Vertical Streaks Appear on the Output

Try one of the following to solve the problem.

<Cause 1> Due to the paper type or usage conditions, vertical streaks appear on the output.

Solution 1
Replace the paper stack with new unopened one.
Solution 2
To copy
Change the <Special Mode Z> setting from the operation panel.
To print from USB Direct Print or a computer
For USB Direct Print, change the <Special Mode X> setting in the operation panel.
To print from a computer, change the [Special Print Adjustment] setting in the print driver.
The effect becomes greater as the number goes up.
<Off> -> <Mode 1> -> <Mode 2> -> <Mode 3>
(low)
(high)
Streaks can be minimized by changing the paper type or usage conditions, without needing to change the setting.
The more effective the setting, the lower the density becomes. Additionally, the outline of text and images may be reproduced less clearly, and images may appear slightly jagged.
If you cannot solve the problem even setting <Special Mode X>, set <Special Mode D> to <On>.
Solution 3
To print received faxes or the print report
Change the <Special Mode C> setting to <On> from the operation panel.
To apply the solutions to all the jobs
Change the <Special Mode D> setting to <On> in the print driver.
Streaks can be minimized by changing the paper type or usage conditions, without needing to change the setting.
If you set this option to <On>, the printing speed will be slow.

<Cause 2> The toner cartridge was replaced recently, or the machine has not printed anything for an extended period of time.

Solution
Change the setting of <Special Mode B> from the operation panel.
The effect becomes greater as the number goes up.
<Off> -> <Mode 1> -> <Mode 2> -> <Mode 3>
