In one example, a printing fluid delivery system for a printer is described. The printing fluid delivery system includes a plurality of interconnected printing fluid supply modules forming a page-wide printing fluid manifold to supply printing fluid from one or more cartridges to one or more printheads along a print bar in a printer.

The remaining amounts of inks in tanks are obtained, and, based on the obtained results, whether direction for printing an image next is to be inverted with respect to a set direction. This can reduce a difference in ink remaining amount between the tanks corresponding to print heads.

A recording apparatus including a recording unit that performs recording by discharging a liquid on a medium transported in a transport direction, a liquid storage portion that is disposed on an apparatus front side in an apparatus depth direction and that includes a liquid container that contains the liquid discharged from the recording unit, and a maintenance unit that performs maintenance on the recording unit. In the recording apparatus, the maintenance unit is provided in an end portion area on a first direction side in a width direction, the width direction being a direction intersecting the depth direction, and the liquid storage portion is provided in an end portion area on a second direction side, the second direction side being a side opposite the first direction side in the width direction, the liquid storage portion extending in the depth direction to an occupying area of the maintenance unit.

The ink container includes an ink pack, a paper case and a cover. The ink pack is configured to store ink. The paper case is configured to store the ink pack and to have a shape elongated in one direction. The cover is bonded to an end portion in the one direction of the case. A protection rib is protruded on an outer circumferential face of the cover. The protection rib covers, from an outside in the one direction, a bonded portion of the end portion of the case and the cover.

A bottle for ink supply is shipped with a two-dimensional code attached to the bottle, individual information being embedded in the two-dimensional code. A user reads the two-dimensional code with a portable information terminal and thereby transmits the individual information to a management server. If there is no fraud or problem, the management server transmits a passcode to the portable information terminal. When the bottle is placed in a bottle storing unit, the two-dimensional code is read by a two-dimensional code reader, and a passcode is created based on the individual information embedded in the two-dimensional code. Only when the passcode matches the passcode registered by the user, ink in the bottle becomes ready to use.

Provided is a highly-convenient ink replenishment container. The ink replenishment container includes: a container main body portion capable of containing the ink; and an ink outlet forming portion that is to be attached to an end portion of the container main body portion and at which an ink outlet through which the ink flows out is formed. In a region located outside of the ink outlet, the ink replenishment container includes an erroneous insertion prevention portion that protrudes relative to the ink outlet in a direction opposite to the container main body portion in an axial direction as an axial center, and is configured to be inserted into a recessed portion and to prevent erroneous insertion into the ink tank. The erroneous insertion prevention portion includes protrusions that can be attached and detached, the protrusions are attached and detached in accordance with the shape of the recessed portion.

An image-recording apparatus includes: a first tank defining a first storage chamber; a second tank defining a second storage chamber; a conveying mechanism for conveying sheets along a conveying path extending in a depthwise direction and a widthwise direction perpendicular to a vertical direction and the depthwise direction; and a recording head including a nozzle. Liquid in the first storage chamber is supplied through a communication port to the second storage chamber and then to the recording head through a liquid outlet port. The second storage chamber is positioned further in a first depthwise direction relative to the nozzle and further in a first widthwise direction relative to the conveying path. A volume of a prescribed space above a liquid level equal to a height of the communication port in the second storage chamber is greater than that of a liquid channel between the liquid outlet port and the nozzle.
