5.2 Parallel adjustor

As it is necessary to temporarily remove the bushes and parallel adjustor when
disconnecting or replacing the carriage unit, parallel adjustments are required.
Parallel adjustments include the parallel adjustment of the axes, the CR, the guide and
the surface of the paper, and the PG adjustments (platen gap) that set the gap between
the platen head and the platen surface to a fixed distance.
Do not scratch of otherwise damage the specially coated surfaces
of the roller and PF unit, the paper guide, or the surface of the
front rib.
Clean the gap gauge with a cloth moistened with alcohol prior to
performing the parallel adjustment procedures.
Do not scratch or otherwise damage the surface of the printer
head, or leave it soiled (do not used dirty gap gauges.) Also,
make sure the gap gauge does not come into contact with the
surface of the head.)
Ensure that parallel adjustments are performed with the in
cartridge mounted in place.
Adjustment
1. Ensure that the mark on the bush is aligned with the protruding part of the frame
when attaching the left and right bush and parallel adjustor to the printer's
