Perform the following procedure in the printer driver.
1. Display the [Finishing] sheet.
2. Click [Advanced Settings].
3. Set [Special Print Adjustment A] to [Mode 2].
If the problem is not solved by specifying [Mode 2], specify [Mode 3].

* Vertical streaks are alleviated by specifying [Mode 2] to [Mode 4]. However, this decreases print density compared to when [Mode 1] is specified. This may also make outlines appear to be blurred or slightly jagged.
