Abstract
The mechanism herein relates to the automatic positioning of the print mechanism with respect to the forms and ribbon in a printer assembly. The automatic adjustment takes place for varying thicknesses of the forms, which is a function of the number of copies being printed and the type of form, as well as the variations in the thickness of the ribbon. The abovementioned adjustment takes place after there has been a simulation of the print hammer striking the paper which may be a single-part or multi-part form. Simulation is obtained by extending a probe to deform the forms in the same manner as a print hammer deforms the forms in the actual printing operation.
