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.

the laser beam is block you need to open the printer and unjammed since every time you put a toner cartridge there is a fin that moves the cover over the laser or maybe you have a faulty cartridge that the fin is broken

I would love to see what the page looks like because I am sure that the word "soiled" doesn't quite mean the same to me as it does to you. See if you can't attach a picture or scan of the soiled side, and also see if you can rub the toner off the soiled side of the page.
Also provide tp/bottom/left/right half.
Thanks.

On your PC, clear the print queue. Power the printer on and see if the error reappears. If no, there was a corrupted print job in the queue. Power off printer, unplug the network cable, power on and see if error reappears. If yes, upgrade the firmware

Here's a few links that might help you with the printer in general.The HP LaserJet 2400 Series Manual - This covers 2410/2420/2430 HP LaserJet Printers. I uploaded it to my dropbox and this is the shared link for the .pdf file.HP Laserjet 2400 Series Software Manual - 2410/2420/2430 LaserJet PrintersHere's the HP2400 Series Software Manual - I've also uploaded this to my dropbox account.

This is a firmware error, that may be caused by corrupt printjobs or network issues. Try to see if you can narrow down the problem to a specific application and also check the URL below for any firmware updates. The problem can also be caused by faulty firmware dimms, memory dimms, or a faulty formatter board, but the message normally persist when this is the case. Go to htpp://www.hp.com/ support/LJ4200 or htpp:// www.hp.com/support/ LJ4300. Select Download Drivers and Software. Check for the latest firmware image version at the bottom of the page. If this firmware image is newer than the one installed on your printer and your printer can receive a firmware update, download the newer firmware upgrade. Not all HP LaseJet 4200/ 4300 printers can receive firmware upgrades.

Does it give a 49.FF95? As their is no such error code "FF95" for a HP 2420. However I've seen 49. XXXX error codes before (XXXX meaning weird Alphanumeric Characters and numbers). This type of error code you can try a couple of Items:
1st - Perform a Cold Reset:
1. Turn the printer off.
2. Hold down the SELECT button, and then turn the printer on. Continue holding down
the SELECT button until all three printer control-panel lights flash once and then
remain on. This might take up to 10 seconds.
3. After the message SELECT LANGUAGE appears on the display, press the
UP ARROW button or the DOWN ARROW button until COLD RESET is highlighted.
4. Press the SELECT button. The printer performs a cold reset and then continues its
power-on sequence.
5. Check all I/O settings and reset any customer-set printer configuration values

If the machine still comes back to the Strange FF95 error I would start with the replacement of the formatter,
Part Number for the Formatter:
Network versions Q3955-60003
Non-network versions Q3953-60001

Hope this helps..

Hi there sound to me like the toner cartridge is either faulty or leaking. Is it or has it been refilled if so remove cartridge vacuum out the insides of loose toner install brand new toner cartridge then test again. It cannot be the fuser unit as it will have quality problems all the time so try above and I hope it works for you.

Thanks J

Just do 2 steps:

1. Press Stop.
2. If the display highlight "Resume". Press the OK (Check Button).

The display will tell you that a Non-HP Cartridge is installed and Economode is Disabled.
At least, you can now print. The display will show back again to "Ready".

Check the pick up rollers in the tray and look for signs of wear. Most likely this is your problem.

Your printer may be out of toner, or the drum is not transferring toner to the paper correctly. Try replacing the toner and/or drum in your LaserJet to see if the issue is resolved.
