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.
Solutions
Do not load more than the maximum number of sheets specified for the paper. For plain paper, do not load above the line indicated by the triangle symbol on the edge guide.
Solutions
Place the paper on a flat surface to check if it is curled. If it is, flatten it.
Solutions
Check the paper condition. If paper absorbs moisture, it becomes wavy or curls that may cause the trouble.
Solutions
If papers are smeared or scuffed frequently, try using newly opened papers.
Solutions
When printing on thick paper, the print head is close to the printing surface and the paper may be scuffed. In this case, enable the reduce scuff setting. If you enable this setting, print quality may decline or printing may slow down.
Control panel
Select Settings > General Settings > Printer Settings, and then enable Thick Paper. See the printer's LCD screen for the setting options.
Solutions
If paper is still smeared after enabling Thick Paper, reduce the print density.
