The cartridge attachment portion and the power transmission mechanism are positioned at the same side of the holder in the leftward/rightward direction. An occupying range of the maintenance unit is across respective occupying ranges of the cartridge attachment portion and the power transmission mechanism in the leftward/rightward direction.

A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising an airflow guide structure extending into the opening of the carrier plate, the airflow guide structure configured to flow air at a direction aimed under the printhead and at an oblique angle relative to the movable support surface. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

A liquid discharging apparatus includes: a first storage which stores liquid; a first detector which detects an amount of the liquid in the first storage; a communication hole communicating the first storage and outside; a semipermeable membrane arranged to cover the communication hole; a head unit having at least one nozzle which discharges the liquid supplied from the first storage; a liquid flow channel which communicates the first storage and the head unit; a cap which seals the nozzle of the head unit; a cap movement mechanism which moves the cap; an electrode arranged in the cap and on which the liquid discharged from the nozzle is landed; a second detector connected electrically to the electrode; a suction mechanism which sucks the liquid and gas inside the cap; a waste liquid storage which stores the liquid sucked from inside of the cap by the suction mechanism; and a controller.

A printer includes a line head and a waste liquid tank. The line head is configured to move in an A direction having a component of a horizontal direction and a component of an apparatus height direction and is configured to eject a liquid onto a sheet to make a record. The liquid ejected from the line head is collected in the waste liquid tank. The waste liquid tank is located below the line head in the Z direction. When viewed in the Z direction from top to bottom, a movement area of the line head and a portion of the waste liquid tank overlap each other over a range defined in the Y direction.

There is provided a liquid discharge apparatus including: a head including a nozzle configured to discharge a liquid, and a driver element configured to apply a pressure to the liquid; a tank configured to store the liquid; a circulation channel configured to circulate the liquid between the head and the tank; a pump; and a controller. The controller is configured to carry out: a non-discharge flushing process of performing a non-discharge flushing by driving the driver element such that the liquid is not discharged from the nozzle; a switching process of switching the pump between ON and OFF; and a determining process of determining a frequency of driving the driver element in the non-discharge flushing process according to a circulation flow amount of the liquid changing due to the switching of the pump between ON and OFF in the switching process.

A printing apparatus includes a printing unit configured to apply ink containing a coloring material, and a reactive liquid that reacts with the ink, to a printing medium, a reading unit configured to read an ink image on the printing medium, a printing control unit configured to cause the printing unit to print a plurality of ink images different in application amount of the reactive liquid on the printing medium, and a determination unit configured to determine an application amount of the reactive liquid in printing using a predetermined type of printing medium, based on a correlation between a plurality of reading results obtained by the reading unit by reading the plurality of ink images printed on the predetermined type of printing medium.

In some examples a printing system includes purging manifolds. The printing system includes a fluid ejection device to dispense a fluid and a first reservoir to house a fluid. The system further includes a purging manifold to fluidically couple to the fluid ejection device, and the purging manifold to fluidically couple to the first reservoir. The purging manifold includes a second reservoir. The purging manifold further includes a supply port; a fluid inlet port; and a purging outlet port. The purging outlet port is disposed above the supply port to convey fluid to the first reservoir. The printing system also includes a fluid interface connector to fluidically connect to the supply port and fluidically connect to the fluid ejection device.
