Abstract
A fail-safe capability is realized that not only forestalls the execution by the user of the head replacement operation in an erroneous sequence while the printing apparatus is in operation but also prevents the splashing of ink even if the user attempts to inadvertently replace the print head. For this purpose, the ink supply and the opening and closing of the print head replacement cover are performed by a predetermined rotation of one drive source.
