ABSTRACT:
An adjustable carriage assembly for a printing device having a print mechanism to be translated along a linear print path. The carriage assembly includes an upper carriage sub-assembly and a lower carriage sub-assembly, the lower carriage sub-assembly having a pair of laterally spaced arm members joined together by a pair of cross members. Each arm member has an open pivot slot and a support ramp portion. A spring coupled between the upper and lower carriage sub-assemblies in the region adjacent the pivot portions provides a spring detent for the upper carriage sub-assembly with respect to the lower carriage sub-assembly in both the first operative position and a second inoperative position. The guide members are adjustable eccentric washers.
A cartridge latch is configured to be removably mounted in an aperture formed in a platform on the upper carriage sub-assembly. The latch comprises a unitary member having a lower U-shaped portion with one leg terminating at an upper end in an outwardly extending flange and the other leg having an outwardly extending keeper nib located below oppositely extending flange portions and spaced therefrom, an upper portion having a cartridge abutment surface, and a relatively stiff web portion joining the upper portion to the top surface of the flange portions.
