Image forming apparatus and control method for confirming a paper rolling state of a fusing device

摘要

An image forming apparatus and a control method thereof in which occurrence or removal of a paper rolling state in a fusing device is judged based on temperature of the fusing device. The apparatus includes a temperature sensor to sense temperature of the fusing device, a memory to store information about occurrence or removal of the paper rolling state, and a controller to judge occurrence or removal of the paper rolling state. The controller detects an initial temperature of the fusing device when the apparatus is turned off and then on in a state in which the information about occurrence of the paper rolling state is stored in the memory, heats the fusing device by applying power thereto for a predetermined time based on the initial temperature, and judges occurrence or removal of the paper rolling state based on temperature of the fusing device detected after power application.

主权项

1. An image forming apparatus comprising:
a fusing device; a temperature sensor to sense a temperature of the fusing device; a memory in which information about occurrence and removal of a paper rolling state in the fusing device is stored; and a controller, which detects an initial temperature of the fusing device when the image forming apparatus is turned on in a state in which information about occurrence of the paper rolling state is stored in the memory, which heats the fusing device by applying power to the fusing device for a predetermined time, and which judges whether or not the paper rolling state has been removed based on the temperature of the fusing device.
