Solutions
When horizontal banding (perpendicular to the printing direction) appears, or the top or bottom of the paper is smeared, load paper in the correct direction and slide the edge guides to the edges of the paper.
Loading Paper in the Rear Paper Feeder
When vertical banding (horizontal to the printing direction) appears, or the paper is smeared, clean the paper path.
Cleaning the Paper Path for Ink Smears
Place the paper on a flat surface to check if it is curled. If it is, flatten it.
