6. Measure the left margin of the test print.
If the left margin is 2 mm (0.08 inches), you do not have to adjust the

calculate the difference. Use this measurement to adjust the registration
with the side registration adjustment dial.
Example
When the left margin is 2.8 mm
2.8 mm – 2.0 mm = 0.8 mm (Decrease the margin by 0.8 mm.)
0.8 mm
÷
0.4 mm = 2 (Decrease the dial value by 2.)

If the margin is still not 2 mm (0.08 inches), repeat step 6 through step 8.
