5.1 Printhead Adjustments
To ensure consistent print quality over a wide range of media types and
dimensions, the printer is equipped with a Leveling Cam adjustment and a Burn
Line adjustment.
5.1.1 Leveling Cam Adjustment
When printing on less than full width
media, use the Leveling Cam to adjust the
right side of the Printhead Assembly for
even pressure distribution. To adjust the
Leveling Cam:
n With media loaded in the printer,
download your label format (or use a Quick Test format) and begin batch
printing.
o While observing the printed labels, rotate the Leveling Cam counter-
clockwise to an over-adjusted position (see Example 1, below).
p Next, rotate the Leveling Cam clockwise, one click at a time, until the
printed labels contain a complete, even image (see Example 2).
☞
When changing to a different width of label, readjust the Leveling Cam.
Example 1 – Over adjustment:
Too much adjustment produces an image that
fades across the label. To correct this,
decrease the setting of the Printhead Leveling
Cam.
Example 2 – Correct adjustment:
The proper adjustment produces a complete
image with even print contrast across the
label (see note below).
;
Note: Under-adjustment of the Leveling Cam: Problems can include ribbon
wrinkling, label tracking, and platen roller and printhead wear.
