The fine adjustment for Print Darkness is the VR1 potentiometer on the operator
panel. It provides a continuous range of adjustment, allowing you to make precise
changes. Use a small cross-point screwdriver, turning clockwise for darker print and
counterclockwise for lighter print. See Section 2: Installation and Configuration for
instructions on performing potentiometer adjustments
NOTE: The PRINT potentiometer adjustment will affect the darkness in all of the
command code speed ranges, i.e. if the PRINT potentiometer is adjusted for lighter
print, the darkness will be lighter in all speed ranges selected by the command code.
Print Speed
The other method of controlling print quality is by controlling the speed at which the
label is printed. This adjustment is made only on an individual label basis using the
<ESC>CSPrint Speed command code. For more details on this command, see Section
4: Programming. Changing the print speed allows the user to control the amount of
time allowed for print element cooling before the media is stepped to the next print
position. It is especially critical when printing “ladder” bar codes (bar codes printed
with the bars parallel to the print line). When printing a “ladder” bar code, it is
important to allow the head to cool sufficiently before stepping to the next position. If
it does not have sufficient time to cool, the bar will be “smeared” on the trailing edge.
