A liquid absorbing sheet includes: a receiving base material which has a liquid permeability and which includes a first base material, a second base material, and a bonding portion at which the first base material and the second base material are bonded to each other at margins thereof, the first base material and the second base material each being composed of a material including fibers; and a water absorbing resin which has a water absorbing property, which is swelled in association with water absorption, and which is received in a portion between the first base material and the second base material surrounded by the bonding portion. In the liquid absorbing sheet described above, the bonding portion is at least partially broken when the water absorbing resin is swelled.

A liquid absorber of the present disclosure includes: a first base material; a second base material; and an absorption layer provided between the first base material and the second base material, in which the first base material and the second base material both contain a flame-retardant filament nonwoven fabric, and a content of a flame retardant in the absorption layer is less than 10% by mass.

A liquid ejecting apparatus includes a liquid ejecting head configured to eject a liquid onto a medium; a maintenance unit that performs a maintenance operation for the liquid ejecting head; a mounting mechanism in which is mounted a waste liquid container that houses a portion of the liquid discharged as a waste liquid from the liquid ejecting head; and an access area that is provided vertically below a transport path along which the medium is transported and that is accessible from an apparatus front side, which is a downstream side in a transport direction in which the medium is transported, the mounting mechanism including a housing portion that houses the waste liquid container and being disposed so that a mounting port for mounting the waste liquid container in the housing portion opens to the access area.

At least some issues such as making it difficult for liquid to leak to the outside, making it easy for liquid contained in a buffer chamber to return to a liquid storage portion, and suppressing an increase in the installation area of the entirety of a printing apparatus is achieved. A liquid supply apparatus includes a liquid tank that contain a liquid, a connection channel member connected to the liquid tank, and a buffer tank that is configured separately from the liquid tank, is connected to the liquid tank via the connection channel member, and is communicated with the atmospheric air. The liquid tank includes a liquid storage chamber provided inside of the liquid tank, and a liquid inlet portion for injecting liquid into the liquid storage chamber. The buffer tank has a buffer chamber, bottom face of the buffer chamber is positioned at a position higher than a maximum liquid level of the liquid tank.

A liquid ejecting apparatus includes a liquid ejecting unit that can eject a first liquid and a second liquid to a medium, a first rotating body having a circumferential surface that can receive the first liquid ejected from the liquid ejecting unit, a first sliding contact member that can be slidably in contact with the circumferential surface of the first rotating body, a first collection unit that collects the first liquid that is collected from the circumferential surface by the first sliding contact member, a second rotating body having a circumferential surface that can receive the second liquid ejected from the liquid ejecting unit, a second sliding contact member that can be slidably in contact with the circumferential surface of the second rotating body, and a second collection unit that collects the second liquid that is collected from the circumferential surface by the second sliding contact member.

Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a porosity determiner determines a porosity of a print medium and a signal generator generates a signal relating to a state of a printing fluid collector based on the porosity determined. In an example of a method of operating a printing system, a pressure measurement is obtained from a vacuum system of the printing system when a print medium is present on a media path of the printing system. This is compared to at least one predefined pressure range and, based on the comparison, an indication is provided setting out a state of a printing fluid collector.

An inkjet printer includes: at least one ink receptor having a tray shape with a bottom plate and an opening facing upward and being horizontally movable; and a suction unit. The at least one ink receptor is configured to receive ink ejected from at least one inkjet head as waste liquid. The suction unit includes at least one suction nozzle arranged above the bottom plate within a movable range of the at least one ink receptor and is configured to suction the ink in the at least one ink receptor through the opening with the at least one suction nozzle.

An inkjet printer includes an ink head including a nozzle surface with nozzles, and an attachment portion to enable attachment or detachment of an ink refill container storing ink to be ejected from the nozzles or a washing liquid refill container storing a washing liquid usable to wash the nozzle surface. The attachment portion includes a housing to accommodate the ink refill container or the washing liquid refill container, a connection portion provided inside the housing and connectable with the ink refill container or the washing liquid refill container, and a tray provided in the housing and below the connection portion.

A liquid ejecting apparatus includes a liquid ejecting head and a mounting unit. The liquid ejecting head is able to eject liquid. A plurality of liquid containers containing the liquid to be supplied to the liquid ejecting head mounted so as to overlap in an up-down direction. The mounting unit includes a separator and an electrical member. The separator separates, in the up-down direction, a space where the plurality of liquid containers are mounted. The electrical member allows electricity to flow therethrough. The separator has a through portion that penetrates through the separator in the up-down direction. The through portion is positioned such that, when seen in the up-down direction, an edge portion of the through portion does not overlap with the electrical member positioned below the through portion.

A spittoon system for a printing mechanism includes a reservoir elongated in a longitudinal direction and having a bottom part. The reservoir receives printing fluid residue spit from a print-head onto a first zone of the reservoir. The spittoon system further includes a cleaning element arranged inside the reservoir to transfer, by sliding along the longitudinal direction of the reservoir, the received printing fluid residue from the first zone to a second zone. The second zone includes a drain outlet to drain the printing fluid residue from the reservoir.
