Abstract
A fixing apparatus includes: a first rotating body that contacts a sheet for printing and heats the sheet; a second rotating body that rotates while pressing the first rotating body; a motor that rotates the first rotating body; and a hardware processor that determines whether an abnormal noise occurs on the basis of a plurality of condition values including a torque value of the motor, wherein the hardware processor performs abnormal noise prevention control that increases the rotation of the first rotating body or weakens pressing applied by the second rotating body to the first rotating body in a case where it is determined that the abnormal noise occurs.
Claims11
A fixing apparatus, comprising:
- a first rotating body that contacts a sheet for printing and heats the sheet;
- a second rotating body that rotates while pressing the first rotating body;
- a motor that rotates the second rotating body;
- and
- a hardware processor that determines whether an abnormal noise occurs on the basis of a plurality of condition values including a torque value of the motor, wherein
- the hardware processor performs abnormal noise prevention control that increases the rotation of the first rotating body or weakens pressing applied by the second rotating body to the first rotating body in a case where it is determined that the abnormal noise occurs.
A method of controlling a fixing apparatus including a first rotating body that contacts a sheet for printing and heats the sheet, a second rotating body that rotates while pressing the first rotating body, and a motor that rotates the second rotating body, the method comprising:
- determining whether an abnormal noise occurs on the basis of a plurality of condition values including a torque value of the motor;
- and
- performing abnormal noise prevention control that increases the rotation of the first rotating body or weakens pressing applied by the second rotating body to the first rotating body in a case where it is determined that the abnormal noise occurs.
A non-transitory recording medium storing a computer readable program used in a computer that controls a fixing apparatus including a first rotating body that contacts a sheet for printing and heats the sheet, a second rotating body that rotates while pressing the first rotating body, and a motor that rotates the second rotating body, the non-transitory recording medium causing the computer to perform:
- determining that determines whether an abnormal noise occurs on the basis of a plurality of condition values including a torque value of the motor;
- and
- preventing an abnormal noise, the preventing increasing the rotation of the first rotating body or weakening pressing applied by the second rotating body to the first rotating body in a case where it is determined by the determining that the abnormal noise occurs.
