    摘要: A printhead module having a plurality of nozzles for expelling ink is provided. The printhead module has a plurality of thermal sensors. Each thermal sensor is configured to respond to a temperature at or adjacent at least one of the nozzles. The printhead module is configured to modify operation of the nozzles in response to the temperature rising above a threshold. The printhead module is a thermal inkjet printhead module and each of the nozzles includes a thermal ink ejection mechanism. Each thermal sensor comprises at least part of one of the thermal inkjet mechanisms.

    摘要: A printer is provided having a printhead of first and second elongate printhead modules and first and second printer controllers configured to receive print data and process the print data to output dot data to the printhead. The printhead modules are parallel to each other, are disposed end to end on either side of a join region, and are of different lengths. The first printer controller is arranged to output dot data to both the first and second printhead modules and the second printer controller is arranged to output dot data only to the second printhead module. One or more of the printhead modules has at least one row of print nozzles and at least two shift registers for shifting in the dot data to at least one row. Each print nozzle obtains the dot data from an element of one of the shift registers.
