If you have rotated or reassembled the rear CR guide shaft or parallelism adjustment bushing, or if printing is
light or dark, even at the proper PG lever position, perform this adjustment at 3 positions: the 5th, 80th, and
130th columns.
1. Remove the printhead from the CR assembly (see Section 3.2.3).
2. Remove the ribbon mask from the ribbon mask holder using tweezers, as shown in the figure.
3. Attach the printhead to the CR assembly again, tightening the 2 CBS screws (3 × 10, F/Zn).
4. Move the printhead to 5th column position.
5. Set the release lever to the FRICTION position.
