Abstract:
The present invention relates to an ink ejection integrated circuit (IC) for a printhead. The IC includes rows of elongate nozzle arrangements. Each nozzle arrangement defines an ink ejection port at one end and has an internal cantilevered actuator anchored at the other end so that the actuator can move to eject ink out though the ink ejection port. The rows are arranged in pairs with the ports of one of the rows being proximally located to the ports of the other row, for each pair.
Abstract:
The current invention provides for an inkjet printhead for an inkjet printer. The inkjet printhead includes a wafer substrate defining an ink supply channel. Side wall portions extend away from one surface of the wafer substrate, and a nozzle layer supported on the side wall portions and extending parallel to said one surface of the wafer substrate. The nozzle layer and the side wall portions define an array of nozzle chambers for receiving ink. The nozzle layer defines ink ejection ports and etchant holes. The etchant holes are of sufficient diameter to retain ink in the nozzle chamber by surface tension. Each nozzle chamber has a thermal actuators cantilevered on the wafer substrate. The actuator partitions the nozzle chamber and has a heater layer which produces thermal expansion of said actuator upon activation.

Provided is a printing cartridge for a printer. The cartridge includes an upper and a lower molding configured to engage cooperatively to define a chamber, and a hollow cylindrical former with print media rolled thereon to form a print medium roll. The cartridge also includes an ink cartridge in the form of a cylindrical container internally divided into ink reservoirs, said ink cartridge co-axially rotatable inside the former, as well as an elastomeric seal molding configured to arrange the ink reservoirs in fluid communication with a printhead of the printer.
Abstract:
A printhead is provided for an inkjet printer. The printhead includes a wafer assembly supporting rows of ink ejection nozzles. Each nozzle includes a nozzle structure defining a nozzle chamber in fluid communication with an ink ejection port. A cantilevered thermal actuator terminates in a free end over an ink supply channel. The thermal actuator includes a serpentine heater layer connected to a CMOS drive circuitry layer of the wafer assembly. The CMOS drive circuitry layer is configured to actuate the thermal actuator and reciprocate the actuator to eject ink in the nozzle chamber out through the ink ejection port.
Abstract:
An image processing apparatus for applying desired effects to a stored image. The apparatus comprises an optical reader; a feed mechanism for feeding a card having an array of dots past the optical reader; an optical reader interface that is connected to the optical reader, the optical reader interface able to control the optical reader to detect a data area on the card, to detect a bit pattern corresponding to the array of dots in the data area, and to produce raw data from the bit pattern while the card is being fed past the optical reader, the raw data used to produce an image processing script; and, a processor that is connected to the optical reader interface to receive and apply the image processing script to the stored image to generate an output image with the desired effects. The array of dots defines a first resolution and the optical reader has a sensor with a second resolution at least twice the first resolution. The optical reader has a length such that an insertion rotation of the card by the feed mechanism of up to 1 degree is accommodated.
