Abstract
An example image forming apparatus that detects an error of an image formed on a printing medium, the apparatus includes a print engine, an inline scanner located at an output end of the print engine, and a processor. The processor is to obtain information of print data of a received print job, form an image on a printing medium based on the print data by using the print engine, obtain information of a print image of the printing medium on which the image is formed by using the inline scanner, detect whether normal output is performed by comparing the information of the print data with the information of the print image, and, in a case where the normal output is not detected, detect an output error and perform re-output.
Claims13
An image forming apparatus comprising:
- a print engine;
- an inline scanner located at an output end of the print engine;
- and
- a processor,
- wherein the processor is to:
- obtain information of print data of a received print job including size information of an original image and set printing medium information,
- form an image on a printing medium based on the print data by using the print engine,
- obtain information of a print image of the printing medium on which the image is formed by using the inline scanner, wherein the information of the print image comprises size information of the print image,
- detect whether a normal output is performed by comparing the size information of the original image with the size information of the print image, and
- detect an output error in response to the size information of the original image and the size information of the print image not matching and perform re-output.
An error detection method of an image formed on a printing medium, the method comprising:
- obtaining information of print data of a received print job and forming an image on a printing medium based on the print data, wherein the information of the print data comprises size information of an original image and set printing medium information;
- obtaining information of a print image of the printing medium on which the image is formed by using an inline scanner, wherein the information of the print image comprises size information of the print image;
- detecting whether a normal output is performed by comparing the size information of the original image with the size information of the print image, and
- detecting an output error in response to the size information of the original image and the size information of the print image not matching and performing re-output.
A non-transitory computer-readable recording medium on which a program for performing an error detection method of an image formed on a printing medium is recorded, the recording medium comprising:
- instructions to obtain information of print data of a received print job and forming an image on a printing medium based on the print data, wherein the information of the print data comprises size information of an original image and set printing medium information;
- instructions to obtain information of a print image of the printing medium on which the image is formed by using an inline scanner, wherein the information of the print image comprises size information of the print image;
- instructions to detect whether a normal output is performed by comparing the size information of the original image with the size information of the print image;
- and
- instructions to detect an output error in response to the size information of the original image and the size information of the print image not matching and perform re-output.
