid-Open No. 2018-39225 and the arrangement described in Japanese Patent Application Laid-Open No. 2016-30386 has limitations.

SUMMARY

A liquid ejection apparatus according to the present disclosure includes a liquid container configured to contain liquid and has a refilling port for refilling the liquid container with liquid, a contained liquid information memory unit configured to store information on the liquid contained in the liquid container, a refilling liquid information memory unit configured to store information on the liquid to be supplied for refilling the liquid container, a liquid ejection head configured to eject the liquid supplied from the liquid container, and a control unit configured to control an operation of the liquid ejection apparatus according to the information stored in the contained liquid information memory unit and the information stored in the refilling liquid information memory unit.

Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
