Print Density and Resolution Enhancement
The print densi~ adjustment (see Chapter 4, Section 4-9) setting interacts with Resolution
Enhancement.
For any resolution enhancement level, adjusting the print density may place too
much or too Iitie toner at the transition poinfi along gradudly sloping lines. A slight bulging or
pinching effect may be seen if tie lines are examined closely. The following drawings illustrate
how the line transitions appear with different amounti of toner:
Figure 3-3. PrintDensity at Line Transitions
1. Normal line transition.
2. Too much toner; set RETin the Control Panel Configuration Menu to a lighter setting.
3. Too litie tone~ set RETin the Control Panel Configuration Menu to a darker setting.
Check the adjustment by examining a self-test printout (see Figure 3-4 for an enlarged portion of
the printout). Look at the 33% slice in the pie chart. If light vertid stripes appear (see lefi side),
try setting RETto the nefi darker setiing. If dark vertid stripes appear, try setting RETto the
next lighter setiing. If the output still has dark vertid stripes (see right side), adjust the print
density did to a slightiy lighter setting (a higher number on the print densi~ did) and repeat the
adjustment.
