PURPOSE:To eliminate defective fixing by providing a printer wherein calculation is performed at a controller by using printing quantity in paper, arm position information, rotation information of a feed roller motor, and paper information and a target rotation quantity is supplied to the feed roller motor so as to rotate it. CONSTITUTION:A rotation information of a feed roller motor 18 which discharges papers passed through printing sections 1, 2, 3 via a fixing section 6 is corrected by an information to which a rotation quantity of a paper feed motor 16 is added, so that an information on a paper driving quantity of which influences of change and deformation and slipping of a roller diameter of the feed roller motor 18 are corrected is obtained. A rotation information of an FRM sensor 23 is compared with a rotation information of a PFM sensor 22 so as to decide a desired value of a next rotation quantity in the feed roller motor 18 in such a manner that an angle information of an arm position sensor 20 representing a slack of the paper becomes a predetermined value. In accordance with this desired value, the feed roller motor 18 is rotated. At this time, the angle information of the arm position sensor 20 representing the tension of the paper decides a predetermined angle in accordance with the paper information. Thus, the printing at the printing section can be synchronized with the fixing at the fixing section. |
