Resetting the setting to [Off] due to change in paper type or operating environment may also avoid
vertical streaks appearing on the printed paper. In this case, reset the setting to [Off].
If you specify this setting, printing speed drops.
1. Display the [Finishing] tab.
2. Click [Advanced Settings].
3. Set [Special Print Adjustment A] to [Mode 1].
If the problem is not solved, specify [Mode 2].
If the problem is not solved, specify [Mode 3].
If the problem is not solved, specify [Mode 4].
Resetting the setting to [Off] due to change in paper type or operating environment may also avoid
vertical streaks appearing on the printed paper.
In this case, reset the setting to [Off].
Vertical streaks are alleviated by specifying a setting between [Mode 1] and [Mode 4]. However,
this decreases print density compared to when [Off] is specified.
This may also make outlines appear to be blurred or slightly jagged.
If outlines are jagged, select [Off].
