Setup Phase (Steps 1 - 6); Printhead Gap Modification Phase (Steps 7 - 9); Parallel Adjustment Phase (Steps 10 - 12); Check Phase (Steps 13 - 16) - OKIDATA Pacemark 3410 Service Handbook

This adjustment has four phases.

1. Setup Phase (Steps 1 - 6)

The cover is removed and the printhead is placed at a known reference point.

2. Printhead Gap Modification Phase (Steps 7 - 9)

The distance between the printhead and the platen at the left (line feed motor)
side of the platen is modified by rotating the left eccentric collar. Rotating
the eccentric collar varies the position of the carriage shaft relative to the
platen.

3. Parallel Adjustment Phase (Steps 10 - 12)

The right eccentric collar is rotated to ensure that the printhead moves parallel
to the platen (at the correct gap setting).

4. Check Phase (Steps 13 - 16)

This phase verifies that the Parallel Adjustment Phase did not affect the
Printhead Gap Modification Phase.
