Figs. 1-3 illustrate several views of the present mechanism. A clip-on nose wheel bracket also serves as a retaining clip to hold the print head in a carriage. Movable carriage dot matrix print heads and the like often require variable form thickness adjustment control. A typical adjustment is to provide a compression wheel that is mounted to the print head which is spring loaded against the printer platen and documents over the platen. As the carriage traverses the printing field across the platen, the roller bears against the document and pushes the print head backward against spring-loaded pressure in the event the document is thicker. Fig. 1 illustrates a semi-pictorial view of a schematic of the present design. The print head 1 is mounted to a carrier 2 for traversing a print line in a printer.
