Inspection device comparing a scan image to a reference image, image forming apparatus, and program for inspection device

A non-transitory recording medium storing a computer readable program causing a computer of an inspection device to perform:

• generating a reference image used for inspection of an image formed on a recording medium and performing the inspection, the program causing the computer to perform the steps of:
• in a case where the reference image being newly generated is set on the inspection,
• acquiring a plurality of first read images generated by reading each first recording medium of a plurality of first recording media, one image in an inspection target print job being formed on each of the first recording media;
• performing inspection on a second read image generated by reading a second recording medium on which the one image is formed, by using a read image, as the reference image, used for inspection among the plurality of first read images acquired;
• and
• storing the reference image in a storage,
• wherein in a case where the reference image not being newly generated is set on the inspection, the program uses the reference image stored in the storage without newly acquiring the first read image.

An inspection system generating a reference image used for inspection of an image formed on a recording medium and performing the inspection, the inspection system comprising:

• an image former that forms an image on the recording medium;
• an image reader that reads a recording medium on which one image in an inspection target print job is formed by the image former, and generates a read image;
• and
• a hardware processor that, in a case where the reference image being newly generated is set on the inspection, acquires a plurality of first read images generated by the image reader reading each first recording medium of a plurality of first recording media, the one image being formed on each of the first recording media, and performs inspection on a second read image generated by the image reader reading a second recording medium on which the one image is formed, by using a read image, as the reference image, used for inspection among the plurality of first read images acquired,
• wherein the hardware processor stores the reference image in a storage, and
• wherein in a case where the reference image not being newly generated is set on the inspection, the inspection system uses the reference image stored in the storage without newly acquiring the first read image.

An inspection method in an inspection system generating a reference image used for inspection of an image formed on a recording medium and performing the inspection, the inspection method comprising the steps of:

• forming an image on a recording medium;
• generating a read image by reading a recording medium on which one image in an inspection target print job is formed in the forming an image;
• in a case where the reference image being newly generated is set on the inspection, acquiring a plurality of first read images generated by reading each first recording medium of a plurality of first recording media, the one image being formed on each of the first recording media, and performs inspection on a second read image generated by reading a second recording medium on which the one image is formed, by using a read image, as the reference image, used for inspection among the plurality of first read images acquired;
• and
• storing the reference image in a storage,
• wherein in a case where the reference image not being newly generated is set on the inspection, the inspection method uses the reference image stored in the storage without newly acquiring the first read image.
