Abstract
A method of performing error notification and error recovery functions in an image forming apparatus includes detecting by one or more sub-processors an error of a main processor for controlling the sub-processors; controlling an interface function of the image forming apparatus if the error is detected; outputting information about the detected error; and recovering the detected error by controlling an operation of the main processor.
Claims20
A method of performing error notification and error recovery functions in an image forming apparatus, the method comprising:
- detecting an error of a main processor for controlling a plurality of sub-processors, the sub-processors each controlling units included in the image forming apparatus, wherein the error is detected by at least one sub-processor among the plurality of sub-processors;
- controlling a function of receiving data about a printing operation from outside the image forming apparatus when the error is detected;
- outputting information about the detected error;
- and
- recovering the detected error by controlling an operation of the main processor.
An image forming apparatus having error notification and error recovery functions, the image forming apparatus comprising:
- a plurality of sub-processors each controlling units included in the image forming apparatus;
- and
- a main processor controlling the plurality of sub-processors,
- wherein at least one of the plurality of sub-processors comprises:
- an error detector detecting an error generated in the main processor;
- an interface controller controlling a function of receiving data about a printing operation from outside the image forming apparatus when the error is detected;
- an error notification unit outputting information about the detected error;
- and
- an error recovery unit recovering the detected error by controlling an operation of the main processor.
