printed text is wavy (as if page is not flat during printing)

[DainaTi]

For months my HP OfficeJet 4650 printer has worked fine. Now, all of the sudden, my text alignment on the printed page is in an "S" pattern all the way down the page. Like the printing surface is not flat.in the text doc everything is aligned

Hi @DainaTi 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your HP OfficeJet 4650 is printing text in a wavy pattern, it can be caused by several issues. Here are some troubleshooting steps you can try:

1. Check Paper Type and Quality

• Make sure you are using the correct paper type for your printer. Ensure that the paper is flat and not curled or damaged.

2. Check Paper Feed

• Ensure that the paper is loaded correctly in the tray. The guides should be snug against the paper, but not too tight.

3. Run Print Quality Diagnostic

• Print a diagnostic page to check for issues:
  • Go to Setup > Tools > Print Quality Report.
  • Review the report for any patterns or misalignment.

4. Clean Printheads

• Run the printhead cleaning function to clear any clogs:
  • Go to Setup > Tools > Clean Printheads. Follow the prompts.

5. Align Printheads

• After cleaning, run the printhead alignment:
  • Go to Setup > Tools > Align Printheads.

6. Check for Firmware Updates

• Make sure your printer firmware is up to date. You can check for updates through the HP Smart app or the HP Support website.

7. Inspect for Hardware Issues

• Check for any visible damage or obstructions in the printer. Make sure there’s no debris in the paper path or around the rollers.

8. Test with Different Paper

• Try printing on a different type of paper to see if the issue persists. Sometimes, low-quality paper can cause printing problems.

I hope this helps.

Take care and have a good day.
