Fixation device with abnormal temperature judging mechanism and laser printer using such fixation device
A fixation device performing a fixation process on a medium in conjunction with a pressure roller includes: a fuser heating to a predetermined temperature to perform the fixation process; a temperature sensor senses a temperature of the fuser as time elapses; a controller electrically connected to the fuser and the temperature sensor; and a database connected to the controller and storing heating time data; wherein the controller obtains a heating time period, during which a temperature of the fuser rises from a non-environment temperature to the predetermined temperature, through the temperature sensor, and judges whether the heating time period falls within a qualified range specified by the heating time data. If the heating time period does not fall within the qualified range, then the controller provides an abnormal message, so that the problem of the fixation device can be solved.
