PRINT HEAD BALANCE ADJUSTMENT
Print head balance is the equalization of pressure against the platen roller from one end to the opposite. If the print
head balance is out of adjustment, the printed image will be darker on one side of the label than the other and the
media will be prone to travel in the direction of least resistance.
The adjustment of print head balance on the label can be subjective. One will know when balance is achieved by
the disappearance of prevailing negative print characteristics.
To adjust the balance, begin test printing, slightly loosen the set screw, and slightly move the adjustment plate to
the right or left as necessary. Retighten the set screw while holding the adjustment plate when proper printing is
achieved.
