Method of automatically inserting printing paper in an automatic paper feeder
 A method of automatically inserting a printing paper in a hopper of an automatic paper feeder or a manual insertion printing paper inserted from a manual paper input slot. Upon receiving an instruction to insert a printing paper by a printer, a platen is first rotated. Thereupon, provided the presence of the printing paper is detected by a sensor even with the platen being rotated by a prescribed amount, a paper feed motor of the automatic paper feeder is rotated for obtaining a printing paper from the hopper. While, provided the presence of a printing paper is detected before the platen is rotated by the prescribed amount, the paper feed motor is not rotated, it being assumed that the manual insertion of a printing paper has been already performed. After detected the presence of the printing paper, the platen is rotated by a prescribed amount to cause the printing paper to be moved to a position where a first line of the printing paper faces the face of the printing head.
