6.3 Pr i nthead Burn Line Adjustment
The Burn Line has been adjusted at the factory for strict compliance using 6.5-mil (.0065 inch) media, ensuring print
qua lit y a c r oss a major it y of media typ es. I n ext r eme ca s es, however , if media of a differ ent thic kness or r igidit y is u s ed ( for
example, heavy tag stock), print quality can change. Typically, thicker media requires a slight forward adjustment, while
t hinner media requires a slight backward a dju stment.
