While printing, adjust the eccentric with a 10mm wrench. Turn the
eccentric clockwise to increase the density (darker impression) of the inner
side of the image or counter-clockwise to increase the density (darker
impression) of the outer side of the image.
Hold the eccentric in place with the 10mm wrench and tighten the locking
screws loosened in Step 3 above.
After adjustment, verify that label and ribbon are still tracking correctly.
If you are unable to get the unit to produce good print quality, return to
Section 5.3 Print Head Position Adjustment and perform the adjustment;
then return to this section and redo the Print Head Balance Adjustment.
NOTE: You may have to do both of these adjustments concurrently
several times to achieve proper print quality and alignment.
