Abstract: A liquid droplet jetting apparatus includes: a carriage configured to scan in a main scanning direction; a jetting head installed in the carriage, having nozzles arranged in a sub scanning direction intersecting with the main scanning direction, and configured to jet liquid droplets from the nozzles; a conveyer configured to convey the recording medium in the sub scanning direction; and a controller configured to control the carriage, the jetting head and the conveyer. The nozzles form nozzle groups including two nozzle groups adjacent in the sub scanning direction; and the controller is configured to execute a predetermined printing mode in which a pass printing and conveyance of the recording medium in the sub scanning direction are alternately performed. The pass printing causes the carriage to move one time in the main scanning direction while jetting the liquid droplets from the nozzles.

Abstract: Backing material is passed by a first heater to pre-heat the backing material. The backing material is then passed by a printing engine to print marking material on the backing material, and passed by a first light source to apply ultra-violet (UV) light to the marking material printed on the backing material, to partially cure the marking material. Further, the backing material is passed by a container to expose the partially cured marking material to adhesive particles to cause the adhesive particles to adhere only to the marking material. The backing material is passed by a second light source to apply additional UV light to the marking material partially cured on the backing material to fully cure the marking material. Finally, the backing material is passed by a second heater to melt the adhesive particles that are adhered to the marking material on the backing material.
Abstract: A liquid discharging apparatus includes a plurality of dischargers that discharge a liquid, a determination portion that determines discharge states of the liquid in the dischargers, and a controller that controls the plurality of dischargers, in which, in a case in which the determination portion determines that the discharge state of the liquid in one discharger is abnormal, the controller controls the plurality of dischargers so as to cause the liquid to be discharged from another discharger instead of causing the liquid to be discharged from the one discharger until a predetermined time has elapsed since determination, and controls the plurality of dischargers so that a repair operation, which repairs the discharge state of the liquid in the one discharger to normal, is caused to be executed after the predetermined time has elapsed since the determination.
Abstract: A liquid discharge apparatus includes: a nozzle plate having a plurality of nozzles; a pressure chamber communicating with the nozzle; and a pressure generating element, in which each of the nozzles is formed by communicating a first opening portion and a second opening portion, when two nozzles adjacent to each other are represented by a first nozzle and a second nozzle, the second opening portion of the first nozzle and the second opening portion of the second nozzle are disposed along a first direction, each of the second opening portions extends in a second direction, and an inner diameter of the second opening portion in the second direction is larger than an inner diameter of the first opening portion, the first opening portion of the first nozzle and the first opening portion of the second nozzle are disposed so as to be shifted from each other in the second direction.
Abstract: A pressure chamber of each of channels of an inkjet head has a non-rotating body shape around an axis perpendicular to a support substrate on which the pressure chamber is formed. The direction of the pressure chamber corresponding to a rotation angle from a reference position around the axis passing through the pressure chamber is defined as the direction of the pressure chamber. A plurality of channels arranged in a same row in a direction parallel to the substrate includes channels and having the pressure chamber facing different directions. In a same row, channels (e.g. channel 21a1) driven by a same circuit element (e.g. circuit element) are arranged such that the pressure chambers face a same direction.
