ADJUSTMENT PROCEDURES

This chapter covers all of the printer and printer accessory adjustments. These adjustments include mechanical adjustments required following the replacement of components and assemblies, in addition to, the operational adjustments required following a job change.

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 set screw (1, Figure 6-4), and slightly move adjustment plate (2) to the right or left as necessary. Retighten set screw (1) while holding adjustment plate (2) when proper printing is achieved.
