    摘要： A method and apparatus for detecting the absence of print media in an imaging device, such as a printer. The printer includes a print mechanism, a media tray for supplying sheets of print media to the printer, and a pick mechanism for moving the sheets of print media from the media tray to the print mechanism. The pick mechanism includes a pick roller, a pick motor that rotates the pick roller, and a controller in communication with the pick motor. Rotating the pick roller when there are no sheets of print media in the media tray causes the pick motor to stall. The controller produces a signal when the motor stalls indicating to the user that the printer is out of print media. A rotational position encoder coupled to the pick mechanism and in communication with the controller can be used to provide pick motor stall detection.

    摘要： Methods and systems are provided for compensating for media indexing errors in a printing device. In one embodiment, the method comprises identifying a desired amount by which the print receiving medium should be indexed in order to print at the next location for the image being printed. The method further comprises determining an ideal indexing command for causing the indexing command based upon a compensation factor in order to compensate for imperfections in the indexing system. In this embodiment, the ideal indexing command is adjusted only once per indexing of the print receiving medium by the desired amount, and the adjusted ideal indexing command is utilized to move a roller and to index the receiving medium by the desired amount in order to print at the next location for the image being printed.

    摘要： Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image. An inkjet printhead of the printer has a plurality of fluid firing actuators arranged in a substantial column. A controller communicates with the printhead to identify active actuators given to fire at a particular time during use to print the image. However, to prevent unsightly print quality from occurring during overlapping adjacent print swaths, for example, certain of the identified actuators are prevented from firing. Especially, actuators in the column further from a center of the column fire less frequently than those closer to the center. A position sensor is also used to locate the printhead relative to the image. The controller correlates the position to the printhead and actuators and fires the active actuators or not.

    摘要： A method for providing a virtual replenishing of a supply item with an imaging substance includes the steps communicating to a database a first serial number associated with a first supply item; comparing the first serial number with a plurality of serial numbers stored in the database; receiving from the database one of a first data indicating non-correspondence between the first serial number with one of the plurality of serial numbers and a second data indicating correspondence between the first serial number with one of the plurality of serial numbers, wherein the second data includes a verification key; and if the verification key corresponds to the first key stored in the memory associated with the first supply item, then performing the step of allocating at least a portion of a surplus amount of the imaging substance contained in the first supply item for use.
