Abstract
An example image forming apparatus includes an image forming apparatus, a processor, and a memory storing instructions executable by the processor. The processor of the image forming apparatus executes the instructions to render a print job, obtain information regarding a pattern for determining print quality from a rendered image of the print job, scan, through the image forming job unit, a document on which the rendered image is printed, and determine the print quality based on a scanned image of the document and the obtained information regarding the pattern.
Claims20
An image forming apparatus comprising:
- an image forming job unit;
- a processor;
- and
- a memory to store instructions executable by the processor and a pattern of a diagnostic item,
- wherein the processor is to execute the instructions to:
- render a print job;
- identify whether a rendered image of the print job includes an object corresponding to the pattern of the diagnostic item;
- based on the rendered image of the print job including the object corresponding to the pattern of the diagnostic item, obtain color information of the object in the rendered image based on a location of the object in the rendered image;
- based on the color information corresponding to the pattern of the diagnostic item, identify that the object includes a pattern for determining print quality;
- scan, through the image forming job unit, a document on which the rendered image is printed;
- and
- determine the print quality based on a scanned image of the document and the pattern for determining the print quality.
A method of determining print quality, the method comprising:
- rendering a print job;
- identifying whether a rendered image of the print job includes an object corresponding to a pattern of a diagnostic item;
- based on the rendered image of the print job including the object corresponding to the pattern of the diagnostic item, obtaining color information of the object in the rendered image based on a location of the object in the rendered image;
- based on the color information corresponding to the pattern of the diagnostic item, identifying that the object includes a pattern for determining print quality;
- scanning a document on which the rendered image is printed;
- and
- determining the print quality based on a scanned image of the document and the pattern for determining the print quality.
A non-transitory computer-readable recording medium storing instructions executable by a processor, the computer-readable recording medium comprising:
- instructions to render a print job;
- instructions to identify whether a rendered image of the print job includes an object corresponding to a pattern of a diagnostic item;
- instructions to, based on the rendered image of the print job including the object corresponding to the pattern of the diagnostic item, obtain color information of the object in the rendered image based on a location of the object in the rendered image;
- instructions to, based on the color information corresponding to the pattern of the diagnostic item, identify that the object includes a pattern for determining print quality;
- instructions to scan a document on which the rendered image is printed;
- and
- instructions to determine the print quality based on a scanned image of the pattern for determining the print quality.
