Hi @dee_ar-em1,

Welcome to The HP Support Community.  

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

I understand you are trying to change the paper size from 5x7 to 8.5x11 on your HP ENVY Pro 6400 All-in-One Printer, follow these steps:

On Windows (through the HP Smart app or Printers & Scanners settings):  HP printer setup (HP Smart app)

1. Open the document you want to print.
2. Go to File > Print.
3. Select your HP ENVY Pro 6400 printer from the list of printers.
4. Click on Printer Properties or Preferences (the exact wording may vary).
5. Look for the Paper/Quality tab (or similar) and select it.
6. In the Paper Size dropdown menu, select 8.5 x 11 inches (or "Letter").
7. Click OK to save the changes and return to the print dialog.
8. Now, click Print to start printing on 8.5x11 paper.

On Mac:

1. Open the document you want to print.
2. Go to File > Print.
3. From the printer options, select your HP ENVY Pro 6400.
4. Click on the Show Details button if necessary.
5. In the Paper Size dropdown, choose 8.5 x 11 inches (or "Letter").
6. Click Print.

Check the Printer’s Physical Paper Settings:

1. Open the paper tray on the printer.
2. Adjust the paper width guides to fit 8.5x11 paper.
3. Ensure the paper is loaded correctly and that there is no paper jam or misalignment.

This should resolve the issue, and your printer should now print on 8.5x11 paper.
