Print Potentiometer
The fine adjustment for Print Darkness is the PRINT 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.
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
either the Print Speed command code or the LCD display panel. 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.
The Print Speed can be set to 2, 4, 6, 8 or 9 inches per second (with DSW2-8 OFF) or
2, 4, 6, 8 or 10 inches per second (DSW2-8 ON) using the LCD panel (see page 26) or
using software. The software command will override the any setting entered using
the LCD panel.
