A control device includes an apparatus controller that is connected to at least one apparatus and includes a first memory which stores data for controlling the driving of the apparatus and data indicating a state of the apparatus and a reading and transmitting unit which reads each data item stored in the first memory and transmits the read data, a main controller that includes a central processing unit, a second memory, and a writing unit which writes the data transmitted from the apparatus controller to the second memory, and a full-duplex serial bus that connects the main controller and the apparatus controller. The reading and transmitting unit and the writing unit operate such that each data item stored in the first memory is read, transmitted, and stored in the second memory in a cycle equal to or less than a count cycle of a system timer.

There is provided a data processing device that includes an obtaining unit that obtains a first image data set, a second image data set generated by reading an image formed using the first image data set, and a property data set indicating the properties of a recording medium on which the image is to be reproduced. The data processing device also includes a specifying unit that determines a threshold for a density difference between the first image data set and the second image data set, wherein the threshold depends on the property data set. The specifying unit also determines an error area where the density difference between images expressed by the first and second image data sets is equal to or greater than the threshold.

Data processing device, image forming device, system, and a computer-readable recording medium for determining whether or not image is properly formed on recording medium

The invention provides an information processing apparatus including: a plurality of abnormality detection sections provided in each of a plurality of detection target portions, that detect an abnormality caused by high temperature at a predetermined first frequency; an indication detecting section that detects an indication that the abnormality will occur; and a controller that controls to set the detection frequency of the plurality of abnormality detection sections to a second frequency which is higher than the first frequency, when the number of times that the indication is detected within a predetermined period is more than a predetermined number of times.

Abnormality detection frequency set when it is indicated that abnormality will occur
