In conventional wire matrix printers, it is necessary to adjust the head-to-platen distance to compensate for varying thickness forms. In the past, this has been done by attaching the paper thickness knob and its standoff bushing to the head adjustment bracket with a binding head screw. The bracket assembly was then attached to the carrier casting with a binding head screw which passes through a slot in the bracket. With the knob set at zero, "the bracket assembly is pushed up against the feeler gauge, which has been inserted and held between the printhead and platen, and the bracket assembly is then tightened in place.
