Where are the rubber rollers to clean

[Bones877]

Printed an invitation.  Reinserted to print on back side, and didn't realize ink was not dry.  Now getting 2 dark smudges on everything I print.  I opened printer and found some rollers and cleaned, but did not help. Where are the rollers to clean them?

Welcome to the HP Support Community. 

Let's perform a clean ink smear diagnosis:

1. Load plain white paper in the input tray.

2. On the printer control panel, swipe down to open the Dashboard, and then touch the Setupicon.

3. Swipe up on the display, touch Printer Maintenance, and then touch Clean Smear.

   The printer feeds one page slowly. The printer might make some noise for approximately one minute.

4. Wait until the page is out of the printer before you remove it.

After cleaning ink smears, try to print.

Also, please follow Step 3 from this document: https://support.hp.com/us-en/product/hp-envy-photo-7800-all-in-one-printer-series/9073159/model/9073...
