Abstract
A data communication apparatus regularly obtains counter information from a plurality of image forming apparatuses. Then, the data communication apparatus moves and writes the counter information that is in a first memory and obtained at a previous time to a second memory. Thereafter, the counter information obtained this time is written to the first memory. At the same time, the data communication apparatus compares the counter information obtained this time with the counter information obtained the previous time. When there is a contradiction between both sets of counter information, the counter information is determined to be a counter abnormality and transmitted to a central management apparatus.
