Abstract
An ink jet printer which has a cover that can be opened to expose the interior of the apparatus to allow the ink tank and print head to be replaced and in which when the cover is detected to be opened, the apparatus is set so that the replacement of the ink tank or print head can be made, when the cover is opened for other purposes not accompanied by the replacement, unnecessary operations such as the replacement enable setting are eliminated. Hence, when the cover is opened during a standby state in which no print data is received and there is no error, the above setting (e.g., moving the print head to the replacement position) is permitted. When the cover is opened during the printing operation or in the presence of a print medium jam error, the apparatus does not permit the setting and waits for the cover to be closed. In this way, the predetermined setting in the event of the opening of the cover is properly controlled according to the mode of the apparatus to improve the operability and the operation efficiency.
