Patent ID: 11163513

Abstract:
An image forming apparatus includes a first processor, a second processor, a data transfer portion, a consistency determination portion, an abnormality determination portion, a re-transfer control portion, and an abnormality processing portion. The data transfer portion transfers data via a bus between a storage medium and the second processor. The consistency determination portion determines whether or not there is consistency between data before and after a transfer by the data transfer portion. The abnormality determination portion, upon determination that there is consistency, determines whether or not there is abnormality in the data transfer process. The re-transfer control portion, upon determination that there is no consistency, causes the data transfer portion to re-transfer the data. The abnormality processing portion, upon determination that there is abnormality in the data transfer process, prohibits the re-transfer control portion from re-transferring the data, and executes an abnormality process to handle the abnormality.
