No

If the problem persists, set [Process Speed Setting] in 1331: [Motor Speed] to [Standard Speed], then proceed to "Procedure 3: Adjusting intervals between sheets".

Procedure 2: Adjusting intervals between sheets

1In [Advanced Settings] for the custom paper, select 1331: [Motor Speed], and then adjust the value in [Paper Feed Interval Setting].

Adjust the length of intervals between sheets to move streaked areas to areas with no print image or intervals between sheets. For instance, when performing black-and-white printing on A3 paper, set this value to 54 percentage points to move the streak to the interval between sheets.
