Introduction
Matthew Stewart Walker is an accomplished inventor based in Balmain, Australia. He has made significant contributions to the field of inkjet printing technology, holding a total of five patents. His work focuses on enhancing the performance and efficiency of printheads in inkjet printers.
Latest Patents
One of his latest patents is titled "Printhead incorporating pressure pulse diffusing structures between ink chambers supplied by same ink inlet." This innovation involves an inkjet printer that features a printhead with multiple ink chambers fed by a single ink inlet. Each chamber is equipped with a heater element that ejects drops of ink through a nozzle aperture. The design includes pressure pulse diffusing structures that mitigate the propagation of pressure waves between adjacent ink chambers. Additionally, a controller is implemented to manage print data and generate drive pulses, ensuring that the energy of these pulses increases over the printhead's lifetime.
Another notable patent is "Printhead with increasing drive pulse to counter heater oxide growth." This invention describes an inkjet printer with an array of ejection devices that release liquid drops onto a media substrate. Each ejection device contains a chamber for liquid, a nozzle, and a heater that generates vapor bubbles to eject the liquid. The controller in this printer also increases the drive pulse energy throughout the printhead's lifespan, addressing the challenges posed by heater oxide growth.
