leading edge of the wide bars should also

darken until they are solid all the way across.

7. Vary the MEDIA_ADJUST value in large

increments (about 500) and print the test label
until the printed bar code approaches the

appearance described in step 6. Change
MEDIA_ADJUST

in smaller increments as you

begin to see improvement in the print results.

After achieving satisfactory visual results, you may
want to scan the bar codes with a bar code verifier. No

further adjustment is required if the bar codes scan
satisfactorily. The experimentally derived value will

work with all media that has the same temperature
response. You may send the new MEDIA_ADJUST

value to the printer with VARIABLE WRITE as shown

in the example below, or simply note the value for
future reference.

NOTE: This method should provide optimum rotated bar
code reliability, but may not produce visually pleasing
labels. Labels that "look good" are often too dark for good
bar code performance. You may want to increase the print
darkness for attractive text and graphics.
