IMAGE FORMING APPARATUS, JOB PROCESSING CONTROL METHOD AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM STORING JOB PROCESSING CONTROL PROGRAM

摘要

An image forming apparatus includes a print engine, a first CPU that controls operation of the image forming apparatus except for the print engine, a second CPU that controls operation of the print engine, and a shared memory. On executing processing of a print job, the first CPU performs a job management including managing job management information and storing the job management information in a data area of the shared memory, and the first CPU outputs image data to be printed, stored in the data area, to the print engine. The second CPU monitors an operation state of the first CPU and, on determining that the abnormality is occurring in the first CPU, maintains the processing of the print job by outputting the image data to be printed to the print engine as proxy for the first CPU and performing the job management as proxy for the first CPU.
