Hi! @Bel73, Thanks for stopping by the HP Support Community!

Don't worry I'll try to help you out.

Have you tried checking with a different toner cartridge?

Does the issue persist when you when you make a copy from the printer?

Have you tried printing from a printing application?

Replace low, empty or faulty toner cartridges on the printer

Try few steps recommended below.

Check the print settings on a computer with Windows.

1. In the software application you are trying to print from, click File, and then click Print.

   The Print window opens.

2. Open the Properties dialog box.

   Depending on the software program, the button might be Properties, Options, Printer Setup, Printer, or Preferences.

3. Depending on your print job, you might consider modifying the following settings:

   • Paper Type: Select the appropriate type of paper, such as photo paper, plain paper, or labels.

   • Print Quality: Increase the print quality from Normal or Draft mode to Best.

   • Paper Size: Select the correct paper size for your print job.

4. After changing the print settings, click OK to apply the settings, and then click Print.

Print a cleaning page

The printing mechanism and printing path inside the printer might need to be cleaned to resolve issues like repeating dots, fuzzy print, or smeared toner.

1. From the Home screen on the printer control panel, swipe left, and then touch Setup.

2. Touch Service, and then touch Cleaning Page.

3. Load plain, white paper when you are prompted.

4. Touch OK to begin the cleaning process.

5. Try to print again to see if the issue is resolved,
