Patent ID: 7762733

Claim:
A printing apparatus which feeds a stacked printing medium, conveys the printing medium to a print start position, and causes a printhead to print on the printing medium, comprising: a first roller which feeds the printing medium from a stacking position of the printing medium into the apparatus; a second roller which further conveys the printing medium fed by said first roller to the print start position; a DC motor which supplies a driving force to said first roller and said second roller; an encoder which detects a rotation amount and rotational speed of said first roller; a sensor, provided at a predetermined position along a feed-conveyance path of the printing medium, for detecting a tip of the printing medium; generation means for generating a PWM signal by feeding back the rotation amount and rotational speed detected by said encoder; driving means for driving said DC motor by receiving the PWM signal; first monitor means for monitoring that a value of the PWM signal becomes larger than a predetermined value with respect to the value of the PWM signal obtained at a timing when said sensor detects the tip of the fed printing medium; and control means for controlling to stop driving said DC motor on the basis of a monitor result of said first monitor means.
