An inkjet printer is provided, which is configured to acquire gap information related to a gap between an ink discharging surface and a recording sheet in each individual position of top-formed positions and bottom-formed positions within a predetermined wave-shape generating range, identify, when the predetermined wave-shape generating range includes a partial range in which the recording sheet is not placed, a top-formed position where the gap information has not been acquired and a bottom-formed position where the gap information has not been acquired, within the partial range, complement the unacquired gap information in the identified top-formed position with a value determined based on the respective pieces of gap information acquired in other top-formed positions, and complement the unacquired gap information in the identified bottom-formed position with a value determined based on the respective pieces of gap information acquired in other bottom-formed positions.

In a processing apparatus, with an inkjet print head, that processes individual items, a drive motor that operates a transport mechanism to transport the individual items in the x-direction of a Cartesian coordinate system past the inkjet print head in a printing position so as to execute a printing operation with the inkjet print head on each individual item. The drive motor arrangement also moves the inkjet print head in the y-direction into a first position that is any of an exchange position, the printing position, a cleaning position or a sealing position. The drive motor arrangement also moves the inkjet print head vertically, in the z-direction of the exchange position or the sealing position, into at least one other position that is either the printing position or the cleaning position.

An apparatus with an ink printing device generates imprints on items moving in a transport direction. The ink printing device displaces the ink cartridge, which is a single inkjet print head of at least 1 inch in width transverse to the transport direction, as well as in a vertical direction, and counter to the vertical direction. A movement mechanism of the printing module is provided to vertically raise and lower the inkjet print head. The movement mechanism has a mechanism for motorized movement of the inkjet print head, and a mechanism for manual displacement in the vertical direction.

A printing device includes a housing having at a bottom surface thereof a print head in which printing elements are arrayed linearly in a main scanning direction, a detector configured to detect a movement distance of the housing in a sub-scanning direction, an inputter configured to input an instruction to start printing, an indicator disposed on an edge portion of the housing and configured to indicate a planned print position on a printing medium, and a processor. The processor is configured to determine whether the housing has been moved in the sub-scanning direction by a standard distance between the indicator and the print head in the sub-scanning direction after inputting by the inputter of the instruction to start printing, and cause the print head to start printing at a start printing position that is a position to which the housing has been moved in the sub-scanning direction by the standard distance.

A printing device including: a print head which performs printing on a printing area in a first nail of a finger or a toe and next performs printing on a printing area in a second nail of a finger or a toe; a mover which moves the print head; and a processor. The processor sets a printing start position in the second nail in response to a printing end position of the printing area in the first nail, the printing start position in the second nail being at a side closer to either a nail tip-side end or a root-side end of the printing area in the second nail, and controls the print head and the mover to perform the printing on the printing area in the second nail from the printing start position in the second nail after the printing is finished for the first nail.

This application relates to an inkjet printing apparatus. In one aspect, the apparatus includes a main frame and a flat-bed moving in a first direction with respect to the main frame. The apparatus may also include a first printing device located on a movement path of the flat-bed and comprising a first inkjet head for jetting base ink onto a print area of the print medium. The apparatus may further include a second printing device located on the movement path of the flat-bed and comprising a second inkjet head for jetting activator ink onto the print area of the print medium onto which the base ink is jetted. The apparatus may further include at least one processor electrically connected to the flat-bed, the first printing device, and the second printing device and configured to control operations of the flat-bed, the first printing device, and the second printing device.

An inkjet recording apparatus and an inkjet recording method are provided that facilitate designing of units for subsequent treatment in terms of their shapes and/or positions, while suppressing variability in image quality resulting from subsequent treatment. Two or more recording heads are disposed in a staggered arrangement in X and Y directions. The paired units for subsequent treatment are disposed in parallel to each other along the X direction, and the recording heads are interposed between these units. The length of each of the units for subsequent treatment in the X direction is greater than or equal to the ink-dischargeable extent in the X direction of the recording heads in one scan. The recording heads are arranged, so that nozzle groups, from which the droplets of the same color are discharged, are disposed symmetrically with respect to an intermediary line between the paired units for subsequent treatment.

An ink-jet head protection device used in a building area having accumulated powder is provided. The ink-jet head protection device includes a movable base and an airflow guiding mechanism. The movable base includes an ink-jet head base. The ink-jet head base includes one or more ink-jet heads. The ink-jet head is arranged corresponding to the building area. The airflow guiding mechanism is assembled to the movable base. The airflow guiding mechanism generates a dust separating airflow and includes an airflow opening for guiding the dust separating airflow flowing between the ink-jet head and the building area. The dust separating airflow is used to isolate the powder spilled from the building area. Accordingly, the airflow guiding mechanism generates the dust separating airflow flowing between the ink-jet head and the building area.

An inkjet product coding printing system comprises a plurality of printing objects comprising a travel direction and a printing surface arranged vertically; at least one inkjet printer head, wherein the inkjet printer head further comprises a plurality of ink nozzles facing the printing surface of the plurality of printing objects, wherein the plurality of ink nozzles is arranged in a plurality of rows configured along the travel direction of the plurality of printing objects, wherein the inkjet printer head can move up and down vertically, wherein the inkjet printer head moves orthogonally to the travel direction of the plurality of printing objects when the inkjet printer head ejects an ink; a motion unit connected with the inkjet printer head; and at least one control system controlling the motion unit and the inkjet printer head, and a method of printing product coding information by the inkjet product coding printing system.

One embodiment relates to a liquid discharge head substrate including at least one heat generating resistive element, a first insulating layer covering the heat generating resistive element, a conductive layer disposed on the first insulating layer and overlapping the heat generating resistive element with the first insulating layer interposed therebetween in a plan view with respect to an upper surface of the heat generating resistive element, and a second insulating layer covering an edge of the conductive layer. The edge of the conductive layer has a tapered shape.
