Abstract
Printing can continue while replacing ink cartridges. The printerdetects and reports an ink supply disabled state in which ink cannot be supplied from ink cartridgestoIf a cover-open state, in which the coverthat opens and closes the cartridge holderis open, is detected and the ink supply disabled state is also detected while printing is in progress, printing is permitted to continue using ink in buffer tanks (pressure control chambersto) while displaying a warning instead of going to an error state. Interruptions to printing due to a cover-open error while replacing ink cartridgestocan therefore be avoided.
