Abstract: The present invention is a print head with nozzles of differing radii, which allows multiple drop sizes in the same print head. This can be used to weight drop sizes to achieve multi-level printing, allowing higher print quality at the same resolution. Print heads with six rows of nozzles can use the CC'MM'YK color system to attain high print quality. This system requires three differing optical densities: full optical density for yellow and black, 2/3 optical density for the most significant bits of cyan and magenta, and 1/3 optical density for the least significant bits of cyan and magenta. To achieve the various optical densities, the drop volume can be different for the various color components. A manufacturing method for print heads uses microelectronic lithographic processes on a silicon wafer, with ink channels and individual nozzles etched through the wafer. Many thousands of nozzles can be fabricated simultaneously in one print head. The radius of individual ink nozzles is determined by the mask patterns used during various lithographic processes, and nozzles with differing radii can be simultaneously fabricated without requiring extra manufacturing steps.

Abstract: Ink is contained under pressure in an ink reservoir. The ink travels to a nozzle, where it is retained in the nozzle by the ink surface tension. An equilibrium is created whereby no ink escapes the nozzle by ensuring that the ink pressure, plus a predetermined external electrostatic or magnetic field, is insufficient to expel the ink from the nozzle. The system can include a heater which is incorporated at the tip of the nozzle. When this heater is energized by a heater control circuit, the ink in contact with the nozzle tip is heated. Convection rapidly transports the heat over the ink meniscus. The ink is formulated so that surface tension reduces with increasing temperature. At an elevated temperature, the surface tension of the ink is reduced sufficiently that the equilibrium is broken, and ink moves out of the nozzle. At a predetermined time, the heater is turned off by the heater control circuit and the falling temperature causes the surface tension to increase. Ink continues to move out of the nozzle by its own momentum. Surface tension and the viscous flow limitation of the nozzle causes the ink drop to "neck" and separate from the body of ink. The ink drop then travels to the recording medium. The thermal drop on demand mechanism operates at low power, making construction of monolithic multiple nozzle print heads using a modified CMOS process practical. The print heads can include extensive fault tolerance to improve yield, device life, and reliability.

Abstract: A structure and manufacturing process for electrothermal heaters for integrated printing heads where the axes of the ink nozzles are substantially normal to the plane of the heaters, and pass substantially through the centers of the heaters. The completed heater forms a loop, with the centre of the loop being formed by the nozzle etching process. A disk of heater material is formed on the substrate. The radius of the disk is equal to the radius of hole to be etched for the nozzle, plus the required heater width. The nozzle hole is subsequently etched from the centre of the heater disk. The remaining heater material is in the form of an annulus, with the internal radius being equal to the nozzle hole radius. The structure is subsequently coated with a layer of passivation material.

Abstract: A method of and apparatus for compensating thermal printing heads which operate in drop on demand mode for the effects of power supply output resistance is disclosed. As the number of printing nozzles which are activated at any time may vary from zero to several thousand, the instantaneous resistive load variations on the power supply would normally be sufficient to cause significant drop size variations. The apparatus compensates for this variation in an accurate predictive manner. The apparatus includes a counter which provides a number representing the number of ink drops which are to be ejected during the current enable period. The output of the counter is connected to a device which determines the power supply voltage required during the enable period. This result is used to control a programmable heater power supply for the print head.

Abstract: A method of and apparatus for compensating printing heads which operate in thermal drop-on-demand printing modes for the effects of thermal lag is disclosed. The apparatus includes a counter which provides a number representing the amount of elapsed time during a heater energizing pulse as a proportion of the entire pulse duration. The output of the counter is connected to a device which determines the power supply voltage required at the said elapsed time.

Abstract: Single faults in shift registers incorporated on monolithic printing heads can render inoperable large numbers of printing actuators, as data will either be stuck high or stuck low for subsequent shift register and actuator stages. This can reduce the effectiveness of other means of fault tolerance, and increase the device sensitivity to faults in individual, normally redundant, actuators. A printing head is disclosed which provides block fault tolerance in the shift registers, limiting the effect of shift register fabrication faults to small numbers of redundant actuators. This allows a high probability of defect correction by other forms of fault tolerance integrated on the chip, thereby increasing overall device yield.
