I have an HP laserjet 2420 which has suddenly started making an alarming cracking noise when printing. I have checked the papertrays and nothing seems to be amiss. Any ideas?

Looks like you have a clogged/possibly damaged heads and head alignment issues. Do the alignment procedure and check the manufacturer support website or Google for the factory reset button combination of the printer. Cheers, Mike.

Here's a few links that might help you with the printer in general.

Thanks

remanufactured / compatible toner? sounds like defects to me. try OEM, or another supplier

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!!

Go into your print setting and check the box the has 'print on both sides'. It can easily done if you installed the HP toolbox software.

Most likely to be the toner cartridge is it OK on other programs such as the web explorer? If not change the toner cartridge you can also print out the configuration page by pressing the green tick and then using the up and down arrows select information press green tick to enter then move to "Print Configuration" and select using the green tick. If the page comes out OK then the print cartridge if fine if not try changing it. Also there maybe in the driver you have under printing preferences negative mode make sure that is not checked.

Failing this reinstall the print driver from HP Online if this still doesn't work then change the data cable if still not working then I suggest that the printer formatter board is faulty.

I do hope this helps you and please rate me
Thanks J
