Image forming apparatus and non-transitory computer readable medium
An image forming apparatus includes a memory, and a processor configured to: read a first image of a sheet in a state in which the sheet is held on a sheet holding unit, the sheet being a sheet on which an image has been formed; detect a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image; and, when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, perform a correction process of matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol.
1. An image forming apparatus comprising:
a memory; and
a processor configured to
read a first image of a sheet held on a sheet holding unit, the sheet being a sheet on which an image has been formed,
detect a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image,
when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, perform a correction process comprising matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol, and
when the symbol indicating the orientation of the first image fails to be detected from the first image of the sheet which has been read, notify a user that the sheet is to be turned over.
2. The image forming apparatus according to claim 1 ,
wherein the processor is configured to form a third image on the sheet, the third image being superimposed on the detected symbol to hide the detected symbol.
3. The image forming apparatus according to claim 2 ,
wherein the processor is configured to form the third image on the sheet at a position, on the sheet, of the symbol detected from the first image of the sheet which has been read, the third image being of a preset size.
4. The image forming apparatus according to claim 2 ,
wherein a color of the third image is in color series identical to a background color of the sheet.
5. The image forming apparatus according to claim 1 ,
wherein the correction process comprises, when the orientation of the first image indicated by the detected symbol is different from the orientation of the second image that is to be formed on the sheet, notifying a user that the orientation of the sheet is to be reversed.
6. The image forming apparatus according to claim 1 ,
wherein the correction process comprises, when the orientation of the first image indicated by the detected symbol is different from the orientation of the second image that is to be formed on the sheet, rotating the orientation of the second image that is to be formed on the sheet.
7. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
reading a first image of a sheet held on a sheet holding unit, the sheet being a sheet on which an image has been formed;
detecting a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image;
when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, performing a correction process comprising matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol; and
when the symbol indicating the orientation of the first image fails to be detected from the first image of the sheet which has been read, notifying a user that the sheet is to be turned over.
8. An image forming apparatus comprising:
means for storing data;
means for reading a first image of a sheet held on a sheet holding unit, the sheet being a sheet on which an image has been formed;
means for detecting a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image; and,
means for, when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, performing a correction process comprising matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol; and
means for, when the symbol indicating the orientation of the first image fails to be detected from the first image of the sheet which has been read, notifying a user that the sheet is to be turned over.
