FIELD: information technology.
SUBSTANCE: invention relates to an image forming device, such as a printer and fax machine or copier, where there is a fixing roller, in which there is a source of heating. Disclosed is a fixing device, comprising: first and second sensors for detection of first and second temperatures; first and second units of calculation for calculation of during start heating source of first and second temperature drops; memory parameter to store at least first and second threshold values of temperature drop; determination unit for producing determination result; unit for generating information for generating, based on a result of determination, information indicating on restart, indicating that image forming device should be restarted, because voltage power supply too low; and unit for transmitting information for transmitting information indicating on restart to a display device.
EFFECT: technical result is creation of an image forming apparatus for informing user about incorrect operation of imaging device, when it cannot start due to low voltage.
