  • Patent number: 7926896
    Abstract: An imaging apparatus includes a controller and a media detection device mechanically engaged with a stack of print media. The media detection device has a movable indicator having a surface with distinct reflectance characteristics. A reflectance sensor is communicatively coupled to the controller. The reflectance sensor reads a reflectance of the surface and outputs a signal to the controller indicative of at least one characteristic of the print media.

  • Patent number: 6643728
    Abstract: An improved signal converter is provided to interface between an IEEE 1284 (parallel) bus or device and an IEEE 1394 (serial) bus or device. The converter in its preferred embodiment is designed for use with printers, in which the printer communicates with the converter through either the converter's 1284 port or its 1394 port. In one system, the converter acts as a “1284-to-1394 converter” to interface between a printer (on the 1394 port) and a host computer (on the 1284 port). In a second system, the converter acts as a “peer-to-peer 1394-to-1284 converter” to interface between a printer (on the 1284 port) and some type of 1394 compliant device (on the 1394 port), such as a digital camera. The converter includes a Link layer that is embedded within an ASIC, which preferably includes a microcontroller or a logic state machine, to facilitate asynchronous data transfer.

  • Publication number: 20030151634
    Abstract: A method of providing a number approximating a total number of ink drops fired by an imaging device, including the steps of incrementing a COUNT variable associated with a color of ink if an ink drop of that color is fired by a printhead in the imaging device, evaluating the value of the COUNT variable and incrementing a TOTAL INK CONSUMED variable associated with the color, dependent upon the evaluating step.

  • Patent number: 6561613
    Abstract: A method for determining a printhead misalignment of a printer. One step includes printing a printhead alignment test pattern including spaced-apart images at least partially aligned substantially along a printhead scan axis. A sensor is moved along the printhead scan axis at a known speed over the plurality of images. Sampled data points are obtained from the sensor at a known sampling rate. Another step includes determining the locations along the printhead scan axis of the edges of the images using the sampled data points, the known speed of the sensor, and the known sampling rate. An additional step includes calculating the printhead misalignment from the determined locations of the edges of the images.

  • Patent number: 6490049
    Abstract: The invention is directed to an image forming apparatus including a print engine operable in at least two modes, and an access control system connected to and controlling the print engine. The access control system includes an access control key for allowing selective and discriminate switching of the print engine from one of the at least two modes to an other of the at least two modes, such as from an economy mode to a high quality mode, or vice versa.

  • Patent number: 6172689
    Abstract: Apparatus and method controls and varies a spacing between multiple print elements, such as ink jet print orifices, in a printing system. A signal representing at least one of an advance speed of a print medium in a feed direction in the printing system and an approximate drying time of an ink after being applied to the print medium is supplied to a controller. A device, responsive to the controller, varies the spacing between at least two print elements on the basis of at least one of the advance speed of the print medium and the approximate drying time of the ink.

  • Patent number: 5971518
    Abstract: The invention is directed to a method of printing on a print medium using an ink jet printer. The ink jet printer includes a printhead assembly having a plurality of ink emitting nozzles. Ink is jetted onto the print medium from the printhead assembly during a first mode of operation using a first available set of the nozzles. Ink is jetted onto the print medium from the printhead assembly during a second mode of operation using a second available set of the nozzles, dependent upon a physical operating parameter of the ink jet printer. The second available set of nozzles has a smaller number of the nozzles than the first available set of nozzles.
