Abstract
Abstract A monitor system comprises a detector unit for detecting the state of an image forming device, and a transmitter unit for transmitting the status data representing the state to a monitor device upon a state change being detected by the detector unit. If the transmitter unit fails to transmit the status data, it stores the status data and transmits the status data stored upon the new state change being detected by the detector unit. This allows for the secure transmission of the status data of the image forming device which has not been transmitted to the monitor device due to a temporary malfunction of the line.
