ABSTRACT:
A recording apparatus for performing recording on a recording medium with an ink jet recording head capable of ink jetting is described. The recording head is closed by capping after turning off the power source or during waiting or when no data is provided from a host unit for a predetermined period of time. To ensure reliable capping, the position of the carriage carrying the head is recognized. According to the invention, in a case when jumping of teeth occurs in a carriage motor drive system gear due to external disturbance of carriage running, the error that occurs in the carriage position recognition is held within one step so that there is no adverse effect on the capping executed during non-recording time such as when recording is ended or when absorbing recovering is executed.
