Abstract
A detection system includes an image reader, circuitry, a display, and a cleaner. The image reader has a reading face to read, in a scanning direction, an image on a sheet fed on the reading face. The circuitry is to detect a foreign matter adhered to the reading face, and calculate a distance, in the scanning direction, between an adhesion point where the foreign matter is adhered to the reading face and a reference point on the reading face. The display displays the distance calculated. The cleaner has a scale in the scanning direction. The scale corresponds to the distance displayed on the display, and is movable in the scanning direction to remove the foreign matter adhered to the reading face.
Claims8
A detection system comprising:
- an image reader having a reading face to read, in a scanning direction, an image on a sheet fed on the reading face;
- circuitry configured to:
- detect a foreign matter adhered to the reading face;
- and
- calculate a distance, in the scanning direction, between:
- an adhesion point where the foreign matter is adhered to the reading face;
- and
- a reference point on the reading face;
- a display to display the distance calculated;
- and
- a cleaner:
- having a scale in the scanning direction, the scale corresponding to the distance displayed on the display;
- and
- movable in the scanning direction to remove the foreign matter adhered to the reading face.
A detection method executed in a detection system, the detection method comprising:
- detecting a foreign matter adhered to a reading face of an image reader;
- calculating a distance, in a scanning direction, between:
- an adhesion point where the foreign matter is adhered to the reading face;
- and
- a reference point on the reading face of the image reader;
- displaying the distance calculated;
- and
- removing the foreign matter adhered to the reading face of the image reader by a cleaner having a scale in the scanning direction, the scale corresponding to the distance displayed on the display.
