2.2.5 Platen Gap Adjust Mechanism

The platen gap adjust lever, attached to the left upper side of the printer cover, should be set to the
appropriate position for the paper thickness. The platen gap adjust mechanism consists of the platen
gap adjust lever, carriage guide shaft, and two parallelism adjust bushings. Switching the lever
between positions 0 and + rotates the carriage guide shaft toward the front or rear. The bushings have
an eccentricity toward the center of the carriage guide shaft, and the platen gap is changed from wide
to narrow or vice versa.
