Striped Patterns Appear

When printing on plain paper, disable the bidirectional setting.

During bidirectional (or high speed) printing, the print head prints while moving in both directions, and vertical lines may be misaligned. Disabling this setting may slow down printing speed but improve print quality.

Select Settings > General Settings > Printer Settings, and then disable Bidirectional on the control panel.

Use the Print Quality Adjustment feature. If you have not used the printer for a long time, the print head nozzles may be clogged and ink drops may not be discharged.
