Optimizing and Maintaining Print Quality
Intermec designed and configured the printer to provide the best possible
print quality for both direct thermal and thermal transfer media. If
necessary, you can manually adjust the printer to perform registration tasks
such as correcting uneven print quality.
Correcting Uneven Print Quality
You may experience problems in print quality (ribbon wrinkling or light
print on one side of the label) if the printhead is not making even contact
with the label stock. This condition can happen with any size label stock,
but is most common when using narrow label stock.
To achieve the best print quality, adjust the bias adjust screw each time
you use media of a different width.
Note:
You must properly adjust the bias adjust screw to prevent premature
printhead failure and excessive platen wear.
To adjust the bias adjust screw
