Adjusting The Print Contrast - Monarch 9800 Series Operator's Handbook Manual

A d j u s t i n g t h e P r i n t C o n t r a s t
You may need to adjust the print contrast if the printing is too light
or too dark. Having the correct print contrast is important
because it affects how well your bar codes scan and how long
your printhead lasts.
Using a thin screwdriver, turn contrast knob clockwise for darker
print; turn counter-clockwise for lighter print.
You only have to turn the contrast
adjuster slightly.
Your System Administrator can adjust the print contrast by
sending the print control packet. Refer to the Packet Reference
Manual for more information. We recommend you check the bar
code print quality with a bar code verifier. If you do not have a
bar code verifier or
scanner, check the bar
code visually. A bar code
that is in spec has
complete bars, clear
spaces, and small
alphanumeric characters
look complete. An in
