ADF on HP 6978 whines

[coolhandluke999]

Hi,

I just purchsed a HP 6978. The one issue I have is when I use the ADF, the printer emits a high pitch whine.  This printer is just out of the box so it should not be a clenaing issue.  Whern copying from the glass plate, there is no whine.

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. 

Let's reset the Printer:

1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
7. NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
8. Reconnect the power cord to the rear of the printer.
9. Turn on the printer, if it does not automatically turn on.
10. Wait until the printer is idle and silent before you proceed.

Try to print. If the issue persists, continue to the next step.

Clean the paper feed rollers and separator pad in the ADF.

1. Remove the originals from the ADF.

2. Lift the cover of the ADF.

2. Check for obstructions inside the ADF. Make sure nothing blocks the paper from engaging with the rollers. Even small pieces of paper can cause paper feed issues.

3. Lightly dampen a clean, lint-free cloth with bottled or distilled water, and then squeeze any excess liquid from the cloth.

4. Press the cloth against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove any dust or dirt buildup.

5. Allow the rollers to dry completely (approximately 10 minutes).

6. Close the ADF cover tightly at both ends.

Let me know if this helps.

Hi,

I had performed all fo the steps above with no change, however I would have been surprised if they worked since this printer is just out of the box.
