    摘要： A pagewidth inkjet printer is provided having a pagewidth printhead which has a plurality of printhead modules mounted end to end on a carrier to extend across a pagewidth with each printhead module incorporating a plurality of inkjet nozzles and the nozzles of at least one of the printhead modules being rotationally displaced relative to the carrier, and a printer controller for communicating ink dot data to the inkjet nozzles in accordance with a cumulative correction factor for each printhead module. The printer controller measures the amount of rotational displacement of the rotationally displaced printhead module to determine the cumulative correction factor to at least partially compensate for the rotational displacement.

    摘要： A method of expelling ink from a printhead module is provided. The printhead module includes at least one row that has a plurality of sets of n adjacent nozzles. Each of the nozzles is configured to expel ink in response to a fire signal. The method includes providing a fire signal to nozzles at a first and nth position in each set of nozzles, and providing a fire signal to the next inward pair of nozzles in each set. In the event n is an even number, a fire signal is provided to each next inward pair until all of the nozzles in each set has been fired. In the event n is an odd number, a fire signal is provided to each next inward pair until all of the nozzles but a central nozzle in each set have been fired, and then firing the central nozzle.

    摘要： An inkjet printhead is provided having elongate printhead modules arranged to successively abut one another at respective longitudinal ends with a vertical offset and controllers for controlling the printhead modules. Each module has a plurality of ink ejection nozzles. A first controller is configured to receive and process print data to generate first ink dot data and a second controller is configured to receive and process print data to generate second ink dot data and to generate third ink dot data including the second dot data and at least some of the first dot data. The first controller is arranged to output the first dot data to at least a first printhead module and the second controller. The second controller is arranged to output the third dot data to at least a second printhead module which abuts the first printhead module.
