- Same direction of the tail ends
When installing the coded scan bodies, we need to ensure the tail ends point to the same direction to form a fan shape. If there is inadequate space, it is also acceptable to arrange the coded scan bodies along the residue ridge.
- Appropriate Gap
It is necessary to keep proper gaps among coded scan bodies.
If the gap is extremely distant, it is difficult to get a smooth transition in the scanning stage.
If the gap is extremely closed and cause some overlaps, it will lead to a failure of recognition and poor accuracy.
