摘要： An inkjet printer head includes a substrate having a manifold and an ink channel to supply ink, a nozzle plate formed on the substrate, a chamber formed between the substrate and the nozzle plate and extending toward the substrate and the nozzle plate, an electrode formed at an interface between the substrate and the nozzle plate and around the chamber, and a heater having both ends extending in contact with the electrode to be suspended on the chamber in direct contact with the ink and to generate bubbles from both surfaces thereof. The inkjet printer head is capable of improving manufacturing process efficiency by omitting a process of separately forming a heater passivation layer, operating the heater at low electric power by omitting the heater passivation layer, improving integrity of a nozzle by lowering a working voltage, and improving reliability in manufacturing processes by locating the suspended heater to be in parallel with the substrate and the electrode.

摘要： An ink jet image forming apparatus includes a reset correction unit to restrict a heater driving time so as to prevent a heater from being damaged due to overheating when an error occurs in a system clock. The reset correction unit may determine that an error occurs in the system clock if a discharging voltage of at least one charging circuit, which performs a charging operation using the system clock, is decreased to a reference voltage. In this case, the reset correction unit can generate a reset signal having an initial state such that the heater is no longer driven.

摘要： A method of fabricating a high efficiency inkjet print head includes forming an oxide film on a surface of a substrate, sequentially forming and patterning a heater layer and a wiring layer on the oxide film, forming a passivation layer on the heater layer and the wiring layer and patterning the passivation layer so that a heater is exposed, etching the substrate to form restrictors at both sides of the heater, forming a chamber layer on the passivation layer, forming a sacrificial layer on the chamber layer and polishing the sacrificial layer, forming a nozzle layer on the chamber layer, forming an ink-feed hole at a bottom surface of the substrate, and removing the sacrificial layer. The inkjet print head is capable of reducing energy consumption by fabricating a heater having high efficiency, and capable of maintaining good heating characteristics since an original temperature of the inkjet print head is rapidly recovered after the heater is instantly heated and electric current is not supplied. In addition, since the heater is mounted on the substrate, the inkjet print head can maintain structural integrity, and since the heater is formed in a planar shape without bent portions, the heater can be formed to a uniform thickness.

摘要： An inkjet print head with a high efficiency heater includes a substrate having an ink-feed hole extending therethrough to receive ink stored in a cartridge, a flow path layer to define an ink chamber in fluid communication with the ink-feed hole, a nozzle plate having a nozzle to discharge the ink from the ink chamber to an exterior, a heater located adjacent to an inner wall of the ink chamber and disposed in contact with the ink in the ink chamber, and a lead electrically connected to the heater. The heater increases thermal efficiency and maintains a stable structure. In addition, since the heater is disposed adjacent to the inner wall of the ink chamber, the heater is barely affected by the ink supply pressure or the cavitation force that results from ink bubbles shrinking.
