  • Publication number: 20240086664
    Abstract: Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.

  • Publication number: 20230415506
    Abstract: Various methods and systems for a printer having verifiers are disclosed herein. Such methods provide for voiding a printed media in a batch printing run. The methods further correspond to identifying the printed media that is printed as part of the batch printing run as a failed media in an instance an assigned grade fails to satisfy a predetermined threshold, marking the printed media as a failed printed media, determining whether the batch print run is in sequential mode or non-sequential mode, marking the one or more subsequently printed media as additional failed printed media, and reprinting the failed media in sequence after one or more subsequently printed media before continuing the batch printing run if the batch print run is in sequential mode.

  • Patent number: 11468277
    Abstract: Printers capable of determining a media type of a media and associated methods are provided. An example method includes scanning a media with a verifier associated with the printer to generate at least two consecutive windows of the media. The example method further includes determining a vertical length of a captured image based on a comparison of image characteristic values captured in the at least two consecutive windows. The example method further includes determining a media characteristic associated with the media based at least on the captured image and the vertical length and one or more stored media profiles. The example method further includes calibrating the printer based on the media characteristic.
