Abstract: A wafer structure is disclosed and includes a chip substrate and a plurality of inkjet chips. The chip substrate is a silicon substrate fabricated by a semiconductor process on a wafer of at least 12 inches. The inkjet chips include at least one first inkjet chip and at least one second inkjet chip directly formed on the chip substrate by the semiconductor process, respectively, and the plurality of inkjet chips are diced into the at least one first inkjet chip and the at least one second inkjet chip for inkjet printing. Each of the first inkjet chip and the second inkjet chip includes a plurality of ink-drop generators produced by a semiconductor process and formed on the chip substrate. Each of the ink-drop generators includes a thermal-barrier layer, a resistance heating layer, a conductive layer, a protective layer, a barrier layer, an ink-supply chamber and a nozzle.

Abstract: In example implementations, a system is provided. The system includes at least one fluid ejection apparatus, a heater and an energy source. The at least one fluid ejection apparatus dispenses a de-contented fluid onto a substrate during conveyance of the substrate. The heater is arranged after the at least one fluid ejection apparatus along a substrate conveying path. The heater removes a liquid from the de-contented fluid on the substrate such that the particles of the de-contented fluid remain on the substrate. The energy source is arranged after the heater along the substrate conveying path. The energy source applies energy to the substrate during the conveyance of the substrate to heat the substrate to a temperature that is approximately a melting temperature of the substrate to fuse the particles on the substrate to the substrate.

Abstract: An image forming apparatus includes a rotational conveying unit for conveying a recording medium by rotating about a rotational axis. A head unit includes n nozzle rows in a conveying direction perpendicular to an axial direction parallel to the rotational axis. Each of the n nozzle rows includes nozzles aligned as a nozzle row in the axial direction. Each n nozzle row is arranged at a distance of d1 to d(n−1) from a predetermined reference nozzle row. A circuit outputs a rotational amount detection signal, and a conveying amount detection signal, and generates a discharge synchronization signal based on the detected rotational amount detection signal and the detected conveying amount detection signal, then generates a nozzle row timing signal based on the distance of the d1 to d(n−1) and the discharge synchronization signal, and generates discharge data based on the discharge synchronization signal and the nozzle row timing signal.
