Abstract
An image forming apparatus includes an image forming device and circuitry. The image forming device is configured to form an image on a medium. The circuitry is configured to detect a position of the image forming device relative to the medium. The circuitry is further configured to control the image forming device based on the position of the image forming device detected and image data. The circuitry is further configured to control a system state of the image forming device based on the position of the image forming device associated with movement of the image forming device relative to the medium.
Claims19
An image forming apparatus comprising:
- an ink jet recording head configured to form an image on a medium;
- and circuitry configured to:
- determine whether a position of the ink jet recording head is inside an image area or outside the image area, said image area is defined by an origin (0, 0), a maximum value Xanax of the X-coordinate of coordinates of image data of the image, and a maximum value Ymax of the Y-coordinate of the coordinates of the image data of the image;
- measure a first period of time during which the position of the inkjet recording head is outside the image area:
- detect a position of the inkjet recording head relative to the medium, said position including a distance between the medium and the inkjet recording head in a thickness direction of the medium;
- measure a second period of time during which the distance is equal or more than a predetermined threshold value:
- control the ink jet recording head based on the position of the inkjet recording head detected and image data;
- and
- control a system state of the ink jet recording head based on the position of the ink jet recording head associated with movement of the ink jet recording head relative to the medium or a determination result as to whether the position of the inkjet recording head is inside the image area or outside the image area.
A state control method comprising:
- determining whether a position of the ink jet recording head is inside an image area or outside the image area, said image area is defined by an origin (0, 0), a maximum value Xmax of the X-coordinate of coordinates of image data of the image, and a maximum value Ymax of the Y-coordinate of the coordinates of the image data of the image;
- measuring a first period of time during which the position of the ink jet recording head is outside the image area:
- detecting a position of an inkjet recording head relative to a medium on which the ink jet recording head forms an image, said position including a distance between the medium and the ink jet recording head in a thickness direction of the medium;
- measure a second period of time during which the distance is equal or more than a predetermined threshold value;
- controlling the ink jet recording head based on the position of the ink jet recording head detected and image data;
- and
- controlling a system state of the inkjet recording head based on the position of the ink jet recording head associated with movement of the ink jet recording head relative to the medium or a determination result as to whether the position of the ink jet recording head is inside the image area or outside the image area.
A non-transitory, computer-readable storage medium storing computer-readable program code that causes a computer to perform a state control method, the state control method comprising:
- determining whether a position of an inkjet recording head is inside an image area or outside the image area, said image area is defined by the origin (0,0), a maximum value Xmax of the X-coordinate of coordinates of image data of the image, and a maximum value Ymax of the Y-coordinate of the coordinates of the image data of the image;
- measuring a first period of time during which the position of the ink jet recording head is outside the image area:
- detecting a position of an inkjet recording head relative to a medium on which the ink jet recording head forms an image, said position including a distance between the medium and the ink jet recording head in a thickness direction of the medium;
- measure a second period of time during which the distance is equal or more than a predetermined threshold value;
- controlling the inkjet recording head based on the position of the ink jet recording head detected and image data;
- and
- controlling a system state of the inkjet recording head based on the position of the ink jet recording head associated with movement of the ink jet recording head relative to the medium or a determination result as to whether the position of the ink jet recording head is inside the image area or outside the image area.
