According to the specs, this printer does not have a duplex unit and therefore cannot print double sided prints.
DOUBLE SIDED PRINTING USING A SINGLE SIDED PRINTER
If your printer does not have a duplex unit then the printercannot print double sided pages automatically.
You can print double sided pages but you have to do it one page at a time.
First print Page 1 then place the page back into the paper tray, but turn thepage upside down and the print Page 2.
Then print page 3 on one side then page 4 on the other side and repeat for therest of the document.
I suggest you try a test page first, to get the printing the right way up onboth sides of the page so it reads correctly.

You need to go into the print driver on your Windows machine and go to the Device settings tab. One of the settings is to set whether the unit has a duplexer or not. It does not always set automatically.

Either a dirty paper path or possibly a defective fusing assembly

Hi,

I had the same problem. It was due to incorrect properties in the printer settings.

1. Go to Start >> Printers and Faxes
2. Right-click on the HP 2420 printer and select Properties.
3. Go to the Device Settings tab.
4. Under Installable Options, set Duplex Unit to Installed.

Also, make sure that the Printing Preferences are set to Two Sided Printing:

1. Go to Start >> Printers and Faxes
2. Right-click on the HP 2420 printer and select Printing Preferences.
3. Go to the Printing Shortcuts tab.
4. Select the Two Sided (Duplex) Printing option.

That should do the trick.

HP - please change your setup so that this is set by default!!
