  • CONTROL DEVICE, IMAGE FORMING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONTROL PROGRAM
    Publication number: 20230095544
    Abstract: A control device includes a first control substrate and a second control substrate each of which includes a processor, a first communication interface, and a second communication interface, the first control substrate and the second control substrate being connected to each other via the first communication interfaces, in which the processor of the first control substrate or the processor of the second control substrate is configured to perform data communication via the second communication interfaces in a case where connection via the second communication interfaces is detected after an error of the data communication performed by the first communication interfaces is detected.

  • CONTROL DEVICE, CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
    Publication number: 20230081383
    Abstract: A control device includes a first control substrate including a processor and a communication interface; and a second control substrate including a processor and a communication interface. The first control substrate and the second control substrate are connected through the communication interfaces. When occurrence of an error in data communication through the communication interfaces is detected, at least one of the processor of the first control substrate and the processor of the second control substrate performs the data communication using unused signal lines among signal lines provided in the communication interfaces.
