Image defect details
• The media does not meet HP specifications.
• The toner cartridge is defective.
• The inside of the printer is dirty.
• The transfer roller is dirty or worn. Generate a cleaning page.
Banding occurs when solid fill areas show streaks or bands of shade
variations. This can be caused by:
• Worn, damaged, or contaminated gears
• Consumables that are beyond their rated life
• Improper consumable storage
If the problem persists:
• Print a configuration page to check the life of the consumables.
Replace any consumable that is past its rated life.
• Banding is more visible in some halftone patterns than in others.
Print a page using a halftone pattern such as “banddiag” provided in
the Color Smart selection in the printer driver. If the defect occurs
only once on a letter-size sheet, try printing the pattern on a legal-
size sheet.
