Title:
画像形成装置および画像形成装置の制御方法
Document Type and Number:
Japanese Patent JP6911615
Kind Code:
B2
Abstract:
To provide an image formation apparatus which can highly accurately perform the quality check of an output object even when a variation occurs in processing positions of processed sheets.SOLUTION: An image formation apparatus includes: a first reading unit 20 which is provided on the upstream side of an image formation unit 30 and reads processing position information of a processed sheet 70 before image formation; and a second reading unit 40 which is provided on the downstream side of the image formation unit 30 and reads an image of an output object formed with the image and output by the image formation unit 30. The image formation apparatus acquires the image of the output object read by the second reading unit 40 as a reference image, calculates a deviation amount between a processing position based on the processing position information read by the first reading unit 20 and a processing position based on the processing position information read by the first reading unit 20 when acquiring the reference image, compares the image of the output object read by the second reading unit 40 with the reference image after adjusting the relative positions between the output object and the reference image by the deviation amount, and determines the quality of the output object based on the comparison result.SELECTED DRAWING: Figure 1
