    摘要： A method of operating a printhead of an imaging device includes actuating a plurality of ink jets of the printhead to emit drops of ink onto an image receiving surface in accordance with a test pattern. The test pattern includes full pixel density areas and half pixel density areas that alternate in a process direction. Distances in a process direction between drops of the full pixel density areas and drops of the half pixel density areas in transition regions of the test pattern are then measured. The measured process direction distances are then correlated to a graininess level for the printhead.

    摘要： A system evaluates image quality in an image generating system in a manner that accounts for the interaction of the calibration tools used to evaluate and correct image quality in the image generating system. The system includes a test pattern generator configured to generate an image with an image generating system, an image capture device configured to generate a digital signal corresponding to the generated test pattern, an image evaluator configured to process the digital signal to detect and correct anomalies detected in the generated test pattern, a plurality of calibration tools, each calibration tool being comprised of at least one test pattern, at least one set of detection criteria, and at least one set of anomaly correction parameters, and a controller configured to select the calibration tools for operation of the test pattern generator and the image evaluator in accordance with a predetermined sequence that attenuates changes arising from application of correction parameters of one calibration tool upon a later selected calibration tool.

    摘要： A computer printer having a frame contained within a housing, a media transport and printing mechanism attached to the frame within the housing is provided with at least one debris shield positioned above the printing mechanism to protect it from falling debris. The at least one debris shield may be positioned below an air flow path generated by printer ventilation, and the printer may employ a transfer surface on which an image is generated prior to transfer to a media sheet, and above which the debris shield is positioned. Stripper fingers strip the media sheet from the transfer surface and webs between the stripper fingers form an air flow barrier to prevent debris transmission through gaps between the fingers.

    摘要： An ink stick for a phase change ink jet printer is provided. The ink stick includes a first ink stick body segment having a proximal portion and a distal portion, a second ink stick body segment having a proximal portion and a distal portion, and one or more flexible strand portions. The strand portion is formed integrally with the first ink stick body segment and the second ink stick body segment, and connects the proximal portion of the first ink stick body segment and the proximal portion of the second ink stick body segment. The strand portion flexes to permit variation in the distance between the distal portion of the first ink stick body segment and the distal portion of the second ink stick body segment.
