Disclosed herein is a fluid supply system that can provide fluid to a jetting assembly at a constant pressure or at pressures within a desired range of pressures. In an example, the fluid can be ink, and the jetting assembly can be a print head configured for dispensing the ink.

An inkjet recording device includes a first tray for supporting sheets, a storage body for storing ink, a head for ejecting ink, a platen positioned between the head and the first tray, and a first guide member. The platen is configured to support a first surface of the sheet conveyed rearward at a position below the head. The first guide member is positioned frontward of the head and has a first curved surface configured to guide the first surface of the sheet conveyed from the first tray toward the platen. The first guide member has a portion arranged in alignment with the storage body in a widthwise direction perpendicular to an up-down direction and a front-rear direction. The first guide member has a portion positioned at the same height as the storage body in the up-down direction.

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 determination is made on whether or not a recording medium is held in a state where calibration is executable, and the execution is pending in a case where the recording medium is not held. When the execution is pending, the determination is made again after a predetermined period elapses, and the calibration is executed in a case where the recording medium is held.

A tank includes: a wall separating a liquid storage chamber, which stores a liquid to be supplied to a liquid consuming part, from an outside; an inlet penetrating the wall; and a liquid outflow part which allows the liquid to flow to the outside of the liquid storage chamber. The wall includes a view wall, which extends upward and downward and allows a user to visually check a liquid level in the liquid storage chamber, and a bottom wall, which defines an inner bottom surface of the liquid storage chamber by being connected to the view wall. The inner bottom surface of the bottom wall includes an inclined part which extends from at least a part of the view wall to incline downward in a direction away from the view wall.

A waste liquid box management method sets a type of ink to be contained in a container, for a waste liquid box that includes a coupling portion coupled to a printer, the container containing ink discharged from the printer via the coupling portion, and a storage unit. The waste liquid box management method individually allocates different storage regions, in the storage unit, to a plurality of ink types, writes predetermined type specification data into a selected storage region, that is the storage region allocated to the ink type to be contained in the container, and inhibits writing to the storage region other than the selected storage region in a state in which data other than the type specification data is stored therein.

A printer includes a recording unit, a platen unit, a maintenance tank, and a guide unit. The recording unit ejects ink onto a medium. The platen unit includes a support surface that supports the medium and a discard portion in which waste ink is discarded. The maintenance tank recovers the waste ink. The guide unit has a receiving surface, and guides the waste ink to the maintenance tank. Second surface energy is larger than first surface energy when the first surface energy indicates surface energy at a first position on the receiving surface with respect to the waste ink and the second surface energy indicates surface energy at a second position closer to the maintenance tank than the first position.

An image forming system includes a fluid applicator unit, a substrate positioning unit, and a fluid collector assembly. The fluid collector assembly includes a collector substrate, a collector advancement unit, and a collector control module. The fluid applicator unit may apply fluid to a substrate. The substrate positioning unit may position the substrate in a printzone to receive the fluid from the fluid applicator unit such that a first portion of the fluid remains on the substrate and a second portion of the fluid does not remain on the substrate. The collector substrate may collect the second portion of the fluid in the printzone below the substrate. The collector advancement unit may advance the collector substrate along a collector transport path below the substrate in the printzone. The collector control module may control the collector advancement unit to selectively advance the collector substrate along the collector transport path in response to application of the fluid to the substrate by the fluid applicator unit.
