The present invention processes media at an appropriate position. A media processing device (100) is provided with a table (10), a head (20), a relative movement mechanism (30), and a control unit (40). When the table (10) and the head (20) are being moved in a relative fashion at a predetermined relative speed in a main scanning direction and media is being processed, the control unit (40) controls a processing parameter of the timing of processing by a processing unit and/or the height of the processing unit on the basis of a gap between the head (20) and either a placement surface or a reference surface that is an upper surface of the media. If a corrected parameter obtained by correcting the processing parameter has been set on the basis of the difference between the actual gap over the reference surface and a reference value for the gap, then processing is controlled so as to be performed with this corrected parameter.

The present invention provides a printing device with which a device size reduction is possible. This printing device comprises: a table having a placement surface on which food is placed; and a carriage on which a head that discharges edible ink toward the food and an ink supply unit that supplies ink to the head are mounted and which is movable in a main scanning direction along the placement surface.

The present invention more appropriately irradiates a medium with ultraviolet rays. A printing device 10 uses an ultraviolet curable ink to perform printing on a three-dimensional medium 50 held by a holding jig 40 which is a holding member. The printing device 10 includes an inkjet head 102, a sub-scanning drive part 18, and a control part 30. The holding jig 40 includes a rotation mechanism, an ultraviolet irradiator, and a cover. The control part 30 causes the inkjet head 102 to perform a main scanning operation by causing the inkjet head 102 to discharge the ink while causing the rotation mechanism to rotate the medium 50 and causes the inkjet head to perform a sub-scanning operation within a range such that the position of a nozzle row in the sub-scanning direction remains within an opposing position medium range when the range from one end to the other end of the medium 50 in the sub-scanning direction at a position opposing the nozzle row is defined as the opposing position medium range.

The present invention provides a printing device with which easy device maintenance is possible. The printing device includes: a table having a placement surface on which food is placed; a carriage on which a head for discharging edible ink toward the food is mounted and which can move in a main scanning direction with respect to the table; and a carriage drive part which has a guide bar arranged along the main scanning direction and guiding the carriage, a movable part movable along the guide bar and connected to the carriage, and a drive source for moving the movable part in the main scanning direction. The carriage can be attached to and detached from the movable part.

Provided is an inkjet printer capable of continuing a printing operation even during replacement work of a main tank, the inkjet printer including: an inkjet head for discharging ink; a sub-tank for accommodating the ink to be supplied to the inkjet head; and a main tank for accommodating the ink to be supplied to the sub-tank. An inkjet printer 1 is provided with: an inkjet head 5; a sub-tank 11; a main tank 17; a buffer tank 18 which is disposed in a piping path between the sub-tank 11 and the main tank 17, and in which ink is accommodated; a pump 19 which is disposed in a piping path between the sub-tank 11 and the buffer tank 18; and a check valve 20 which is disposed in parallel with the buffer tank 18 in a piping path between the main tank 17 and the pump 19, and which allows a flow of ink only in a direction from the main tank 17 to the pump 19.

The present invention performs printing on a transfer medium in a more appropriate manner. This printing device 12, which performs printing by an inkjet method on a transfer medium 50 which is a medium for a transfer film, comprises: a head unit 102 which discharges ink to the transfer medium 50; a main scanning drive unit 108 which causes the head unit 102 to perform a main scanning operation; and a sub-scanning drive unit 110 which causes the head unit 102 to perform a sub-scanning operation. The head unit 102 includes a color head 202 which is a first inkjet head for discharging color ink, and a white ink head 204 which is a second inkjet head arranged with the position thereof in the sub-scanning direction shifted relative to the color head 202.

Adjustment to an inkjet printer is performed easily and appropriately. An adjustment method for performing adjustment to a printing apparatus 12 which is an inkjet printer includes: a pattern printing step of causing the printing apparatus 12 to print a test pattern; an analysis step of analyzing a result of reading the test pattern; and an adjustment step of performing an adjustment by which a result of the analysis in the analysis step is reflected in an operation of the printing apparatus 12. The printing apparatus 12 includes an inkjet head, a main scanning drive unit 112, and a head position adjustment unit 118. In the pattern printing step, a head gap is varied in the plurality of levels, and the printing apparatus 12 is caused to print the test pattern. In the analysis step, a difference in an ink landing position in a main scanning direction that occurs due to a difference in the head gap is detected based on the test pattern. In the adjustment step, the adjustment is performed based on the difference in the ink landing position.
