A liquid absorber includes a plurality of small parts each including a first layer containing fibers, a second layer containing fibers, and a third layer which contains a water absorbing resin and which is provided between the first layer and the second layer. When the water absorbing resin is measured in accordance with a plastic thermogravimetric measurement method defined by JIS K 7120: 1987 under measurement conditions in which a sample amount is 5 to 15 mg, a temperature increase rate is 10.0 C./min, and a measurement atmosphere is nitrogen, from a TG curve obtained thereby, the ratio of a weight decrease amount of the water absorbing resin at 400 C. with respect to an initial weight thereof is 0.050 to less than 0.500.

A waste fluid quantity measuring device can comprise a waste fluid tank for recovering a waste fluid, a placement platform on which the total mass of the waste fluid tank acts, a motive force portion for moving at least a portion of the placement platform from a first position to a second position, with a constant force. A sensor can measure a position of the placement platform and a measuring portion can move the placement platform and measure a movement time of the placement platform to the second position, based on a measurement result by the sensor. An evaluating portion can evaluate a state of storage of waste fluid of the waste fluid tank based on the movement time measured by the measuring portion and a correspondence of the movement time and the quantity of waste fluid within the waste fluid tank.

An inkjet printer includes a support table supporting a waste liquid tank and being displaceable in accordance with a weight of the waste liquid tank, a first sensor to detect that the support table has reached a first position, a second sensor to detect that the support table has reached a second position, a first determinator to determine that the waste liquid tank is in a near-end state when the support table is detected by the first sensor to have reached the first position, and a notifier to notify a user of the near-end state when the first determinator determines that the waste liquid tank is in the near-end state.

A liquid collection device includes: a suction tank configured to suck and collect liquid accumulated in a liquid reservoir; a suction passage connecting the liquid reservoir and an inlet opened in a lower portion of the suction tank to each other; a suctioner configured to generate a negative pressure in the suction tank and suck the liquid from the liquid reservoir into the suction tank via the suction passage by using the generated negative pressure; and a controller configured to control the suctioner to terminate suction of the liquid into the suction tank upon continuance of a state where a pressure in the suction tank is equal to or greater than a threshold for a prescribed time or more after start of the suction.

A liquid absorber includes a plurality of small chips. Individual ones of the small chips include a first substrate containing fibers, a second substrate containing fibers, an absorbent resin supported between the first substrate and the second substrate, and an ion exchange resin supported between the first substrate and the second substrate. At least one of the absorbent resin and the ion exchange resin is exposed at an end face of the small chips.

A liquid ejecting apparatus includes a transport section which transports a medium in a transport direction, a liquid ejecting head which ejects a liquid onto the medium, a carriage which supports the liquid ejecting head, a liquid storage container which stores the liquid to be supplied to the liquid ejecting head, and an discharge section which discharges the medium onto which the liquid is ejected. The liquid ejecting apparatus further includes a holding section which holds a waste liquid box configured to store the liquid eliminated from the liquid ejecting head as a waste liquid. The holding section is disposed at a position downstream of the carriage in the transport direction and above the discharge section.

An ink mist recovery device allows suction of ink mist with uniform suction force irrespective of a position on a confronting sheet. The ink mist recovery device includes a recovery casing having multiple suction ports confronting a sheet, and a suction unit connected to the recovery casing. At least one of a size of each of the suction ports and a first suction distance from each of the suction ports to a suction slit is set in accordance with a second suction distance from the suction unit to the suction slit via each of the suction ports so that the suction force is kept uniform at the respective positions on the sheet corresponding to the suction ports. The mist suction force is made uniform over the entire width of the suction slit to improve quality of the printed image without sucking ink droplets required to land.

A liquid absorber includes a liquid absorption member, a case, and a cover. The liquid absorption member absorbs liquid. The liquid absorption member includes a fiber and a liquid-absorbent resin. The liquid absorption member is stored in the case. The cover covers the liquid absorption member. The cover includes through-holes through which the liquid is to pass. The cover includes a recessed portion recessed toward the liquid absorption member. The recessed portion is disposed at a location to which the liquid is to be discharged. The through-holes are disposed at least in the recessed portion.

A liquid absorber includes a plurality of small parts each including a first layer containing fibers, a second layer containing fibers, and a third layer which contains a water absorbing resin and which is provided between the first layer and the second layer. When the water absorbing resin is measured in accordance with a plastic thermogravimetric measurement method defined by JIS K 7120: 1987 under measurement conditions in which a sample amount is 5 to 15 mg, a temperature increase rate is 10.0 C./min, and a measurement atmosphere is nitrogen, from a TG curve obtained thereby, the ratio of a weight decrease amount of the water absorbing resin at 400 C. with respect to an initial weight thereof is 0.050 to less than 0.500.
