Print Head Balance - SATO S8412 Operator's Manual

PRINT HEAD BALANCE

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 characteristics.
To adjust the balance, begin test printing, slightly loosen set screw (1, Figure 6-11), and slightly move the
adjustment plate (2) upward or downward as necessary. Retighten set screw (1) while holding the adjustment plate
(2) when proper printing is achieved.
