Patent ID: 8366333

Claim:
A printing apparatus which conveys a printing medium to a print start position, and causes a printhead to print on the printing medium at the print start position, comprising: a first roller which feeds the printing medium stacked at a stacking position of the printing medium; a second roller which further conveys the printing medium fed by said first roller to the print start position; a driving source which supplies a driving force to said first roller; detection means for detecting a rotational speed of said first roller; generation means for generating a control signal which determines the driving force of said driving source based on the rotational speed detected by said detection means; driving means for driving said driving source by receiving the control signal; first monitor means for monitoring that a value of the control signal becomes larger by a predetermined value compared to the value of the control signal obtained at a predetermined timing, wherein the predetermined timing is a timing before the printing medium fed by said first roller reaches said second roller; and control means for controlling to stop driving said driving source on the basis of a monitor result of said first monitor means.
