Figure 24 illustrates an improperly adjusted backing rewind power
roller (a). On the left side, the backing material (b) is not contacting the
power roller. The backing has more tension on the right edge (c) than on
the left edge (d).
Use a coin or screwdriver to turn the power roller adjustment (e). 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 Troubleshooting) 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.
