摘要:
A printhead having a plurality of rows of nozzles is provided. The nozzles in each row are grouped into fire groups. The printhead is configured to sequentially fire, for each row, the nozzles of each fire group, such that each nozzle in the sequence from each fire group is fired simultaneously with respective corresponding nozzles in the sequence in the other fire groups.
摘要:
An inkjet printer is provided having a printhead having inkjet nozzles and a plurality of controllers configured to process print data for printing and to output the processed data to the printhead. The plurality of controllers are connected to a common input of the printhead.
摘要:
A printhead module capable of printing a maximum of n of channels of print data, the printhead being configurable into: a first mode, in which the printhead is configured to receive print data for a first number of the channels; and a second mode, in which the printhead is configured to receive print data for a second number of the channels, wherein the first number is greater than the second number.
摘要:
A print engine is provided which has a printhead capable of printing a maximum of n channels of print data and a controller. Each channel is associated with rows of printing nozzles of the printhead. The controller controls the printhead to print in: a first mode, in which the printhead receives from the controller, print data for a first number of the channels; and a second mode, in which the printhead receives from the controller, print data for a second number of the channels less than the first number and dummy data for a portion of each nozzle row associated with the remaining number of the channels. The first number is less than n.
摘要:
A method of expelling ink from a printhead module including at least one row that comprises a plurality of adjacent sets of n adjacent nozzles, each of the nozzles being configured to expel ink in response to a fire signal, the method comprising providing, for each set of nozzles, a fire signal in accordance with the sequence: [nozzle position 1, nozzle position n, nozzle position 2, nozzle position (n−1), . . . , nozzle position x], wherein nozzle position x is at or adjacent the centre of the set of nozzles.
摘要:
A printhead is provided having a plurality of rows of nozzles, with the nozzles in each row being grouped into fire groups, and a controller configured to fire the nozzles of each fire group by outputting firing pulses to the nozzles. The controller sets the number of fire groups in each row based on the width of the firing pulses and a predetermined length of time for firing all of the nozzles of that row.
摘要:
A printhead having at least first and second rows of print nozzles. Each nozzle has first circuitry of a first type arranged asymmetrically to second circuitry of a second type. The respective positions of the first and second circuitry of each nozzle of the first row are arranged mirrored with respect to the first and second circuitry of each nozzle of the second row.

摘要:
A printhead is provided which has a plurality of rows of print nozzles. Each row has first and second drive circuitry for each nozzle respectively positioned at opposite sides of each nozzle with respect to the row. The respective positions of the first and second circuitry of each nozzle of each row are rotated 180 degrees relative to the respective positions of the first and second circuitry of each nozzle in each adjacent row.
摘要:
A printhead integrated circuit including a MEMS layer having a plurality of nozzle assemblies and a CMOS layer having control circuitry. Each nozzle assembly includes a heater element for ejecting ink and sensing a temperature of the nozzle assembly. The control circuitry modifies operation of the heater elements in response to a sensed temperature exceeding a predetermined threshold.
