Zebra Technologies S-300 Printer User Manual


 
When the Power Roller is properly adjusted, the backing material should have even
tension across its entire width and be wrapped snugly around all Guides and Rollers. If
the tension is not even, the media/backing material may slide (walk) to the left or to the
right as printing occurs. This can cause print registration problems on the labels.
Figure 26 illustrates an improperly adjusted Backing Rewind Power Roller. On the left
side, the backing material is not contacting the Power Roller. The backing has more
tension on the right edge than on the left edge.
Use a coin or screwdriver to turn the Power Roller Adjustment.
The Adjustment Mechanism changes the position of the right end of the Roller, while
the left end is stationary. The right end moves up and down for tension balance.
Turning this Adjustment in a counterclockwise direction causes the right end of the
Power Roller to move DOWN and increases the tension on the right side of the backing
material. (Turning the Adjustment in a clockwise direction moves the right end of the
Power Roller UP and decreases the tension on the right side.)
Balancing the tension increases the reliability of the printer to provide properly printed
labels by preventing the label backing from walking.
Use the FEED Key Self Test (see Chapter 4) or your own label format to print several
labels to insure tracking is maintained and tension on both edges of the backing material
remains consistent. Remember to remove each label as it is automatically peeled away
from the backing.
Battery Replacement
Your printer may be equipped with Battery Backed-Up Memory. The battery used with
this feature is a 3 VDC lithium battery.
