Abstract
Disclosed is a heat roller control device comprising a high temperature malfunction detection unit configured to receive a temperature value detected by a heat roller temperature sensor; an electrical power control unit configured to cut off, when receiving a high temperature malfunction detection signal, power feeding to a heat roller from an electrical power unit; an analog-to-digital converter configured to periodically convert plural of the temperature values from the heat roller temperature sensor to plural digital temperature values; a temperature value storage unit configured to receive and store the plural digital temperature values from the analog-to-digital converter; a temperature value processing unit configured to read and process the plural digital temperature values stored in the temperature value storage unit; and a high temperature malfunction determination unit configured to receive the processed data, and then based on the processed data, determine whether high temperature malfunction occurs.
