A method for printing defect detection includes processing and analyzing a difference image obtained by comparing an image scanned with a verifier to a reference image. The detected defects are grouped, and the grouping is refined. Confidence level values are then assigned to the refined groups, and analysis is performed to determine if one or more servicing actions should be taken.

Methods, apparatuses, and systems for detecting printing defects and contaminated components of a printer

Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printer image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printer image according to verification requirements.

Method, apparatus, and system for characterizing an optical system

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.

Methods, apparatuses, and systems for batch print voiding

A verifier and printer assembly are provided. The verifier and printer assembly include a verifier module and a printer. The verifier has a magnetic docking element and the printer includes a docking portion operable to dock the verifier module. The magnetic docking element and the docking portion interact with each other to removably couple the verifier module to the printer. A magnetic attachment system for the verifier module and methods for removably coupling the verifier module and the printer for verification of a printed machine-readable symbol are also provided.

Removably couplable printer and verifier assembly

Example methods, systems, and apparatuses for verifying a printed indicium are provided. An example method may include receiving a captured image of a print media comprising the printed indicium; extracting a quiet zone grade portion from the captured image, where the quiet zone grade portion includes a printed indicium area of the printed indicium and at least one quiet zone area adjacent to the printed indicium area; in response to receiving a user input providing an overwrite quiet zone requirement indication and determining that the at least one quiet zone area does not satisfy at least one quiet zone requirement, causing at least one of adjusting the at least one quiet zone requirement to at least one reduced quiet zone requirement or adding at least one additional quiet zone area to the at least one quiet zone area.

Methods, apparatuses, and computer program products for verifying printed indicia

Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.

A method for evaluating a print quality of a printed document that is printed by a printer is provided. The printer comprises a pre-print image scanner, a post-print image scanner, and a printhead disposed between the pre-print image scanner and the post-print image scanner. The method comprises generating a pre-printing image of a print media, generating the printed document, generating a post-printing image of the printed document, generating a validation image by comparing the post-printing image with the pre-printing image, and comparing the validation image with the source image.

Methods, apparatuses, and systems captures image of pre-printed print media information for generating validation image by comparing post-printed image with pre-printed image and improving print quality

A printer-verifier system for providing print quality feedback and controlling print quality is provided. The printer-verifier system may include a printing mechanism configured to print a machine-readable indicia on a print media; a verifier device configured to optically scan the machine-readable indicia; and a print quality monitoring device in electronic communication with the printing mechanism and the verifier device.
