Banding defects
Description
Repetitive wide-pitch banding and Impulse bands:
Dark or light lines which repeat down the length of the page. They might be sharp or soft in nature. The defect displays only in areas of fill, not in text or sections with no printed content.
Possible solutions
- Reprint the document.
- Try printing from another tray.
- Replace the cartridge.
- Use a different paper type.
- Enterprise models only: From the Home screen on the printer control panel, go to the Adjust Paper Types menu, and then choose a print mode that is designed for a slightly heavier media than what you are using. This slows the print speed and might improve the print quality.
