15. Slacken the M8 nuts (3) directly below the front and rear transit brackets (2).

16. Adjust the M8 nuts (3) above the front and rear transit brackets (2) to lift the

roller counter plates off the roller bearings (in all four positions), ensuring

that the roller counter plates are not touching the chase clamps.

17. Tighten the M8 nuts (3) directly below the front and rear transit brackets (2).

Cover Frame

Transit Bracket

This bracket is to be fitted to printers with Anti Vibration (AV) mounts fitted to the

cover frame. It is located between the frame (adjacent to the print illumination

lights) and the carriage rail. There are neoprene washers stuck to the frame in

the position the transit bracket is to be fitted (See vignette in graphic below).

1. Ensure mating surfaces are clean and free of debris.

2. Place the cover frame transit bracket (1) and the block (6) (as an assembly)

over the carriage rail. The M5 screws (7) along with the crinkle washers (8)

and washers (9) should be sufficiently loose to allow adjustment.

3. Locate the M5 cap head screws (2) along with the crinkle washers (3) and

washers (4) through the bracket and into the frame and leave sufficiently

loose to allow movement.

4. Raise or lower the bracket (1) so it abuts the frame to achieve best fit and

the block is level on the carriage rail.

5. Tighten the M5 cap head screws (2).

6. Tighten the M5 cap head screws (7)
