Abstract
The type of printing medium on which an image will be formed is discriminated based upon the image of the medium surface read by an image reading unit for reading the surface as an image. If the discriminated medium type is other than a prescribed printing medium, the image is formed without changing an image formation parameter. When the type of printing medium and the state of the surface are discriminated, image formation can be performed in the most stable image forming mode if an abnormality occurs.
Claims20
An image forming method, for an apparatus which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the method comprising:
- a discriminating step of discriminating the type of printing medium based upon the surface image of the printing medium that has been read by the image reading means;
- and
- an image forming step of forming an image, without changing the image forming parameter, if it has been discriminated at said discriminating step that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming step forms an image upon setting a default for the image forming parameter in a case where communication with the image reading means is impossible.
An image forming method, for an apparatus which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the method comprising:
- a discriminating step of discriminating the type of printing medium based upon the surface image of the printing medium that has been read by the image reading means;
- and
- an image forming step of forming an image, without changing the image forming parameter, if it has been discriminated at said discriminating step that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming step forms an image upon setting a default for the image forming parameter in a case where a reading sensor in the image reading means has malfunctioned.
An image forming method, for an apparatus which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the method comprising:
- a discriminating step of discriminating the type of printing medium based upon the surface image of the printing medium that has been read by the image reading means;
- and
- an image forming step of forming an image, without changing the image forming parameter, if it has been discriminated at said discriminating step that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming step forms an image upon adding on a counterfeit preventing signal without changing the image forming parameter in a case where it cannot be determined whether the type of printing medium is a translucent medium or a reflective medium.
An image forming apparatus, which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the apparatus comprising:
- discriminating means for discriminating the type of printing medium based upon the surface image of the printing medium that has been read by said image reading means;
- and
- image forming means for forming an image, without changing the image forming parameter, if it has been discriminated by said discriminating means that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming means forms an image upon setting a default for the image forming parameter in a case where communication with said image reading means is impossible.
An image forming apparatus, which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the apparatus comprising:
- discriminating means for discriminating the type of printing medium based upon the surface image of the printing medium that has been read by said image reading means;
- and
- image forming means for forming an image, without changing the image forming parameter, if it has been discriminated by said discriminating means that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming means forms an image upon setting a default for the image forming parameter in a case where a reading sensor in said image reading means has malfunctioned.
An image forming apparatus, which has image reading means for reading the surface of a printing medium on which an image will be formed, for setting an image forming parameter based upon the surface image that has been read by the image reading means, and forming an image, the apparatus comprising:
- discriminating means for discriminating the type of printing medium based upon the surface image of the printing medium that has been read by said image reading means;
- and
- image forming means for forming an image, without changing the image forming parameter, if it has been discriminated by said discriminating means that the printing medium is of a type other than a prescribed printing medium,
- wherein said image forming means forms an image upon adding on a counterfeit preventing signal without changing the image forming parameter in a case where it cannot be determined whether the type of printing medium is a translucent medium or a reflective medium.
