Print Quality Problems
The Infoprint Color 8 is really four printers in one—one for each of the three primary colors
and one for black. The factors causing print quality problems may affect only one or two
colors, or all four, so the results may be unpredictable.
If you notice fuzziness or changes in color balance that are not connected to a particular
software package, check the symptoms and possible causes in this section. You can use the
color bars at the bottom of the menu test printout to help isolate which color is causing the
problem.
