There is provided a liquid consuming apparatus including: a tank having a liquid storing chamber, an erected wall through which the liquid inside the liquid storage chamber is visible from outside of the tank, and an inlet which is formed to penetrate through the erected wall and via which the liquid is poured into the liquid storage chamber; a liquid consuming section which consumes the liquid stored in the liquid storing chamber; and a cover. A transmitting section and a checking section are formed in an upper surface, of the cover, under a condition that the cover is in the exposure position, the transmitting section configured to transmit information optically to a user of the liquid consuming apparatus and the checking section configured to prevent the liquid moving on a particular surface of the cover from arriving at the transmitting section.

An inkjet recording apparatus includes a tank, a recording head, a cover, a monitor, a cover sensor, an operation panel, and a controller. The cover is movable to cover a plurality of injection inlets associated with a plurality of ink chambers and to expose the plurality of injection inlets. The cover sensor outputs signal depending on position of the cover. The controller controls the monitor to display one of inquiry information and notification on the monitor depending on receipt of the signal from the cover sensor.

A printing system is disclosed. The printing system includes at least one physical memory device to store halftone calibration logic and one or more processors coupled with the at least one physical memory device to execute the halftone calibration logic determine an uncalibrated deposition distribution for each of a plurality of pel forming elements, determine a calibrated deposition distribution for each of the plurality of pel forming elements and determine calibration values for each of the plurality of pel forming elements.

A head unit of an ink jet printer is formed with a mist removing space for removing an ink mist generated when an UV ink is discharged by an ink jet head from a gap between the head unit and a table, where the mist removing space is formed with a gas introducing port, arranged at a position between the ink jet head and the LED, for the gas to be introduced from the gap side between the head unit and the table to the mist removing space, an intake port for the gas to be suctioned from the mist removing space toward a sirocco fan side by an airflow generated by the sirocco fan, and a gas discharging port, arranged separately from the intake port, for the gas to be discharged from the mist removing space.

A solvent or ink container plug includes a cylindrical base having an upper side and a lower side, the lower side being configured to face an inside of a container when the container is closed by the plug. The plug further includes a connection portion, connected to the upper side of the cylindrical base, the connection portion comprising at least two connection tips. The cylindrical base includes a first aperture and a second aperture provided at the lower side of the cylindrical base. Moreover, the first aperture and second aperture are each in communication with a corresponding one of the two connection tips. Further, the connecting portion has a side dimension, measured in a plane perpendicular to an axis of introducing the plug onto or into the container, that is smaller than the cylindrical base.

Provided are a printing result inspection apparatus, a method, and a program capable of determining a printing defect caused by a printing step and a printing paper defect caused by printing paper by reading the printing paper once. A defect determination unit determines whether defected regions extracted from a non-image region are the printing defect or the printing paper defect based on a density change amount and a color, and an image feature amount of a defected region determined as the printing paper defect in the non-image region is stored in paper defect information and is accumulated in a paper defect information storage unit. Next, the defect determination unit determines whether defected regions extracted from image regions are the printing defect or the printing paper defect based on the paper defect information.
