The MK-U Series Universal Inkjet Printer is the world’s first self-cleaning printer, featuring an auto-shower cleaning function. Conventional continuous inkjet (CIJ) printers required daily head cleaning conducted by operators. It's typically unclear to them which parts should be cleaned and how thoroughly. The degree of cleanliness depends on the operator, which is one of the main causes of nozzle clogging. The auto-shower cleaning function cleans critical parts inside the head precisely and automatically with just the press of a button. It can also prevent variations in the amount and effort of cleaning caused by different operators. Furthermore, the minimum amount of solvent are used, which can significantly reduce running costs.
