摘要： The invention relates to an apparatus for providing information to a printer controller in order to identify the type of printer cartridge installed in a thermal ink jet printer. The apparatus includes a printer cable containing a set of electrically-conductive wires connected to contacts in a printer cable connector. The contacts of the printer cable connector make physical connection to an identification circuit on the printer cartridge. The identification circuit includes an electrical conductor which is at an electrical reference potential. When none, or one or more contacts on the cable connector are in electrical contact with the electrical conductor of the identification circuit, a signal corresponding to the identification of the printer cartridge is produced which is used by the printer controller to determine the type of printer cartridge installed in the printer. Selective contact between the connector contacts and the identification circuit, so as to produce an electrical code, may be obtained using a label having apertures, contact pads, electrical traces, or a combination thereof. Accordingly, various cartridge identification codes can be produced using various methods which allow encoding of the information on a cartridge during or after the manufacture of the cartridge body is substantially complete.

摘要： The invention described in the specification relates to an apparatus for supplying electrical information to a printer controller in order to identify the one or more cartridges installed in a printer. The apparatus comprises a carriage which is laterally translatable relative to the movement of print media through the printer, carriage translation means, and a replaceable cartridge attached to the carriage. The apparatus further comprises an indicia device which is attached to the replaceable cartridge and which has optically readable indicia thereon containing encoded information which contains information identifying the type of cartridge installed in the printer. The apparatus also includes an optical code reader which reads and transmits the encoded information to a printer controller as the cartridge moves in a lateral direction relative to the code reader. The invention thus uses the linear motion of the carriage in combination with the optically readable indicia device on the cartridge to identify the type of cartridge, or to otherwise control the printer depending on the specific information provided by the indicia device.

摘要： An ink jet printing apparatus forms a printed image on a print medium based on image data. The apparatus includes an ink jet print head having ink ejection nozzles in a nozzle array. Ink is ejected from the nozzles and onto the print medium as the print head scans across the print medium in a scan direction, thereby forming the image on the print medium. The nozzle array on the print head includes a first substantially columnar array of nozzles aligned with a print medium advance direction which is perpendicular to the scan direction. The first array has a first upper subarray pair that includes a first upper left and a first upper right subarray of nozzles. The first upper left and a first upper right subarrays each include a substantially linear arrangement of n number of nozzles having equal nozzle-to-nozzle spacings. The nozzle-to-nozzle spacing in the first upper right subarray is equivalent to the nozzle-to-nozzle spacing in the first upper left subarray. The first upper right subarray is offset from the first upper left subarray in the scan direction by a first horizontal spacing, and is offset in the print medium advance direction by one-half of the nozzle-to-nozzle spacing. The nozzle array also includes a second substantially columnar array of nozzles aligned with the print medium advance direction. The second array is offset from the first array in the scan direction by a second horizontal spacing, and is offset in the print medium advance direction by one-fourth of the nozzle-to-nozzle spacing. The second columnar array has a second upper subarray pair that includes a second upper left and a second upper right subarray. The second upper left and second upper right subarrays each include a substantially linear arrangement of n number of nozzles having equal nozzle-to-nozzle spacings. The second upper right subarray is offset from the second upper left subarray in the scan direction by the first horizontal spacing and in the print medium advance direction by one-half of the nozzle-to-nozzle spacing.

摘要： An ink jet print head has first nozzles of a first diameter for ejecting droplets of ink having a first mass, and second nozzles of a second diameter for ejecting droplets of ink having a second mass. The first diameter is larger than the second diameter, and the first mass is larger than the second mass. First and second heater-switch pairs are connected in parallel on a substrate of the print head. The first heater-switch pairs include first heaters adjacent corresponding first nozzles, and the second heater-switch pairs include second heaters adjacent corresponding second nozzles. The first and second heaters are composed of electrically resistive material occupying first and second heater areas on the substrate. The first heater-switch pairs also include first switching devices connected in series with the first heaters, with each first switching device developing a first switching device voltage drop as a first electrical current flows through. The second heater-switch pairs include second switching devices connected in series with the second heaters, with each second switching device developing a second switching device voltage drop as a second electrical current flows through. The first heater area is larger than the second heater area, thus matching heater area to nozzle diameter to provide for more efficient transfer of thermal energy to the ink. The voltage drop across each first switching device is substantially equivalent to the voltage drop across each second switching device, thus reducing undesirable nozzle-to-nozzle variations in the amount of energy delivered to the ink.

摘要： A thermal inkjet apparatus includes a printhead body, nozzles, ink cavities and ink supply lines. Heater resistors are in the cavities and a firing circuit is connected to provide firing pulses to the heater resistor and nucleate the ink so that it fires ink out of the nozzles. Each heater resistor is also connected to a warming circuit that supplies warming pulses, one warming pulse during each firing cycle, to warm the heater resistors but not nucleate the ink. The warming circuit includes current limiting ballast resistors to limit the current through the healer resistors and thereby prevent the warming pulse from nucleating the ink. Warming pulses and firing pulses are not generated during the same firing cycle for a particular heater resistor. One or more thermal sensors are disposed on the printhead body to sense the temperature and a control circuit responds to the sensors to generate warming pulses having desired widths to provide a desired level of warming. By wide range pulse width modulation of the warming pulse, the warming effect of the warming pulse may be increased or decreased as desired. Also the warming pulse may be completely eliminated, such as by pulse width modulating the pulse to have a zero duration.

摘要： An inkjet printhead heater chip has an ink via asymmetrically arranged in a reciprocating direction of inkjet printhead movement. The ink via has two sides and a longitudinal extent substantially parallel to a print medium advance direction. A column of fluid firing elements exists exclusively along a single side of the two sides. The heater chip and ink via each have a centroid and neither resides coincidentally with one another. Preferably, the heater chip centroid resides externally to a boundary of the ink via. In other aspects, the column of fluid firing elements can be a sole column or plural and may be centered in the reciprocating direction. The ink via can be a sole via or plural. The heater chip can be rectangular and the ink vias can be closer to either the long or short ends thereof. Inkjet printers for housing the printheads are also disclosed.

摘要： An ink jet printer includes a printhead control circuit that produces printhead command signals based on data signals provided by the printer. A power circuit actuates ink ejectors in response to the printhead command signals and includes a plurality of compensation circuits. Each ink ejector is associated with a single compensation circuit and each compensation circuit includes a number of switches connected in parallel with each other. Each switch in a single compensation circuit is connected to actuate a single ink ejector when the switch is turned on. The compensation circuits adjust their internal resistance by turning on more or less switches and thereby compensate for changing effective parasitic resistance of the power lines.
