Abstract
An ink jet printer having an ink jet head and defining a structure having a device including a structure defining a plurality of orifices for ejecting ink droplets includes defining an ink cleaning cavity spaced from the printing position for receiving cleaning fluid; a roller disposed in the cleaning cavity and partially submerged in the cleaning fluid and spaced from the structure is rotated so that the fluid coats the roller and is carried by surface tension around the roller; and the structure is brought into proximity with the cleaning roller so that the orifices are cleaned by the cleaning fluid carried on the roller and delivered through the cleaning cavity to the structure.
