US 12,634,401 B2 · Inspection system and method of controlling the same, and storage medium that determine whether a continuous image defect has occurred

Abstract

An inspection system including a printing apparatus, an inspection apparatus, and controllers to cause a reading device to read a printed matter, for which the printing apparatus has printed an image on a recording sheet, to obtain image data, to obtain a shift amount between a preceding first recording sheet and a following second recording sheet in a direction orthogonal to a conveyance direction of a recording sheet used for printing, to detect an image defect in the obtained image data, and to diagnose a failure location of the printing apparatus based on an inspection detection result. The diagnosis determines whether a continuous image defect has occurred based on a position of an image defect in the preceding first recording sheet and a position of an image defect in the following second recording sheet. The obtained shift amount and the failure location are diagnosed based on the determined image defect.

Dependent claims

An inspection system comprising:

a printing apparatus;
an inspection apparatus;
and
one or more controllers including one or more processors and one or more memories, the one or more controllers configured:
to cause a reading device of the inspection apparatus to read a printed matter for which the printing apparatus has printed an image on a recording sheet to obtain image data of the image;
to obtain a shift amount between a preceding first recording sheet and a following second recording sheet in a direction orthogonal to a conveyance direction of a recording sheet used by the printing apparatus for printing;
to cause the inspection apparatus to detect an image defect included in the image data obtained by the reading device performing reading;
and
to diagnose a failure location of the printing apparatus based on a result of detection by the inspection apparatus,
wherein, in the diagnosis, it is determined whether a continuous image defect has occurred based on a position of an image defect included in the preceding first recording sheet and a position of an image defect included in the following second recording sheet and the obtained shift amount, and the failure location is diagnosed based on the determined continuous image defect.
