<p>A printing apparatus (10) including a print head (24) which is used in conjunction with a floating platen (28) is disclosed. The print head (24) is mounted on a carriage (26) which has a spacer member (50,52) secured to it to contact the top surface (16) of a document to be printed on. The spacer member (50,52) causes the print surface of the platen (28) to tilt causing ink smears or uneven printing by the print head (24). A stabilizer is used to prevent tilting of the platen (28) caused by the member (50,52) to thereby maintain the printing surface of the platen (28) in parallel relationship with the print face of the print head (24), which in the embodiment described, is a wire matrix printer. The stabilizer includes first and second leaf springs which are secured to the platen (28) and cooperate with side wall of a channel (38) in which the platen (28) is mounted. <IMAGE></p> |
