Abstract:
An image sensing and printing device includes a housing. An area image sensor is positioned on the housing for sensing a viewed image to be printed on media and for generating pixel data representing the viewed image. A printing mechanism is arranged on the housing. The printing mechanism defines a media feed path and includes a printhead assembly that includes a pagewidth printhead having at least one printhead chip that spans the media feed path. A feed mechanism feeds media along the media feed path so that the printhead can carry out a printing operation on the media. A processor is positioned in the housing. The processor includes processing circuitry. An image sensor interface is connected to the processing circuitry for receiving pixel data from the image sensor, converting the pixel data into an internal format and writing the converted pixel data to the processing circuitry. The processing circuitry is configured to convert the pixel data to print image data. A printhead interface is connected to the processing circuitry for receiving the print image data from the processing circuitry and for providing signals representing the print image data to the printhead so that the printhead can carry out the printing operation to generate a printed representation of the viewed image.

Abstract:
The current invention provides for a nozzle arrangement for an inkjet printer. The nozzle arrangement includes a wafer substrate defining an ink supply channel therethrough, with side wall portions and a top wall portion arranged on the wafer substrate to define a nozzle chamber for operatively receiving ink, said top wall portion defining an ink ejection port and a plurality of etchant holes therein of sufficient diameter such that surface tension effects restrict ink being ejected from the chamber via the etchant holes. The nozzle arrangement also includes a thermal actuator cantilevered on the wafer substrate so that the actuator partitions the nozzle chamber, the actuator having a heater layer which produces thermal expansion of said actuator upon activation, thereby ejecting ink from the nozzle chamber via the ejection port.

A drive circuitry layer is positioned on the substrate, the substrate and the drive circuitry layer defining a plurality of ink inlet channels. Nozzle chamber walls and roofs spanning the nozzle chamber walls are positioned on the substrate to define nozzle chambers in fluid communication with respective ink inlet channels, the roofs defining respective ink ejection ports.

Thermal actuators are outside of and associated with respective nozzle chambers and are connected to the drive circuitry layer to move with respect to the substrate on receipt of electrical signals from the drive circuitry layer. Each effort formation is fast with a respective thermal actuator such that reciprocal movement generated by the thermal actuators results in reciprocal movement of the ink ejection members and subsequent ink drop ejection from the ink ejection ports.
