Abstract
A method of moving a cap apart from a printhead within a short period of time without damaging a printing apparatus when the cap sticks to the printhead. A cap moving unit is driven to try to move the cap apart from the printhead. When a detection unit for detecting that the cap has moved apart from the printhead detects that the cap has not moved apart from the printhead, it is controlled to slightly reciprocate the carriage while driving the cap moving unit. When the detection unit detects that the cap has moved apart from the printhead under this control, the slight reciprocation of the carriage is forcibly stopped.
