Assembly Technique

A new technique for assembling maching frames requiring the maintenance of close tolerances is described.

It has been found that providing a fixture for holding the bottom plastic cover of a printer frame and one or two guide shafts allows a unitary molded side frame piece to be connected to the location of the printer using a potting material. The guide shafts fit in the opening made by appropriately configured recesses in the raised portion of the cover and molded side frame piece. In this way, the frame is assembled in a stress-free condition.

In a similar fashion, the relative position of the carrier to the platen may be established in a manner requiring no assembly line adjustments. The carrier assembly is first completed and attached to the other of two guide shafts in the printer. This guide shaft carrier assembly is positioned in a fixture designed to maintain the proper relationship with the platen and potted in position. The result is that tolerances are maintained in the entire assembly, thereby eliminating previously required adjustments
