feed units and check the amount that the image is shifted.
2. Adjust by changing the contents of the following addresses:
Source Address

3. To move the start position to the right, increase the value.
To move the start position to the left, decrease the value.
For example:
•
To move the start position to the right 2 mm (with respect to the default
value):
0002H + (2 / 0.5) H = 0006H
•
To move the start position to the left 1 mm (with respect to the default value):
0002H - (1 / 0.5) H = 0000H
