Abstract

There is provided an apparatus and a method of detecting a home position of a carriage, achieving a less manufacturing cost. The apparatus includes a position detecting part to detect a position of a carriage driven by a motor; a first drive control part to control the motor so that the carriage is transferred toward a frame of a printer until being stopped, the frame being provided at a home position range side; a second drive control part to control the motor so that the carriage is transferred toward another frame of the printer until being stopped, the other frame being provided opposite to the frame provided at the home position range side; a third drive control part to control the motor so that the carriage is transferred to a predetermined position close to the home position range; and a selection control part to select one of the first, the second, and the third drive control parts and control the selected drive control part, thus detecting a home position of the carriage based on a result of the selective control and the output of the position detecting part.
