Grinding gears on double sided printing

[Zara13]

I used to have no problem doing double sided printing.  Now after the first page is printed and the paper goes back in I hear lots of grinding sounds like gears not in synch.  I have no idea what to do about it.  Of course I'm no longer on warranty.  Any ideas?

@Zara13, Welcome to the HP Support Community!

This could be an issue with the rollers. Let us try these steps to resolve this issue:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

If the issue persists, this could be a hardware issue. If the printer is out of warranty, I suggest you upgrade the printer. You may visit Hp Store to check the available printers.
