Adjustment Parallel adjustor 118
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.
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
mechanism frame.

2. Set the lever and PG to the (-) position at the front.
3. If the carriage unit is locked, use a pair of pincers to press down on the lock lever
and release it.
