CAUTION: Do not turn the head adjust screws more than 2 turns in either
direction. Damage to the head mount assembly could result if the
adjustment screws are turned too far.
Print a label and inspect the printing quality. With a 1/16" hex key, turn the left and
right head adjust screws counter-clockwise 1/4 to 1/2 turn until the desired print
quality is achieved. Finally, turn the left head adjust screw 1/4 turn counter clockwise.
Direct Thermal Adjustment
For best results when using thermal label stock, turn the head adjust screws 1/4 turn
clockwise, to move the printhead 6 thousands of an inch back on the roller. When the
printhead is aligned with thermal transfer operation in mind the printhead should be
forward on the roller so the ribbon will separate from the label while the wax/ink is still
warm. With direct thermal operation, the printhead burn line needs to be back further
on the roller. This will create a higher pressure on the roller and thus heat will transfer
to the label stock more efficiently.
2.4.2 RIBBON FEED AND TRACKING ADJUSTMENTS
1. Turn power switch to the ON position. Use full-width media and ribbon for this
adjustment procedure.
2. Install thermal transfer ribbon and media into PA/4000, but do not secure the
ribbon to the ribbon rewind hub.
3. Press the FEED button several times to normalize the feeding of the ribbon and
media. Check the distance from the center plate to the edge of the label backing,
this should be the same distance as it is back where labels come of the roll of stock
(about 320 thousands of a inch). If this is within about 30 thousand of an inch,
proceed to step 5.
4. Open the Electrical Box Assembly to expose the electronics compartment. Locate
the Phillips screws holding the label guide standoff. Loosen, but do not remove
the screw. On the label side of the PA/4000 adjust the hex set screw that comes in
contact with the center plate. This will raise or lower the extrusion and adjust the
flow of the labels which will adjust the tracking of the labels. If the labels are
tracking too much toward the centerplate, ribbon wrinkle may occur.
5. Press the FEED button several times to normalize the feeding of the ribbon and
media. Observe if there is any "rippling" or "bagging" of the ribbon as it comes
from the supply hub and goes under the printhead assembly. If there is rippling
or bagging, the supply hub needs to be repositioned. If there is no rippling or
bagging observed, go on to Step 10.
