ABSTRACT:
A platen gap adjuster for a printer utilizes a shaft along which the print head carriage slides during printing of each line. The shaft is eccentrically mounted by means of unitary, offset spindles the common axis of which is parallel to but spaced from the shaft axis. By rotating the shaft about the common spindle axis, the carriage and print head will be moved transversely of the shaft, thereby adjusting the gap between the print head and platen without impairing the longitudinal sliding motion of the carriage.
