Abstract
An image inspection system includes an inspection level setting support mode in which a printed material which is a sheet on which a content has already been printed, set in a sheet feeder and fed from the sheet feeder is conveyed to the conveyance route, and the threshold value for the inspection level is set by detecting an image defect based on a first read image obtained by reading the printed material with an image reader in a state where printing operation of an image former is turned off.
Claims14
An image inspection system comprising:
- a sheet feeder;
- an image former that forms an image on a sheet fed and conveyed from the sheet feeder;
- and
- an image reader that is arranged downstream of the image former on a conveyance route along which the sheet is conveyed and reads the image on the sheet, wherein
- the image inspection system detects an image defect using a threshold value for an inspection level set using a read image generated by reading with the image reader, and
- the image inspection system includes an inspection level setting support mode in which a printed material which is a sheet on which a content has already been printed, set in the sheet feeder and fed from the sheet feeder is conveyed to the conveyance route, and the threshold value for the inspection level is set by detecting an image defect based on a first read image obtained by reading the printed material with the image reader in a state where printing operation of the image former is turned off.
An image inspection apparatus that detects an image defect using a threshold value of an inspection level set using a read image generated by reading with an image reader that is arranged downstream of an image former on a conveyance route along which a sheet is conveyed and reads an image on the sheet, comprising an inspection level setting support mode in which a printed material on which user content including an image defect, not a test chart, has been printed, set in a sheet feeder is fed and conveyed from the sheet feeder, and the threshold value of the inspection level is set by detecting an image defect based on a first read image obtained by reading the printed material with the image reader in a state where printing operation of the image former is turned off.
An inspection level setting support method for image inspection that is executed in an image inspection system comprising a sheet feeder, an image former that forms an image on a sheet fed and conveyed from the sheet feeder, and an image reader that is arranged downstream of the image former on a conveyance route along which the sheet is conveyed and reads the image on the sheet, that detects an image defect using a threshold value of an inspection level set using a read image generated by reading with the image reader, the inspection level setting support method comprising:
- a step of feeding and conveying, from the sheet feeder, a printed material on which user content including an image defect, not a test chart, has been printed, set in the sheet feeder;
- a step of printing blank page data including substantially no image as a document image of a print job on the printed material in a state where printing operation of the image former is activated in a normal printing state;
- and
- a step of setting the threshold value of the inspection level by detecting an image defect based on a read image obtained by reading the printed material with the image reader.
