How do I fix streaks or smudges on my printed documents?

1. Check if the issue is happening because of a low ink level in the printer.
2. If the there is enough ink, clean the printer head.
3. Run the ‘head cleaner’ tool within the printer settings.
4. Wipe the printer head with a non-abrasive tissue and a small amount of alcohol.
5. Check if the issue is resolved and print a test page.
