1. A method of automatically diagnosing one or more media handling defects on a sheet subjected to one or more printer conveyance operations, the method comprising:
processing the sheet to subject the sheet to one or more printer conveyance operations;
receiving a first image of the sheet subjected to the one or more printer conveyance operations;
analyzing the first image to determine whether a media handling defect is present on the processed sheet as a result of the one or more printer conveyance operations;
where it is determined that a media handling defect is present on the processed sheet as a result of the one or more printer conveyance operations, comparing the detected media handling defect on the sheet subjected to the one or more printer conveyance operations with one or more known media handling defects associated with the one or more printer conveyance operations stored in a database;
where the comparison results in a match between the detected media handling defect on the sheet subjected to the one or more printer conveyance operations and the one or more known media handling defects associated with the one or more printer conveyance operations stored in the database; and,
displaying a rectifying action,
wherein, the step of determining that the detected media handling defect matches one or more known media handling defects in the database comprises comparing detected media handling defect signatures to known media handling defect signatures associated with one or more printer conveyance devices, and
wherein, the step of comparing the detected media handling defect signatures to the known media handling defect signatures comprises comparing the detected media handling defect signatures to elements of one or more printer conveyance device component maps.
