Abstract
A host apparatus, an image forming apparatus, and a diagnosis method for the image forming apparatus, the diagnosis method including: storing a printing image generated from print data according to a printing command; and generating a diagnosis image for the printing image based on the stored printing image and a defect image corresponding to a predetermined defect of the image forming apparatus.
Claims31
A diagnosis method to determine defects of an image forming apparatus, the diagnosis method comprising:
- transmitting a printing image generated from print data according to a printing command to the image forming apparatus for printing;
- copying and storing the transmitted printing image;
- generating a diagnosis image for the stored printing image by synthesizing the stored printing image and at least one of a plurality of defect images of the image forming apparatus,
- wherein the plurality of defect images are previously stored corresponding to a plurality of defects, respectively, which are occurred in the image forming apparatus.
A host apparatus to diagnose a defect in an image forming apparatus, the host apparatus comprising:
- an image processing part to generate a printing image from print data according to a printing command;
- a communication part to transmit the generated printing image to the image forming apparatus for printing;
- a storage part to store a previously stored defect image of the image forming apparatus;
- a controller to copy and store the transmitted printing image in the storage part and to control the image processing part to generate a diagnosis image for the printing image by synthesizing the stored printing image and at least one of a plurality of defect images,
- wherein the plurality of defect images are previously stored corresponding to a plurality of defects, respectively, which are occurred in the image forming apparatus.
An image forming apparatus to diagnose a defect therein, the image forming apparatus comprising:
- an image processing part to process a printing image from print data;
- a controller to control the image processing part to copy and store the processed printing image in a storage part and to generate a diagnosis image for the stored printing image based on the printing image and at least one of a plurality of defect images of the image forming apparatus,
- wherein the plurality of defect images are previously stored corresponding to a plurality of defects, respectively, which are occurred in the image forming apparatus.
