Embodiment Construction

[0031] Generally speaking, the image quality of MFPs can be divided into three categories: vertical defects, horizontal defects and point defects. From the printed image, vertical defects and horizontal defects are vertical or horizontal white lines or dark lines, and point defects are spots with a diameter of about 3 mm. In the present invention, considering that various defects have different degrees of severity, various defects (image quality) are divided into four levels, that is, level 0 is a normal image without defects, level 1 is a slight defect, level 2 Moderate flaws, level 3 serious flaws.

[0032] However, the above four levels do not limit the technical scope of the present invention, and other embodiments of the present invention may adopt other numbers of levels.

[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0034] The basic strategy for predicting image quality in the prese...
