A consumables management system includes a plurality of printers in each of which a consumables container is installed and each of which is configured to consume consumables contained in the consumables container, and a management unit connected via a network to the plurality of printers. The management unit manages container identification information assigned to the consumables container, device identification information assigned to each of the plurality of printers, and user identification information assigned to the user of each of the plurality of printers in association with one another.

A printing device includes a printing unit configured to use ink stored in an ink cartridge to perform printing on a medium, a remaining amount detector configured to detect a remaining amount of the ink stored in the ink cartridge, a maintenance unit configured to perform maintenance on the printing unit, and a display unit configured to perform predetermined notification regarding either replacement of the ink cartridge or refilling of the ink cartridge with the ink. Either the printing device or a server device includes a selector configured to select either the maintenance to be performed or the predetermined notification based on the remaining amount of the ink when an amount of the ink used for a predetermined time period is equal to or smaller than a defined amount based on information on the amount of the ink used.

Printing system and printing device

A printing apparatuscalculates an consumed ink amount which is a consumed amount of ink ejected from an ejection unit that ejects ink supplied from an ink cartridge, and, in the case where an unused ink cartridgeis installed, executes initial maintenance of the ejection unit, determines an initial consumed ink amount which is a consumed amount of liquid consumed by the initial maintenance, writes the consumed ink amount and the initial consumed ink amount to a storage deviceof the ink cartridgeas a consumed ink amountand an initial consumed ink amount, and generates and notifies a ratio of the difference between the contained ink amountand the consumed ink amount that is updated relative to the difference between the contained ink amountand the initial consumed ink amountas notification-use information.

An ink supplying and collecting apparatus includes a case, ink cartridges detachably attached to the case, and a collecting container detachably attached to the case. The ink cartridges supply ink to a recording head of a printer via ink supply tubes. The collecting container collects ink drained from the recording head via an ink drain tube. The case is located outside of and is separate from the printer. Thus, the sizes and shapes of the ink cartridges and the collecting container can be freely designed.

Liquid supplying and collecting apparatus

A printing apparatus includes a detection unit that detects the amount of residual ink in a ink cartridge, and a control unit that controls of initial filling of a printing head, in which the control unit performs initial filling when a state of the amount of residual ink detected by the detection unit is equal to or more than a predetermined amount, and the amount of residual ink based on information on the amount of ink stored in a storage unit is equal to or more than a predetermined value.

Printing apparatus

A guiding device guides, in a main body of a liquid ejection apparatus, a flexible passage forming member having a passage therein in a predetermined routing direction while curving the passage forming member. The guiding device includes a holding member. The holding member is engaged with a curved section of the passage forming member, and holds the curved section in an undeformable manner in the apparatus main body. The holding member guides the passage forming member in the routing direction. Thus, the guiding device is capable of efficiently routing passage forming members while bending the members in a body of a liquid ejection apparatus.

Liquid passage forming member guiding device

[The present invention] provides a surface treatment method for recorded matter which can improve the weather resistance characteristics such as light resistance, gas resistance and the like of recorded matter in which images are recorded on the recording medium, as well as providing a surface-treated product using this surface treatment method, and a surface treatment apparatus. The surface treatment method of the present invention is characterized in that the surface of recorded matter in which images are recorded on a recording medium is treated using a specified treatment agent. The abovementioned treatment agent is a treatment agent which contains one or more active constituents selected from the group consisting of sulfur compounds, nitrogen compounds, fluorine compounds, natural resins and synthetic resins, or a treatment agent comprising water or an organic solvent.

Method for treating surface of ink jet recording medium having recorded image

An ink-jet recording material having on a support at least an ink-receiving layer, with the ink-receiving layer being comprised of a light resistance-imparting layer as a lower layer and a coloration layer as an upper layer. Herein, the light resistance-imparting layer comprises a light-resistance imparting chemical constituted of 1 to 10 parts by weight of a benzotriazole compound as ultraviolet absorbent, 1 to 8 parts by weight of magnesium sulfate and 1 to 10 parts by weight of zinc oxide in combination with 100 parts by weight of an ink absorbing pigment, and besides, the coloration layer contains no light resistance-imparting chemicals.
