ABSTRACT OF THE DISCLOSURE A paper feed system in a printer includes a platen for supporting a recording paper sheet, a paper feed drive motor, and a transmission gear mechanism for transferring the rotation of the paper feed drive motor to the platen so as to conduct an automatic paper feed operation. The paper feed system further allows a manual paper feed operation wherein the platen is manually rotated. A detection system is provided which detects the manual paper feed operation. If the manual paper feed operation has been conducted before the automatic paper feed operation, a compensating paper drive is first con- ducted when an automatic paper feed instruction is developed. In the compensating paper drive, the platen is first driven to rotate in a reverse direction by a predetermined amount and then to rotate in a forward direction by the same amount, thereby compensating for the displacement of the paper sheet location caused by the backlash of the transmission gear mechanism during the manual paper feed operation. * * * * * * * * * *
