Benefits of technology

[0008] The object of an aspect of the present invention is to provide an image forming apparatus and a data overwriting method, which can prevent mismatching of data between respective pro

Problems solved by technology

In this overwrite method, however, if data overwrite fails during the data overwrite operation, or if power is disrupted during the data overwrite, there would be such cases that data is lost and normal operation cannot be started even if the apparatus is rebooted or power is turned on again.
In addition, when specific data is overwritten, mismatching would occur in data between respective processing sections and there would be s

Embodiment Construction

[0016] An embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017]FIG. 1 schematically shows the structure of an image forming apparatus according to the present invention. An image forming apparatus 20 comprises a system processing section 2, a scan processing section 4 and a print processing section 6. A controller 1 is connected to the image forming apparatus 20 via an interface (I / F) 13. In addition, an option processing section 9 is connected to the image forming apparatus 20.

[0018] The controller 1 is connected to a Web site 12 that provides data via the Internet 14. As will be described later in detail, the controller 1 acquires data from the Web site 12 that provides data.

[0019] The system processing section 2 includes a storage device 3 comprising a non-volatile memory. An external storage device 8 is connected to the system processing section 2. The system processing section 2 controls the entirety of the apparatus. The

Abstract

At the time of start of a reboot operation or a boot operation of an image forming apparatus, a system processing section confirms whether a configuration of an option processing section has changed, and whether data in storage devices in processing sections has changed. If the image forming apparatus fails to normally operate due to a combination of changed data, the system processing section overwrites data in the storage devices in the respective processing sections, with use of data stored in an external storage device, thereby realizing a latest, optimal combination of data.
