ABSTRACT:
A printer employing a movable print carriage is fitted with a single rigid bar-like carriage support structure having three very narrow, low friction, plain guideways, either grooves or rails, kinematically arranged for extremely accurate guiding of the printing carriage as it moves along the writing line. The print carriage is fitted with kinematically arranged mechanically reciprocal guides for engaging the guideway grooves or rails. The carriage support structure is made sufficiently rigid and massive to also serve as the printer frame for supporting the platen and other printer parts and elements. The location of the three guideways, primary feed roller bearing supports, platen supports, and platen adjustment rod bearings are such that all can be machined in one set-up in a multiple spindle machine tool so as to achieve exact parallelism of all the elements requiring precise alignment.
