Hi @Nirala3,

Welcome to HP Support Community.

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

If your HP OfficeJet 790 printer is constantly showing an "ADF Jam" error despite clearing the paper, it typically indicates a problem with the Automatic Document Feeder (ADF) mechanism. Here’s a step-by-step guide to troubleshoot and resolve this issue:

1. Power Cycle the Printer

Turn Off the Printer:

• Press the power button to turn off the printer.

Unplug the Printer:

• Disconnect the printer from the power source.

Wait and Restart:

• Wait for about 60 seconds, then plug the printer back in and turn it on.

2. Inspect the ADF for Paper Jams

Open the ADF Cover:

• Gently open the ADF cover to access the paper path.

Remove Any Visible Paper:

• Carefully remove any paper or debris from the ADF area. Check for any torn pieces of paper that might be stuck inside.

Check the Paper Rollers:

• Inspect the rollers for any paper fragments or obstructions. Clean the rollers gently with a lint-free cloth slightly moistened with distilled water if they are dirty.

3. Check and Reset the Paper Path

Remove the Input Tray:

• Remove the input tray from the printer and check for any paper or obstructions in the tray area.

Check the Output Bin:

• Ensure that the output bin is clear of any paper and that it is properly seated.

Reinsert the Paper Tray:

• After checking and clearing the paper path, reinsert the input tray and ensure it is properly aligned.

4. Inspect and Clean the ADF Mechanism

Check the ADF Rollers:

• The ADF rollers can accumulate dust or debris. Clean the rollers using a lint-free cloth.

Inspect the ADF Separator Pad:

• The separator pad helps to separate individual sheets of paper. Check it for wear or damage and clean it if necessary.

Check for Obstructions:

• Look for any foreign objects or debris in the ADF mechanism that might be causing the jam.

5. Perform a Paper Feed Test

1. Run a Paper Feed Test:
   • Load a few sheets of paper into the input tray.
   • Use the printer’s control panel or the HP Smart app to run a test scan or copy to see if the paper feeds correctly through the ADF.

6. Reset Printer to Factory Settings

1. Factory Reset:
   • If the issue persists, consider performing a factory reset on the printer. This will restore the printer to its default settings.
   • Refer to your printer’s manual or the HP Support website for instructions on how to perform a factory reset.

I hope this helps.

Take care and have a good day.
