Abstract: An encoding system is described for a media handling system including an endless belt. The encoding system includes encoding indicia associated with the endless belt. A first encoder transducer is responsive to the encoding indicia to provide a first encoder signal. A second encoder transducer is responsive to the encoding indicia to provide a second encoder signal, the second encoder transducer spatially separated from the first encoder transducer. An encoder processor is responsive to the first encoder signal and the second encoder signal to determine position data regarding the endless belt. Interruption of indicia due to a belt seam is accommodated by transferring belt position calculation from one transducer to the other as the seam passes between the two transducers. The processor is adapted to compensate for variations in the encoder indicia pitch caused by belt temperature differentials.

Abstract: An embodiment of a thermal drop detector in accordance with the present invention includes an array configured to define a plurality of cells each of which is configured to detect thermal changes in an area of that cell resulting from deposition of a drop adjacent that cell. This embodiment of a thermal drop detector additionally includes a thermally conductive layer over each of the cells to protect each of the cells from physical contact with the drop. A method of thermal drop detection in accordance with the present invention includes depositing a drop on a thermally conductive material, the thermally conductive material overlaying a thermally sensitive array. The method additionally includes measuring via the thermally sensitive array a thermal change resulting from deposition of the drop on the thermally conductive material. The method further includes determining a characteristic of the drop deposited on the thermally conductive material based upon the thermal change measured by the thermally sensitive array. Further characteristics and features of the thermal drop detector and method of thermal drop detection are described herein, as are various exemplary alternative embodiments.

Abstract: A detection system for detecting the size of a print medium. A hollow tube is positioned adjacent the paper or print medium. An ultrasonic transducer apparatus launches pulses of ultrasonic energy into the tube, and is responsive to ultrasonic echoes of the pulses to convert echo pulse energy into electrical detected signals. A flag positioning apparatus selectively positions a blocking flag within the tube at a location spaced from the transducer apparatus which is indicative of a print medium size. A controller responds to the electrical detected signals to determine a print medium size. The flag positioning apparatus can provide a single flag movable along a longitudinal extent of the tube, or a set of flags spaced along the longitudinal extent, one or more of which are selectably deflected by the print medium.

Abstract: A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

Abstract: An indexing stop is moveable relative to a printer carriage that carries cartridges for printing a swath at a time. Part of the stop is in the path that the carriage travels. The stop is advanced while the cartridges print one, "first" swath (that is, while the carriage is stationary). The stop is advanced to a position corresponding to the location where the carriage is to be moved to facilitate printing of the next, "second" swath. Once the first swath is printed, the carriage is controlled to move toward and abut the stop, thus arriving in the location for printing the second swath. The stop simplifies and speeds the carriage movement between swaths, thereby increasing printer throughput.

Abstract: Carriage and paper motion overlap method and apparatus are described. The preferred method utilizes carriage ramp-down and unidirectional, constant-speed periods of time to advance paper via the printer's paper advancement mechanism while avoiding current-intensive ramp-up periods of time during which demands on the printer's power supply are high. The printer's controller is programmed to implement preferably concurrently operable processes one of which controls paper movement and the other of which controls carriage movement. The processes signal one another based upon their monitoring of defined conditions of the printer and the print buffer, and by setting and clearing a flag.

Abstract: In one example, an encoding station of a printing system forms a pattern of non-printed features onto flowing print media. The non-printed features are detected, and timing signals generated from the detected features. The timing signals cause the media to be printed at a desired resolution in the direction of the flow.

Abstract: Overall print quality is improved via a method whereby an actual image is printed, a virtual image is defined based on image data, and the actual and virtual images are compared to identify a printhead error pattern which may be used to correct subsequent printing errors. This typically is accomplished via a system which employs an optical device which views an actual image to produce optical data, and a controller which derives a virtual image from image data provided to the printhead. The controller then compares the actual and virtual images to identify an error pattern, and modifies subsequent image data to compensate for perceived errors.
