Image forming apparatus that calibrates a folding position
An image forming apparatus includes: a folder configured to fold a medium by forming a fold such that a side of the medium is aligned with a predetermined first position on the medium; and an image forming device configured to form a first image on a region different from a region located within a predetermined range from the first position, on at least a part of the side of the medium before the medium is folded by the folder.
1. An image forming apparatus comprising:
a folder configured to fold a medium by forming a fold such that a side of the medium is aligned with a predetermined first position on the medium;
an image forming device configured to form a first image on a region different from a region located within a predetermined range from the first position, on at least a part of the side of the medium before the medium is folded by the folder; and
a processor programmed to:
control the folder and the image forming device:
acquire an image obtained by reading the medium in a state of being folded by the folder;
measure a distance between the first image and the first position from the acquired image; and
adjust a position where the folder folds the medium according to the measured distance.
2. The image forming apparatus according to claim 1 , wherein the folder is configured to fold the medium such that the fold does not intersect with any position on the side where the first image is formed by the image forming device.
3. The image forming apparatus according to claim 2 , wherein the image forming device is configured to form the first image at each of two or more positions on the side.
4. The image forming apparatus according to claim 3 , wherein
the folder is configured to fold the medium at a position different from the fold such that the fold is aligned with a predetermined second position on the medium, and
the image forming device is configured to form a second image on a region different from a region located within a predetermined range from the second position, on at least a part of a portion that is a mountain side of the fold of the medium before the medium is folded by the folder.
5. The image forming apparatus according to claim 4 , wherein the image forming device is configured to form the second image at each of two or more positions of the fold.
6. The image forming apparatus according to claim 2 , wherein
the folder is configured to fold the medium at a position different from the fold such that the fold is aligned with a predetermined second position on the medium, and
the image forming device is configured to form a second image on a region different from a region located within a predetermined range from the second position, on at least a part of a portion that is a mountain side of the fold of the medium before the medium is folded by the folder.
7. The image forming apparatus according to claim 6 , wherein the image forming device is configured to form the second image at each of two or more positions of the fold.
8. The image forming apparatus according to claim 1 , wherein the image forming device is configured to form the first image at each of two or more positions on the side.
9. The image forming apparatus according to claim 8 , wherein
the folder is configured to fold the medium at a position different from the fold such that the fold is aligned with a predetermined second position on the medium, and
the image forming device is configured to form a second image on a region different from a region located within a predetermined range from the second position, on at least a part of a portion that is a mountain side of the fold of the medium before the medium is folded by the folder.
10. The image forming apparatus according to claim 9 , wherein the image forming device is configured to form the second image at each of two or more positions of the fold.
11. The image forming apparatus according to claim 1 , wherein
the folder is configured to fold the medium at a position different from the fold such that the fold is aligned with a predetermined second position on the medium, and
the image forming device is configured to form a second image on a region different from a region located within a predetermined range from the second position, on at least a part of a portion that is a mountain side of the fold of the medium before the medium is folded by the folder.
12. The image forming apparatus according to claim 11 , wherein the image forming device is configured to form the second image at each of two or more positions of the fold.
13. The image forming apparatus according to claim 1 , wherein
the image forming device comprises a cleaning unit configured to clean a path through which the medium has passed every time the first image is formed on the medium.
14. An image forming apparatus comprising:
an image forming device configured to form a first image on at least one side among two sides at an alignment position on an opposite side to a folding position on a medium;
a folder configured to fold the medium on which the first image is formed by the image forming device such that the same image as the first image formed on the at least one side of the two sides at the alignment position is not on the other side when the medium is folded; and
a processor programmed to:
control the folder and the image forming device:
acquire an image obtained by reading the medium in a state of being folded by the folder;
measure a distance between the first image and the first position from the acquired image; and
adjust a position where the folder folds the medium according to the measured distance.
