image and the edge of the paper. 

No adjustment is needed if the difference between these dimen-
sions is within 0.5 mm.

[Check Method 2]

Check the printed grid pattern for distortions. 

If the right-angle level of the traverse print line is 0.5mm or less with
respect to the longitudinal print line of paper, no adjustment is needed.

Carry out the following work if the situation is unsatisfactory.
