printer issue: streaks

[XX6595]

If streaks appear in multiple color bands, contact HP. A component other than a cartridge is probably causing the problem.

Thank you for posting, however you need to include more details to make it possible for someone to provide guidance. The list below is a generic list of possible information to provide and some may not be applicable in your case.

-Be sure to include model of printer
-operating system of computer
- printer driver installed
- printer connected via WIFI, Ethernet or USB?
- has it ever worked?
- any error messages appearing on the screen including numeric or text errors.
- anything that may happened just before the error started such as paper jams or power failures.
- If you can include a sample that would help when issue is print quality

Thank you for your response. Here are more details:

• Printer model: HP Color LaserJet Pro 3201
• Connection: Ethernet
• The printer was working normally before this issue started.
• There are no error messages on the printer.
• I’m not aware of any paper jam or power failure immediately before the issue started.
• The problem is print quality: there are many dense black vertical lines along one side of every printed page.
• The same lines also appear on the printer’s own Print Quality Troubleshooting Page, so the issue does not appear to be related to the computer, driver, or document being printed.
• The streaks appear across multiple color bands on the Print Quality Troubleshooting Page.
• I already ran the cleaning/fuser cleaning process, but there was no improvement.

I’ve attached a photo of the Print Quality Troubleshooting Page showing the issue.

Based on the troubleshooting page, it states that if streaks appear in multiple color bands, a component other than a cartridge is probably causing the problem. Could you please advise what component I should check next, or whether this printer needs service?

Thank you for your help.
