The IBM 6640 ink jet printer employs a fog collector device such as the carrier shield 11 illustrated in Fig. 1, the carrier shield being mounted on a moving carriage or carrier 12 (U.S. Patent 4,024,548). The carrier shield includes a small diameter opening 13 through which the printing drops 14 pass for impingement upon the print receiving medium or paper 15. Field experience with these systems has shown that the opening 13 becomes obstructed by paper fibers or dust 16, adhering to the wet or rough surface 17 of the carrier shield 12. A build up of the paper fibers or dust 16 over a period of time may obstruct the opening 13, causing print failure. Disclosed is an automatic means of removing any paper or fiber dust 16 by inhibiting obstruction of the opening 13.
