    摘要： A printer having of a printhead having first and second elongate printhead modules, the printhead modules being parallel to each other and being disposed end to end on either side of a join region, wherein the first printhead module is longer than the second printhead module. At least first and second printer controllers configured to receive print data and process the print data to output dot data for the printhead, wherein the first printer controller outputs dot data to both the first printhead module and the second controller; and the second printer controller outputs dot data to the second printhead module, wherein the dot data output by the second printer controller includes dot data it generates and at least some of the dot data received from the first printer controller.

    摘要： A printer is provided which has a printhead integrated circuit having a row of aligned printhead nozzles and a controller for supplying data to the printhead integrated circuit. A sequential group of the nozzles at one end of the printhead integrated circuit are offset from the other nozzles of the row. The printer controller is configured to control order and timing of the supplied data to compensate for the offset nozzles during printing.

    摘要： Provided is a printhead integrated circuit for an inkjet printer that has a nozzle and a corresponding actuator for ejecting ink through the nozzle. The Printhea IC also has drive circuitry for controlling the operation of the actuator. The drive circuitry has an open actuator test circuit comprising an open actuator test input, a column enable input and a row enable input, a drive transistor operatively linking said actuator to a power supply, a bleed transistor arranged in parallel with the actuator, a sense transistor operatively linking an output of the drive transistor and inputs of the actuator and bleed transistor to a sensing node. Actuating the actuator to eject ink by enabling the column and row enable inputs, deactivates the bleed transistor and activates the drive transistor to link the actuator to the power supply. Testing the actuator involves enabling the open actuator test input to activate the sense transistor, so that the actuator is short-circuited and the sense node is pulled high if the actuator is open-circuit.

    摘要： Provided is test circuitry for testing a thermal actuator of a printhead nozzle arrangement of a printhead. The circuitry includes an open actuator test input, a column enable input and a row enable input.

The circuitry also includes a sense transistor operatively linking an output of the drive transistor and inputs of the thermal actuator and bleed transistor to a sensing node, as well as a controller configured to deactivate the bleed and sense transistors and to activate the drive transistor when the column enable and row enable inputs are activated to link the thermal actuator to the power supply, and to activate the bleed and sense transistors when the open actuator test input is activated, so that the thermal actuator is short-circuited and the sense node is pulled high if the thermal actuator is open-circuit.
