• When Print Mode is B/W: 85/106/141/200/300
When Print Mode is changed, the screen frequency returns to the initial value. The initial values
are 120 for Color and 106 for B/W.
When Error Diffusion is selected, the Screen Frequency is fixed to 120 for Color and 106 for B/W.
When PS/PDF is selected
If the print mode is the same for both Upstream and Downstream, the setting value for
Upstream is used for Downstream and the screen frequency for Downstream cannot be
operated. If the print mode is different for Upstream and Downstream, the set frequency for
Upstream is displayed. The following table shows the screen frequencies.
