A liquid ejecting apparatus comprises a liquid ejecting head ejecting liquid, an identification information acquisition device configured to acquire identification information from the liquid ejecting head, a storage device in which the identification information is stored, and a control device configured to, in a case in which, when a replacement for the liquid ejecting head is made, the liquid ejecting head being a replacement target has been attached again, notify that the liquid ejecting head being the replacement target is in an attached state again, based on the identification information stored in the storage device.

Liquid ejecting apparatus and driving method for liquid ejecting apparatus

A liquid ejection head includes a nozzle face provided with a nozzle configured to eject a liquid, a cap member configured to contact the nozzle face at a position enclosing the nozzle and to be fitted so as to cover the nozzle, the cap member being formed with an atmosphere communication hole to place an inside of the cap member and a surrounding atmosphere in communication with each other, and a clog determination mechanism configured to determine whether or not the atmosphere communication hole is in an at least partially blocked state.

Liquid ejection device and method for driving liquid ejection device

A liquid ejecting apparatus includes a liquid ejecting head having N nozzle line groups (N is an integer equal to or larger than 3) arranged in a first direction, a main scanning section configured to move the liquid ejecting head in a second direction which intersects with the first direction for scanning, a selection section configured to select a set of use nozzle lines to be used for formation of dots on the medium from among the N nozzle line groups, and an ejection controller configured to form the dots by causing the nozzles included in the set of use nozzle lines selected by the selection section to eject the liquid. The selection section selects M of the N nozzle line groups (2&#x2264;M&#x3c;N) which are consecutively adjacent to each other in the first direction as the set of use nozzle lines.

Liquid ejecting apparatus and method for driving the same

A printing apparatus includes a liquid ejecting section that is capable of ejecting a reactant liquid and an ink, and a control section that controls operation of the liquid ejecting section. The control section sets an ejection duty of the reactant liquid according to an ejection duty of the ink.

Printing apparatus and printing system

A liquid ejecting apparatus includes a transport mechanism which transports a medium in a first direction; a pre-treatment liquid coating mechanism which coats a pre-treatment liquid on the medium; a liquid ejecting unit which includes a plurality of ink nozzles which eject ink; and a control unit which controls the pre-treatment liquid coating mechanism and the liquid ejecting unit, in which the pre-treatment liquid coating mechanism includes a first mechanism which is disposed in a first region A and a second mechanism which is disposed in a second region B positioned on an upstream side of the first region A in the first direction, and the plurality of ink nozzles has a portion which overlaps with respect to the first mechanism in a second direction which intersects with the first direction and a portion which does not overlap with respect to the second mechanism in the second direction.

Liquid ejecting apparatus and liquid ejecting method

A liquid ejecting apparatus includes a forming section which forms an image on a medium, a transport section which transports the medium in a first direction, and a heating section which heats a transport path on which the medium is transported, in which the forming section includes a first forming section which forms a pre-treatment liquid layer that includes a thermosetting resin on the medium, a liquid ejecting head which forms an image layer on the medium by ejecting liquid, and a second forming section which forms a post-treatment liquid layer that includes a thermosetting resin and is different from the pre-treatment liquid layer on the medium, and B&#x3c;A and B&#x3c;C in a case where content of the thermosetting resin in the pre-treatment liquid is A, content of the thermosetting resin in the liquid is B, and content of the thermosetting resin in the post-treatment liquid is C.

Liquid ejecting apparatus

There is provided an ink jet recording method for printing a pigment in which a pigment printing ink composition including at least pigment as a colorant is discharged from a nozzle opening as an ink droplet having an amount of the ink of the ink droplet of 9 ng or less with an average discharging speed V of 5 m/s or greater at a distance in the range of 0.5 mm to 1.0 mm in the direction from the nozzle opening to cloth, and whereby the pigment printing ink composition is adhered to the cloth.

Ink jet recording method for printing pigment

An ink jet recording method is provided in which an ink jet head having a first nozzle array and a second nozzle array which is arranged along the first nozzle array, in which the distance between the first nozzle array and the second nozzle array is 15 mm or greater and a nozzle density of the first nozzle array and a nozzle density of the second nozzle array are 600 dpi or greater is used, and while varying the relative position of the ink jet head in a direction intersecting an array direction of the first nozzle array and the second nozzle array with respect to a recording medium, an ink composition is adhered to the recording medium by performing a scanning which discharges the ink composition at a frequency of 12 kHz or greater from nozzles in the first nozzle array and the second nozzle array.

Ink jet recording method

A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid from a nozzle toward a target which is positioned away from a nozzle forming surface where the nozzle is formed; a wiping member that is capable of wiping the nozzle forming surface; a movement mechanism that relatively moves the liquid ejecting head and the wiping member when wiping is carried out; and a control portion that controls the movement mechanism so as to cause a relative moving velocity between the liquid ejecting head and the wiping member to be lower when wiping is carried out in a case where the liquid is ejected at a second distance of which an opposing distance between the nozzle forming surface and the target is longer than a first distance compared to a case where the liquid is ejected at the first distance of the opposing distance.

Liquid ejecting apparatus and maintenance method

A minute vibration driving signal is configured to include a first signal section which generates a plurality of minute vibration driving pulses, and a second signal section which maintains potential to a constant level without generating the minute vibration driving pulse, and can select a first mode in which duration of the second signal section is set to Twhich is longer than duration Tof the first signal section, and a second mode in which duration of the second signal section is set to Twhich is longer than T

Liquid ejecting apparatus and controlling method thereof

There is provided a clear ink composition containing a water-insoluble alkanediol having at least seven carbon atoms, a water-soluble alcohol that functions as a dissolution aid for dissolving the water-insoluble alkanediol, water, a fine polymer particle at least containing polyolefin, and a fluorene resin.
